CJmnkal Philosophy. TOT 



of the age, we may mention Bishop Watson, Mr. 

 Nicholson, Dr. St. John, Mr. Henry, Mr. Par- 

 kinson, Mr. Cruikshank, Dr. Darwin, Lord 

 DuNDONALD, Dr. AusTiN, Mr. Lambe, Mr. Hig- 

 gins, and Dr. Thompson, of Great-Britain; 

 Messrs. Chaptal, Monge, Monnet, D'Arcet, 

 Beaume, Lemery, Cadet, Thouvenal, La Me- 

 THERiE, Adet, and Seguin, of France; and Junc- 

 ker, Schrgeder, Wenzel, Henkel, Jacquin, 

 Meyer, Crell, Van Romberg, and Hermstadt, 

 of Germany; to say nothing of many others, 

 equally entitled to praise, in almost every culti- 

 vated part of Europe." 



From the above general statements, it appears 

 that within the last half century the empire of 

 chemistry has been wonderfully extended. It is 

 but a short time since this science recognized, as 

 the subjects of her sway, only a few metals and 

 viedicines. She has lately subjected to her sceptre 

 the various kinds of earths found in the composi- 

 tion of our globe; the different /?z^/(^^' with which 

 we are conversant, whether of the aqueous or ga- 

 seoiis form ; the various kinds of vegetable, animal, 

 and mineral bodies which surround us; and almost 

 every substance capable of composition or analysis. 

 In short, she has extended her claims to every 

 species o^ animate and inanimate matter, and main- 

 tains authority over a territory of physical science 

 which may be called immense, when compared 

 with her former dominions. 



But chemistry has not only gained, during the 

 eighteenth century, a great extent of empire; it is 

 also distinguished for having acquired, in the same 

 period, a more practical and useful cast than ever 



n The contributions made to chemical knowledge by most of the above 

 named gentlemen may be found either in distinct works, published by 

 themselves, or in the Philosophical Transactions^ the journal d<: Fhysiquc^ thc" 

 An/isles de Chimi.-, or other scientific journals.
