Hence food is a substitute for expenditure of animal strengtl; 

 To this may be added, that when an animal is distressingly exe 

 cised, the weight of carbon in the carbonic acid given off by resp 

 ration is at first increased^ afterwards gradually diminishes, ar 

 becomes much less when the animal is in a state of exhaustio 

 Rest alone is not then sufficient,, but rest and food soon restore tl 

 strength of the animal j and with its strength its power of score 

 ing carbon — a power which I conceive to be essential to anim 

 life, and which will probably furnish a solution to some of t 

 most difficult problems of animal physiology, including that oft 

 generation of animal heat.

DINNER IN HONOR OF PROF. UEBIG. , 



We doubt not that many of our readers will be pleased w 

 the remarks of Prof. Gregory at the Glasgow dinner, in Octol 

 last. They give a succinct view of the labors of this distinguisl 

 man, and the contributions he has made to science. For this r 

 son, they are deserving of a place in our columns. It is true, t ' 

 this speech contains a few words which may not be intelligible < 

 all our readers ; still, by far the greater part is, and may be p 

 sented with profit and pleasure. 



" Professor Gregory, on risng, was loudly applauded. My L ' 

 and Gentlemen, he said, in proposing, as I have been requester 

 do, ' The Progress of Organic Chemistry,' I may perhaps 

 allowed briefly to direct yaur attention to its recent history, m 

 especially in connection with the name of our honored gu ' 

 (Cheers.) Before his time, the analysis of animal and regets 

 bodies was a most tedious and difficult operation. By his 

 provementSj and especially by his admirable invention of the j 

 ash apparatus for determining the proportion of carbon, he i 

 dered organic analysis so easy and so sure, that the chemist can r 

 undertake, and complete in a few weeks, researches which wc I 

 formerly have demanded years of labor. (Cheers.) A glano t 

 the former and at the present state of organic chemistry wc I 

 give the best idea of the value of Liebig's improvements ; ^ 

 it ought to be specially noticed, that, although his methods h ' 

 been now and then objected to, they are at this day, universi 

 employed by chemists. (Applause.) Armed with the powe 1 

 weapon of a sure and easy method of research, Liebig, in 16 > 

 took the field in organic chemistry ,• and the trophies of his pro\» * 

 are seen in an uninterrupted series of the most splendid orig 1
