A delightful and instructive Work for all who wish to learn THE SECRETS OF SCIENCE,

Explained and Illustrated in the most Popular and Amusing manner. Translated and Enlarged from " Les Récréations Scientifiques” of M. GASTON TISSANDIER.


N this book, as its name implies, the Principles of Science will be found given

in a popular and pleasing form-physical facts being illustrated and explained by a series of Experiments, without any elaborate apparatus or special pliances. To the mind of a NEWTON, the fall of an apple was suggestive of the grand truth of gravitation; and in like manner the action of the atmosphere, the pressure of Auids, the laws of sound, of colour, of heat, and an infinity of subjects, can be explained in a manner that shall render their study truly a recreation and an enjoyment, instead of a task. At the same time the explanations of all the experiments and exercises are based on scientific principles, and the recreations are not presented as mere tricks and puzzles, but as a method of teaching agreeably, yet accurately, undoubted scientific truths.

Under the title of “Science in the Open Air,” the reader is initiated into many interesting secrets of Animal and Plant life, the wonders of the Aquarium, and of Geology as shown in Fossils, &c., besides various Meteoro. logical facts. The young Botanist, Naturalist, and Geologist will find here a Companion in his rambles who will tell him many things worth knowing.

The reader is next introduced to a Course of “Physical Science with. out Apparatus.” Such ordinary appliances as a few wine-glasses and tumblers, bottles, forks, and some sticks of sealing-wax, and similar articles, will be found sufficient to demonstrate in the way of recreation, but on strictly scientific principles, the chief elementary facts of science in various directions : How and why water can be boiled in a vessel of paper; why water remains in a glass swung round in a perpendicular circle ; how sound is conducted by solid substances; how a glass globe filled with water becomes a microscope; and how various optical illusions are produced, &c. This portion of the work will be found a complete Scientific Treatise, without hard words or bewildering technicalities.

Next we come to " Chemistry without a Laboratory:" a few phials
