358 CIRCULATING FLUIDS: 



In the seventh analysis, the chyle was collected from the ab- 

 sorbents of the colon. 



The fat in these various specimens of chyle was partly solid, 

 and partly fluid; the salts Avere apparently the same as in the 

 lymph. The albumen left about 2^ of ash, which consisted of 

 equal parts of carbonate and siilphate of lime, together with a 

 little carbonate, hydrochlorate, and sulphate of soda. The di'ied 

 clot in analysis 2, yielded 9*072 of brownish red ash, consisting 

 of carbonate, sulphate, and muriate of soda, carbonate and 

 phosphate of lime, and peroxide of iron. 



Tiedemann and Gmelin have communicated the following 

 data regarding the influence of diet on the chyle. Their expe- 

 riments were made on dogs, and the chyle was taken from the 

 thoracic duct. 



1. After taking cheese the chyle coagulated very slightly. 

 The clot was little more than a pale red transparent film, and 

 the serum was slightly milky. The chyle contained water 

 950-3, clot 1-71, residue of serum 48-0. 



2. After the use of starch, the chyle was of a pale yellowish 

 white colour, and coagulated rapidly. It contained water 930"0, 

 clot and residue of serum 70-0. The clot was of a pale red 

 colour. 



3. After taking flesh, and bread and milk, the chyle was 

 of a reddish white colour, and coagulated rapidly, the clot being 

 of a pale red tint and the serum very milky. It consisted of 

 water 915-3, clot 2*7, and residue of serum 83-8, 



4. After the use of milk, the chyle presented a milky ap- 

 pearance, and the clot was transparent and of a pale red colour. 



5. After bread and milk, the chyle contained water 961-1, 

 clot 1-9, and residue of serum 37*0. 



6. After flesh, bread, and milk, the chyle was of a yellowish 

 red colom', coagulated firmly, (separating into a bright red clot, 

 and turbid yellow serum,) and contained water 933-5, clot 5-6, 

 residue of serum 609. 



Any explanation of the results of these investigations would 

 be superfluous, since it is obvious from them, that the food 

 best adapted to dogs, viz. a mixture of flesh, bread, and milk,
