Page 19 - ... the accuracy of every chemical process, and ascertain the true composition of bodies by proving the weight of the compound to be equal to the weight of the substances which produce it. 32. Use of the Balance,-— The balance is to the chemist what the compass is to the mariner, and before its introduction as a means of verifying experiments, the whole science of Chemistry was a collection of disconnected and separate facts and theories. Until within a comparatively recent period it was supposed...
