WILSON, PRINTER, 57, SKINNER-STREET, LONDON. THE POLYTECHNIC LIBRARY. The design of the Publishers of the POLYTECHNIC LIBRARY is to produce a Series of highly-instructive Works, which the Public may be tempted to _buy_, because they will be cheap,--be induced to _read_, because they will be brief,--be competent to _understand_, because they will be clearly written,--and be able to _profit by_, because they will be WORKS OF PRACTICAL UTILITY. Every volume, therefore, will contain _a complete Treatise_ relating to one of the useful arts or sciences, or the chemical or mechanical trades. JUST PUBLISHED, PRICE HALF-A-CROWN, VOL. I. OF THE POLYTECHNIC LIBRARY, _Neatly printed in_ 18mo. _and bound in_ Cloth, _containing_ THE ART OF GLASS-BLOWING, _Or Plain Instructions for Making the_ CHEMICAL & PHILOSOPHICAL INSTRUMENTS WHICH ARE FORMED OF GLASS; Such as BAROMETERS, THERMOMETERS, HYDROMETERS, _Hour-Glasses_, _Funnels_, _Syphons_, TUBE-VESSELS FOR CHEMICAL EXPERIMENTS, TOYS FOR RECREATIVE PHILOSOPHY, &c. BY A FRENCH ARTIST. ILLUSTRATED BY UPWARDS OF ONE HUNDRED FIGURES, _Elegantly engraved on Copper plates_. Artists and Students of the Experimental Sciences will find this work adapted to aid them effectually in the economical preparation of their Apparatus; and persons who would willingly occupy their leisure hours in practising the charming art of working Glass and Enamels with the Blowpipe, but who have hitherto been deterred by the anticipated expense of the instruments, and the imaginary difficulties of the undertaking, are taught herein the simplest, most expeditious, least expensive, and most effectual methods of working Glass into every variety of useful or fanciful device.
