The above contains the results of the authors' meridian-measurement in Spain, and as far North as the Shetland 

 Islands, and in connexion with it, Biot's determination of the second.s' pendulum at the various stations of the arc between 

 Dunkirk and Forment«ra, of which the results obtained were pronounced by Prof. Grant (History of Physical Astronomy) 

 ' The earliest data of this kind which fully deserved the confidence of astronomers.'

 numerous interesting chapters on the mechanics and chemistry of SIetallurgy, while the woodcuts illustrate in a remark- 

 able degree the contemporary metallurgical processes.

 written Manuscript on 18 II., giving a resume of 10 Lectures at Edinburgh University, 8vo. con- 

 temporary hf. calf, £1. 10s [c. 1770] 



An interesting relic of this celebrated chemist, the founder of quantitative analysis and of ])neumatic chemistry, 

 treating more fully ' Of the more general Effects of Heat ' and all the more valuable from the scarcity of his writings, which, 

 besides his graduation thesis, consist only of his posthumous ' Lectiues ' published in 2 vols, in 1804. His definition of 

 chemistry in the above MS. is interesting : 'the study of the effects of heat and mixture upon all bodies, whether natural 

 or artificial.' He also states that ' French and German Ghemists are more numerous than the English.'
