SEARCHLIGHTS ON HEALTH. THE SCIENCE OF EUGENICSBy PROF. B.G. JEFFERIS, M.D., PH. D. KNOWLEDGE IS SAFETY. 1. The old maxim, that Knowledge is power, is a true one, but there is still a greater truth: KNOWLEDGE IS SAFETY. Safety amid physical ills that beset mankind, and safety amid the moral pitfalls that surround so many young people, is the great crying demand of the age. 2. CRITICISM.--This work, though plain and to some extent startling, is chaste, practical and to the point, and will be a boon and a blessing to thousands who consult its pages...

Physiology and Hygiene for Secondary Schoolsby Francis M. Walters, A.M.PREFACE The aim in the preparation of this treatise on the human body has been, first, to set forth in a teachable manner the actual science of physiology; and second, to present the facts of hygiene largely as applied physiology. The view is held that right living consists in the harmonious adjustment of one's habits to the nature and plan of the body, and that the best preparation for such living is a correct understanding of the physical self...

YOUNG FOLKS' LIBRARYA BOOK OF NATURAL HISTORYTHE WONDER OF LIFE, BY PROFESSOR, T. H. HUXLEY. Every one has seen a cornfield. If you pluck up one of the innumerable wheat plants which are fixed in the soil of the field, about harvest time, you will find that it consists of a stem which ends in a root at one end and an ear at the other, and that blades or leaves are attached to the sides of the stem. The ear contains a multitude of oval grains which are the seeds of the wheat plant. You know that when these seeds are cleared from the husk or bran in which they are enveloped, they are ground into fine powder in mills, and that this powder is the flour of which bread is made...

The Notebooks of Leonardo Da VinciPREFACEA singular fatality has ruled the destiny of nearly all the most famous of Leonardo da Vinci's works. Two of the three most important were never completed, obstacles having arisen during his life-time, which obliged him to leave them unfinished; namely the Sforza Monument and the Wall-painting of the Battle of Anghiari, while the third--the picture of the Last Supper at Milan--has suffered irremediable injury from decay and the repeated restorations to which it was recklessly subjected during the XVIIth and XVIIIth centuries...

GENERAL SCIENCEBY BERTHA M. CLARK, PH.D.PREFACEThis book is not intended to prepare for college entrance examinations; it will not, in fact, prepare for any of the present-day stock examinations in physics, chemistry, or hygiene, but it should prepare the thoughtful reader to meet wisely and actively some of life's important problems, and should enable him to pass muster on the principles and theories underlying scientific, and therefore economic, management, whether in the shop or in the home. We...

Young Folks' Library, Selections from the Choicest LiteratureTHE MARVELS OF NATURE BY EDWARD S. HOLDEN, M.A., Sc.D. LL.D. The Earth, the Sea, the Sky, and their wonders--these are the themes of this volume. The volume is so small, and the theme so vast! Men have lived on the earth for hundreds of the sands of years; and its wonders have increased, not diminished, with their experience. To our barbarous ancestors of centuries ago, all was mystery--the thunder, the rainbow, the growing corn, the ocean, the stars...

Good against evil; right versus wrong; the judicial system against the criminal world. The struggle is as old as mankind. Sometimes the lines are blurred as the 'good' punish the 'bad' - the warriors against crime have resorted not only to killing wrong-doers, but additionally subjecting them to "starvation or the withholding of fluid, by drowning, stoning, impaling or by exposing the wretched victims to the stings of insects or snakes." Newgate Prison was one of the most famous - or infamous - prisons in England from the middle ages until the nineteenth century. Griffiths, a prison administrator, takes us inside where we discover "man's inhumanity to man".

This is an account of Nellie Bly's travels through Mexico in 1885. The book was originally a series of individual articles that she submitted to the Pittsburgh Dispatch newspaper for publication. In them she described the conditions of the people and the political system she found in Mexico. Her narratives focused mostly on the impoverished and disadvantaged in a country whose government was extremely corrupt. Bly was perhaps what we now term a feminist, striving for the empowerment and independence of women...

Chapters follow the progression of a child from birth through working years.Thus, Chapter 1 traces the child from newborn to toddler stage in the home. It includes assumed rights of children and mothers, superstitions, diseases and treatments, and what missions are contributing. Continuing on, Chapter 2 compares homes in various countries, explains the need for teaching the mothers, and delves into roles of fathers and missions. Other chapters explore the importance of play, the clash between play and work, views on education, and the role of worship.

"The Royal Society is a Fellowship of many of the world's most eminent scientists and is the oldest scientific academy in continuous existence." . As scientists have explored the world around them, observed and tried to explain natural phenomena, they have been invited to present papers to the Royal Society. Edmond Halley was an eminent member of the society and gathered together some of the most interesting papers of his day. Today, we may see errors in the logic or calculations, based on current knowledge, but these papers are unedited and as presented at the time and show how scientific knowledge was expanding in the late seventeenth and early eighteenth centuries...

"There may seem to be a disappointing lack of prophesy in a book avowedly dealing with the future; but since I believe the women’s movement to be a seeking for knowledge and good, to show what is reasonable and good in the movement is to show what will persist and triumph. Through all our faults and mistakes, we women are aiming at better understanding and co-operation with men, and a better adaptation to one another of conditions and persons. We are having to hammer out for ourselves the right principles of government...

This little book, first published in 1948, is part of the Chicago Natural History Popular History series that explains difficult subjects in ways and terms we all can understand. It was published at a time in Anthropology when exciting things like carbon dating were first being used and refined. "Prehistory means the time before written history began. Actually, more than 99 per cent of man’s story is prehistory. Man is at least half a million years old, but he did not begin to write history until about 5,000 years ago...

For many people, the name Caroline Herschel will be unfamiliar, but she was one of the most significant women on the English scientific scene during the late 18th and early 19th century. Sister of the well known William Herschel , she first worked as his assistant in his astronomical works, and then went on to become a noted astronomer in her own right. She discovered eight new comets in her lifetime, and was the first woman to be paid for her contribution to science, and was awarded a Gold Medal...

The present volume has not been designed as a systematic treatise on astronomy. There are many excellent books of that kind, suitable for serious students as well as the general reader; but they are necessarily somewhat dry and unattractive, because they must aim at completeness. Completeness means detail, and detail means dryness. But the science of astronomy contains subjects that admit of detached treatment; and as many of these are precisely the ones of greatest general interest, it has seemed well to select several, and describe them in language free from technicalities...

This book, written in the late 1800s, is a book of chemistry that explains the whys and hows of cooking to trained chefs and laymen alike. The book deals with some compounds of common foodstuffs, like albumen or gluten, and illustrates what happens from a chemist's point of view during certain types of food preparation like roasting, frying, or stewing. A part of the chapters also details adulterations of food - thankfully since outlawed - and how to detect them in the finished product.

People learn from other people, and races have forever learned from other races. Herein we are treated to an in-depth understanding of categorized social characteristics of the Native American peoples, primarily those of the western U.S. as they existed at the time of book publication . 'In dealing with [the Native Americans] as a race, a people, therefore, I do as I would with my own race, I take what to me seem to be racial characteristics, or in other words, the things that are manifested in the lives of the best men and women, and which seem to represent their habitual aims, ambitions, and desires.' - Summary by Roger Melin & book foreword

Before welfare or rehab, what happened to those unfortunates who lost their way, fell through the cracks, were cast off by society? Men such as Andress Floyd and his wife Lillian stepped up. In 1908, the philanthropists converted a mansion in New Jersey into a refuge for homeless men and during the more than 30 years of its operation, more than 100,000 men stayed there until they were able to get back on their feet. In this volume, Floyd has collected 13 diverse true tales of what brought some of the residents to seek succor and enlightenment at the Self-Mastery Colony. - Summary by Lynne Thompson

Auguste Comte was from France and published this book in French in 1844. He made a very great impact on the sciences and claims to have “discovered the principal laws of Sociology." Comte says Reason has become habituated to revolt but that doesn’t mean it will always retain its revolutionary character. He discusses Science, the trade-unions, Proletariat workers, Communists, Capitalists, Republicans, the role of woman in society, the elevation of Social Feeling over Self-love, and the Catholic Church in this book...

Newton's observations on the optical spectrum were widely accepted but Goethe noticed the difference between the scientific explanation and the phenomena as experienced by the human eye. He did not try to explain this, but rather collected and presented data, conducting experiments on the interplay of light and dark. His work was rejected as 'unscientific' by physicists but his color wheel is still used by artists today. - Summary by Lynne Thompson

In preparing these Essays, my chief object has been to present scientific truths in a light and readable form—clearly and simply, but with an exact adherence to the facts as I see them. I have followed—here and always—the rule of trying to explain my meaning precisely as I should wish others to explain, to myself, matters with which I was unfamiliar. Hence I have avoided that excessive simplicity which some seem to consider absolutely essential in scientific essays intended for general perusal, but which is often even more perplexing than a too technical style...

This is a work written about the plague in France and how to prevent its spread. It is considered an important historical work for the understanding of transmittable diseases. - Summary by afutterer

This is a chronicle of the 19 most interesting inventions of the early 20th century. Some of the inventions are still in use and of considerable impact today, while others are examples of the strong belief in progress prevalent at the time would probably be frowned upon today. In this way, the author's account of how ice was made at the time will still be very interesting for readers today, but an account of how dynamite was going to be used in farming may be seen as humorous to the contemporary reader. The subjects are as varied as science herself is, and any reader and listener should find a subject matching his or her own taste. - Summary by Carolin

Henry asks his sister Mary about the sky. She tells him all about the Sun, the Planets, the Moon, Comets and Meteors, and Stars. Mary tells her brother about mythologies people believed about the earth and sky along with true scientific information.

This book is devoted to the study of invertebrate animals. While most people associate the word "animal" with fish, amphibians, reptiles, birds, and mammals, 90% of the animal species on earth are invertebrates, i.e., they have no backbone. Protozoans and invertebrate animals are found world-wide, from the bottom of the oceans to the the rain forests, ice caves, and our own back yards. Many invertebrates still reside in the oceans, while others dwell in our houses, back yards and gardens, in ponds and streams, and on the menus in seafood restaurants...

This little book is an expansion of two addresses delivered in January, 1889. One deals with sanitary issues in London. The other deals with medical issues, mainly through the lives and careers of physicians. Though ancients are included, the main emphasis is upon the sixteenth through nineteenth centuries. - Summary by Book Preface and David Wales

Written over a century ago, this comprehensive book offers insight into the methods used to research and compile a family history. As stated in the preface of the book, "Strong emphasis is laid upon the importance of employing the historical method..." which is sorely lacking in today's computerized compilations. - Summary by Roger Melin

The electric telegraph, together with the railway-train and the steamship, constituted the three most conspicuous features of late 19th century civilization. Indeed, it may be truly said that the harnessing electricity to the service of man for human communication has effected a change in political, commercial, and social relations, even more complete than that wrought by steam locomotion. This is the story of how the electric telegraph cable was laid across the floor of the Atlantic from Newfoundland to Ireland. - Summary by modified from the introduction

This book tells the stories of some of the baby mammals of the wilderness,—how they grow and learn day by day to take care of themselves. In hollow trees or down under water among the lily leaves, in the cool sea or on the rugged mountains, on the grassy plains or among the waving tree-tops, in the dark caves and burrows or hidden in the tangles underfoot,—all the world is alive with young creatures. - Summary by introduction

This is a volume of exploration into the newest inventions of the turn of the previous century. Journalist Archibald Williams walks the reader through diverse inventions which were changing the world at just that point in time. - Summary by Carolin

Mencken sharpens his pen and in a collection of short essays delivers acerbic opinions on issues and persons of the time. Among his targets in this volume are critics, H.G. Wells Thorstein Veblen, Arnold Bennett, William Dean Howells, Irvin S. Cobb. Mencken's critiques are delivered against a background of his own well known ethnic, racial, religious, and sectional prejudices. Not for the faint of heart, Mencken's prickly, yet unapologetic, prose reveals a window into American attitudes at the time they were written and their influences on the larger American culture. - Summary by DrPGould

Radioisotopes in Medicine is an educational booklet published in 1966 as part of the Understanding the Atom series by the United States Atomic Energy Commission. Written in clear language for the general public, the booklet covers the diagnostic and therapeutic uses of radioactive isotopes like technetium 99m and iodine 131.

Haven't you always wondered how to properly accept a formal dinner invitation? Perhaps you have a débutante under your wing, in which case you need to make sure her appearance in society goes perfectly, to increase her chances of a brilliant match. And what exactly would be your duties as her chaperon? These and many other questions are expertly answered by Marion Harland in this little volume. - Summary by Carolin

A severe earthquake, centered in the vacation area of West Yellowstone, Montana, shook the ground and its inhabitants and visitors on August 17, 1959, at 11.37 pm. A mountainside fell, a lake formed, roads and houses disappeared, people were trapped, people died. The author of this narrative went to the area the day after the quake, took first-hand stories of the catastrophe, researched in the following months, and wrote this account within a year of the shaking. The printed source has many informative photographs. - Summary by David Wales

John Dewey, an early 20th Century American philosopher, psychologist, educational theorist saw Social Psychology as much a physical science as Biology and Chemistry. This project encompasses Part 1 of 4 of his book Human Nature and Conduct. Dewey's uses the word "HABIT" as a specialized catch-all word to describe how a person and his/her objective environment interact. This interaction is the basis for moral judgement. Dewey writes: "All habits are demands for certain kinds of activity; and they constitute the self.” In other places he also asserts that "Habits are Will." - Summary by William Jones, Soloist

This book is composed of selections from Alexander Teixeira de Mattos’ Translation of Fabre’s “Souvenirs Entomologiques,” retold for children. It's made up of first-person narratives, and using his exceptional observation skills, gives us a close-up peep into the world of insects, including bees, wasps, worms, beetles, moths, and spiders, to name a few. When Fabre first published this work, as the Preface indicates, he was criticized by some scientists in his field for writing a scientific book that was "too interesting." - Summary by Devorah Allen

Translated from Italian, it delves into the physiology of love from a scientific standpoint, in beautiful writing.

Eminent British botanist Agnes Arber provides an authoritative history of printed Herbals -- books widely used in early modern Europe to catalogue the uses of different kinds of plants. While Herbals often reflected pre-scientific and magical beliefs about the properties of plants, Arber's work reveals that they were also critical to the early development of botany and medicine as empirical sciences. A classic in the history of science. - Summary by Josh Leach

The 1873 edition of the autobiography of the founding genius of the "Greatest Show on Earth," P.T. Barnum. It details his life and business struggles up to the year 1872. Not only a showman and a museum operator, but an antislavery politician, Connecticut state legislator, Mayor of Bridgeport, Connecticut, and temperance lecturer, Barnum lays aside some of the gilding to provide his thoughts on his career, economics, how to make money, and other issues of the day. - Summary by DrPGould

Some men write their lives to save themselves from ennui, careless of the amount they inflict on their readers. Others write their personal history, lest some kind friend should survive them, and, in showing off his own talent, unwittingly show them up. Others, again, write their own life from a different motive—from fear that the vampires of literature might make it their prey. I have frequently had applications to write my life, both from my countrymen and from foreigners. Some caterers for the public offered to pay me for it...

History and customs of the Irish and Ireland. A word of warning to the listener: The Wild Irishman contains the biased, uncomplimentary opinions of Englishman, Thomas Crosland. Remember this was written in the late 1800's and published in 1905. Crosland was hyper critical of Irishmen and women at a time when American cities often posted signs, "No Irish Need Apply." If you are Irish, as am I, try to not be overly offended or simply walk away. - Summary by John Brandon

Prior to the emergence of paleontology and comparative anatomy as scientific disciplines at the end of the 18th century, it was generally known that there were species of animals that had disappeared completely. The term "extinction" originally applied to the extinguishing of fires or erasing of one's debt. It was not until 1784 that the term extinction was used to denote the complete eradication of a species of living being. In 1901, Frederic A. Lucas penned an overview of vertebrate animals whose only evidence of being remained in fossil records. The book focuses primarily on vertebrate animals, from fish to mammals. - Summary by Jeffery Smith

"In the following Letters I have endeavoured to exhibit in their true light the singular natural phenomena of which old superstition and modern charlatanism in turn availed themselves—to indicate their laws, and to develop their theory." In 14 letters, British physiologist Herbert Mayo is giving the reader an overview of popular superstitions of previous times, like vampirism, somnambulism or even ghost sightings, and exposing how in previous times they were treated with fear, ignorance and intolerance, often leading to crime, while he endeavours to give rational explanations for the phenomena with the goal to find treatments and cures for the afflicted. - Summary by Sonia

In 1827 Thomas Southwood-Smith published The Use of the Dead to the Living, a pamphlet which argued that the current system of burial in the United Kingdom was a wasteful use of bodies that could otherwise be used for dissection by the medical profession. "If, by any appropriation of the dead, I can promote the happiness of the living, then it is my duty to conquer the reluctance I may feel to such a disposition of the dead, however well-founded or strong that reluctance may be". Southwood-Smith's lobbying helped lead to the 1832 Anatomy Act, the legislation which allowed the state to seize unclaimed corpses from workhouses and sell them to surgical schools...

The Natural History of Pliny the Elder is one of the largest single works to have survived from the Roman Empire. The full work consists of 37 books, covering more than 20.000 topics ranging from astronomy and mathematics to botany and precious stones. The book became a model for later encyclopaedias and gives a fascinating overview of the state of scientific knowledge almost 2000 years ago. This version of the Natural History has been adapted for a younger audience. This first volume contains Book I and Book II out of a total of 9 books.

In 1910, when this book was published, the advancement of modern mechanism was still moving at a rapid pace. It must have seemed like very day, new inventions were made to make life easier. Most of these are still very much in use today, such as the lawn-mower, automatic milking machines in the dairy industry, fire engines, and escalators. Learn about how these worked in this volume. - Summary by Carolin

In recent years the number of people interested in keeping amphibians and reptiles in captivity has grown rapidly. All too often, these same people have little knowledge of the proper care needed for their captives, nor do they know where to turn in order to learn the needs of their animals. It is the intent of the authors of this special issue to offer the proper information needed to successfully keep amphibians and reptiles in captivity. We are by no means THE experts on the subject, nor do we claim to cover all the facts. However, we do hope that enough information is furnished to answer most of the common questions asked by people. - Summary by Tom R. Johnson

John Woodhouse Audubon , son of the famous painter John James Audubon and an artist in his own right, joined Col. Henry Webb's California Company expedition in 1849. From New Orleans the expedition sailed to the Rio Grande; it headed west overland through northern Mexico and through Arizona to San Diego, California. Cholera and outlaws decimated the group. Many of them turned back, including the leader. Audubon assumed command of those remaining and they pushed on to California, although he was forced to abandon his paints and canvases in the desert…...

This is a collection of articles written by W. Mattieu Williams on different subjects, that in his opinion "are likely to be interesting to all readers who are sufficiently intelligent to prefer sober fact to sensational fiction, but who, at the same time, do not profess to be scientific specialists." This book offers and intriguing glimpse into the scientific ideas of late 19th century. Though nowadays these essays should not be seen as wholly scientifically accurate, they are still entertaining and in many basic aspects remain truthful. - Summary by Kikisaulite
