horse submitted to the experiment, but also to analyse and 
compare the lymph with that in the normal state. To obtain a 
sufficient quantity, I inserted a tube in one of the lymphatic 
vessels which runs alongside the carotid artery; the spot 
selected was about the middle of the neck. One of my pupils 
undertook to collect it during six days. Professor Wurz 
analysed it, and, compared with the normal lymph, found it 
to be as follows : 
Water .... 
913-520 
955-384 
Fibrine ....

Albumen and organic matter of tlie

This fluid is, consequently, richer in plastic elements. There 
is also more albumen, more fatty matter, more salts, and 
almost as much sugar, as in the lymph of horses fed in the 
usual way, only there is less fibrine. Its composition is in 
harmony with that of the blood; this is as it ought to be, the 
first of these fluids being at the same time a portion and a pro¬ 
duct of the second. Let us now pass to another point. The 
liorse in question, during the thirty days he was deprived of 
food, only consumed 2666 grammes of his substance, for the 
renewal of tlie blood and to repair the loss by the secretions. 
Tliis small internal ration sufficed -to maintain the regular 
animal heat. Everybody knows that one of the most indis¬ 
pensable conditions of animal life is that of maintaining the 
temperature of the body at a certain degree, which is con¬ 
stant. When the temperature of the body falls to 24 or 25 
centigrades, death takes place. As long as the combustible 
matter abounds in the svstem, the calorification is active; as 
soon as it decreases, the calorification languishes. This has 
not been the case in this instance, as the muscular and adi¬ 
pose systems have been able to furnish an adequate quantity; 
thus the horse in question had maintained his temperature to 
a degree from the first to the thirtieth day of his deprivation 
of food with so very slight variation, that it is not neces¬ 
sary to mention it here. Ail these indications were taken by 
a metastatic thermometer, very easily affected, constructed 
by M. Walferdin. The persistence of the animal heat at the 
usual degree is exceedingly curious, it having been overlooked

selected fat animals for their researches; but it cannot be 
considered as constant, as it is subordinated by the presence 
of fat. As long as the adipose tissue exists in an animal de-
