The author was one of the jurats of Gravesend on its original incorporation. 



' Some of these devices are of peculiar interest, as they anticipated by more than 80 years the ' Century of Inventions' by 

 the Marquis of Worcester [v. No*. 5505-6, ante']. No. 21 is supposed to be the earliest mention in our language of a ship's 

 log and line, the deviser of which was Humphrey Cole, of the Mint in the Tower. No. 75 is a night signal or telegraph, 

 afterwards used by Capt. John Smith, for which he obtained such renown. No. 110 seems to be a curious anticipation of 

 the telescope, apparently borrowed from the Pantometria by Digges (1571), while some have been brought forward as new 

 discoveries at Gravesend within the present century.' D. N. B.

' Boyle was the true precursor 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 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 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. He further ascertained the unvarying 

 high temperature of human blood, and performed a variety of curious experiments on respiration ', etc. etc. etc.
