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

 temporary hf. calf, 1. 105 [c. 1770] 



An interesting relic of this celebrated chemist, the founder of quantitative analysis and of piu'umatic 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 ' Lectures' 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 Chemists are more numerous than the English.'
