This is an adaption of the electronic transcription made by Paul Hubbs and Bob Gravonic. Using microfiche of the original (Canadian Institute for Historical Microreproductions no. 42355) as a copy text, I've made corrections and added a considerable amount of material.

Young's Demonstrative Translation of Scientific Secrets;


A Collection of Above 500 Useful Receipts on a Variety of Subjects.

Printed by Rowsell & Ellis, Toronto, 1861.


The object of the present work is clearly announced in its title. It is to collect within a small compass the instructions of experimental knowledge upon a great variety of subjects which relate to the present interests of man. It contains above five hundred genuine and practical receipts, which have been compiled by the publisher with extreme difficulty and expense. A reference to the list of subjects which the work contains, will show that the publisher's researches have been extensive, while a comparison of the work with others of the same general character evinces patient labour, and cannot fail to give it pre eminence. While the track pursued is not new, it is more thorough, and more easily followed than that marked out by any previous compiler known to myself. The work contains not merely the outlines on the subjects to which it refers, but, what appears to my own mind one of its excellences, the full and clear explanations of these subjects. To all classes of people, without exception, the work is of great value. It is fit, on every account, that the publisher should be encouraged in this production. The work is worthy the acceptance of all, and one which every man may prize.


Any bunch of roses or flowers, or anything of the kind that you admire, take the pattern of by placing them against a light of window glass, then lay a piece of white paper over them, and through the latter you will see the roses, &c. Now with a lead pencil take the pattern of the roses, &c., on the paper; when you have them all marked, cut then out with a scissors, so that you have a complete pattern of them. Now take a piece of glass, whatever size your pattern requires, stick the pattern on it with wafers, then paint the glass all over, except where the pattern covers, with black paint, composed of refined lampblack, black enamel, copel varnish and turpentine, mixed. Now let this dry, then take off your patterns and paint your roses, flowers, &c., with tube paints, mixed with demar varnish, so that your roses, &c., may be, in a manner, transparent. Paint your large roses red, some of the smaller ones yellow, or any colour to suit your taste. Paint one side of the leaves a darker shade of green than the other, which will make the picture appear as though the sun was shining on it. When this painting is dry, take silver or gold foil, (gold is best,) wrinkle it up in your hand then nearly straighten it, and cover the back of the glass all over with it; over the large roses let the wrinkles be larger, over the small ones smaller, &c.; then lay a piece of stiff paper, the size of the glass, over the foil, and a piece of very thin board again over this; have it framed in this manner and it is completed. You now have one of the richest of paintings, which is commonly taught at a cost of $5. You may buy all you require for this painting at the druggist's.


This is for transferring any picture plate you please to glass, to be framed. First give the glass a coat of demar varnish; let it remain for eight hours, or until dry; at this time have your picture thoroughly soaked in warm water; then give the glass another coat of demar varnish, and take the picture out of the water; then let it and the glass remain for twenty minutes, by which time the water will be struck in from the face of the picture, after which you will place the front of the picture on the varnished glass, (avoiding wrinkles and spots of water,) press it well on until every part is stuck fast, then carefully rub the paper all away to a mere film; give the glass then, over this film, another coat of demar varnish, which will make the film transparent; let it dry; then place the glass, with the varnished side towards you, between you and the light, and you will see the outlines of the picture quite distinctly; you may then paint on the back with tube paints, mixed with a little demar varnish to assist in drying, to suit your taste...
