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

 a number of highly suggestive facts and 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 . . . He, moreover, actually prepared hydrogen and 

 collected it in a receiver placed under water ... 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 directed 

 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 specific gravities and refractive 

 powers of various substances, and made a notable attempt to weigh light,' etc. etc. etc. Agues M. Clerlce.
