CHYLE. 355 



solutions were mixed and evaporated, and the residue treated 

 witlnvater and dilute spirit, wliicli took up the salts and extractive 

 matters, and left the hrematoglobulin. The extractive matters were 

 dried, weighed, and incinerated, and the salts thus determined. 



The thoracic duct of a horse that had been kept without food 

 for some time contained only a very small quantity of a reddish 

 fluid, with an alkaline reaction, from which a slight fibrinous 

 coagulum separated, and which, on standing, deposited a red 

 sediment, while the supernatant fluid was clear and yellow. 

 Blood-corpuscles were detected in the sediment, but they were 

 not numerous, and, for the most part, altered in form. Lymph- 

 corpuscles and a very few chyle-corpuscles were observed ; some 

 of the latter were of a remarkable size, and presented a resem- 

 blance to conglomerate fat-cells. 1000 parts of this chyle left 

 a solid residue of 39'5, of which 20 consisted of albumen, and 

 3-2 of oily fat. 



In order to obtain a larger supply of chyle, a horse was fed 

 on peas steeped in water ; it was shortly afterwards bled to 

 death, and the chvle collected from the thoracic duct. 



I obtained upwards of 600 grains of a reddish yellow alka- 

 line fluid, which was immediately stirred, in order to separate 

 the fibrin. In the serum there was comparatively little fat, 

 and only a small number of blood-corpuscles ; while, on the 

 other hand, the lymph- and chyle-corpuscles were abundant. 

 None of the large conglomerate cells observed in the former 

 chyle could be detected. 



The analysis of this chyle yielded : 



Analysis 55. 



Water 940-G70 



Solid constituents 59-330 



Fibrin 0-440 



Fat 1-186 



Albumen 42-717 



Haematoglobulin 0*474 



Extractive matters and salts .... 8-360 

 Ptyalin, and globulin or casein, with chloride of 



sodium and lactate of soda . . . • 1-780 



The analysis of the salts was not carried out. The amount 

 of soHd constituents, and especially of albumen, is considerably 

 larger than in the former instance, but the quantity of fat is 

 remarkably small.
