224 Analysis of the Chyle of the Horse. [Sept, 



cient to make the characters and nature of vegetable substances 

 disappear entirely. The powers which preside over digestion 

 must be very active and very powerful. 



From this first analysis, it follows, that the chyle of the horse 

 is composed : 



1 . Of albumen, which constitutes the greatest part of it. 



2. Of fibrin, or at least of a substance which resembles it in 

 several respects. 



3. Of a fatty substance, which gives to chyle the appearance 

 of milk. 



4. Of different salts, such as potash, muriate of potash, and 

 white phosphate of iron; that is, phosphate at a minimum of 

 oxidation. 



I ought not to neglect to mention here that M. Emmert was 

 occupied before me with analysing chyle. An extract of his 

 work, by M. Friedlander, is printed in the Annates de Chimie 

 for October, 1811; but as there is some difference between the 

 results which we obtained, I thought it right to publish my ex- 

 periments. 



After having written thus far, I received from M. Verrier a 

 new quantity of chyle, the analysis of which furnished nearly 

 the same results. However, as this last portion was not coloured 

 like the preceding, it presented some phenomena which were 

 not perceived before, and which I shall relate in a few words. 



Chyle from the Stibium bar Branches. 



It was white, like milk. The bulky coagulum which it con- 

 tained was red in some parts. Water deprived the coagulum of 

 the greatest portion of this colour. Then it resembled fibrin, 

 but had much less tenacity. 



The white liquid which surrounded this coagulum beingleft at 

 rest for 18 hours was i'ound partly covered with drops of a 

 yellowish oil. The same liquid treated with a considerable 

 portion of boiling alcohol let fall a great quantity of albumen. 

 The alcohol assumed a yellowish green colour, and deposited, on 

 cooling, a white oily concrete matter; and yielded, when evapo- 

 rated, an additional portion of yellowish oil. These phenomena 

 confirm me more and more in the opinion stated above, that the 

 oil of chyle is of the same nature as that which exists in the 

 brain. 



The chyle deprived of the fatty matter by repeated digestions 

 in boiling alcohol becomes transparent by drying, as happens 

 to the brain. 



A portion of this chyle coagulated by heat, and then incine- 

 rated, furnished carbonate of potash, muriate and sulphate of 

 potash, iron, and phosphate of lime. 



Among the last portions of chyle sent me by M. Verrier there
