' Boyle is the true i)recursor of the modern chemist. Besides clearing away a. jungle of perplexed notions, he collected 

 a number of highly, suggestive facts t^nd observations. He was the first to distinguish definitely a mixture from a com- 

 pound ; with him originated the definition of an 'element' as a hitherto undecomposed constituent of a compound ; he 

 introduced the use of vegetable colour-tests of acidity and alkalinity . . . lie, moreover, actually prepared hydrogen and 

 coUectetl it in a receiver placed underwater ... In physics, besides the great merit of having rendered the air-pump 

 available for experiments and discovered the law of gaseous elasticity, he invented a compressed-air pump, and directeil 

 the construction of the first hermetically sealed thermometers made in England. He sought to measure the expansive 

 force of freezing water, first used freezing mixtures, observed the effects of atmospheric pressure on ebullition, added con- 

 siderably to the store of facts collected about electricity and magnetism, determined the sppicific gravities and refractive 

 powers of various substances, an<l made a notable attempt to weigh light,' etc. etc. etc.— Aijiies M. Ckrkc.

In this important work the author confirms the fact, first discovered by Jean Rey, that metals actually increase in 

 weiglit after being calcineil— the one sore point that did not agree with the phlogiston theory, and was explained away 

 with a vast amount of ingenuity by its adherents.
