The serum of chyle is, however, rarely quite transparent, and always 
contains globules; and Emmert,indeed,states that he saw red globules 
in the water in which he agitated the red coagulum of chyle. Hew- 
son also saw red corpuscules in the lymph of the spleen. Schultz 
(■Syst. cl. Circulation) and Gurlt (Physiol. d. Hciiissäugethiere) state, 
that they have found in the chyle, in addition to the proper globules 
of that fluid, a few blood corpuscules: and hence infer that the red¬ 
dish colour of the chyle is due to the presence of such red particles, 
of which they suppose the formation to begin in the chyle. 
Fibrin of the chyle,—its source.—The firmness of the coagulum 
of the chyle is different in different animals. The proportion of the 
moist and dried coagulum in the horse, dog, and sheep, is stated as 
follows by Tiedemann and Gmelin:—In 100 parts of chyle 
of fresh eoagalum of dry coagalara 
Of the horse, there were . . from 1.06 to 5.65 . . from 0.19 to 1.75 
Of the dog .... 1.36 to 5.77 . . 0.17 to 6 56 
Of the sheep .... 2.56 to 4 75 . . 0.24 to 0.52 
The contents of the thoracic duct coagulated more perfectly when 
the animals were killed while fasting. than when they had taken a 
--' ' s 
meal a short time previously: and the amount of fresh and dry 
coagulum was greater in the former case. The dry coagulum of 
the chyle of horses killed while fasting, amounted to from 1.00 to 
1.75: that of horses which had lately taken food, from 0.19 to 0.78 
per cent. 
Tiedemann and Gmelin have moreover confirmed Emmery's ob¬ 
servation, that the proportion of fibrin in the chyle increases with 
the progress of this fluid towards the thoracic duct. In a horse 
which recently had a feed of oats, the chyle of the iacteals which had 
» m 
not passed through the mesenteric glands, did not coagulate; while 
100 parts of the chyle of the Iacteals which had passed through 
those glands, afforded 0.37 of dry coagulum; the same quantity of 
the chyle of the thoracic duct 0.19, and the same quantity of the 
lymph of the pelvis 0.13. 
On the above facts Tiedemann and Gmelin ground their opinion 
that the fibrin of the chyle is not derived immediately from the food, 
but is formed in the blood and poured into the chyle and lymph by 
the glands of the absorbent system, and by the spleen. And since 
the chyle of the Iacteals that had passed through the mesenteric 
glands contained more fibrin than the lymph of the absorbents of 
the pelvis, they conclude that more fibrin is added to the chyle by 
the mesenteric gjands than by the glands with which the lymphatics 
of the pelvis communicate. However, the opinion that fibrin is thus 
added to the chyle is as difficult to prove as the opposite hypothesis, 
that the albumen of the chyle itself is converted into fibrin. To 
determine the correctness of either, it would be necessary to ascer- 
tain by a great number of experiments the quantity of solid ingre¬ 
dients, and particularly of albumen, in the serum of the fluid con¬ 
tained in diflerent parts of the absorbent system. If, for example, it 
were found that the serum of the chyle of the thoracic duct after the 
separation of the fibrin contained less albumen than the serum of
