75'05 grammes of nitrogen^ 21*15 grammes of salts.* If 
this animal had been fed as usual, he would have easily con¬ 
sumed 7500 grammes of hay and 2270 grammes of oats; 
representing, according to the analysis of M. Baussingalt, 
3938 grammes of carbon, 446 grammes of hydrogen, 139 
grammes of nitrogen, and 672 grammes of salts. But 
if the deduction is made of the parts which have not been 
absorbed, but have been rejected as excrements, the amounts 
really taken would be 2574 grammes of carbon, 266 grammes 
of hydrogen, 6l grammes of nitrogen, 69 grammes of 
salts. Consequently, a horse consuming 2666 grammes of 
his flesh, being one third fat and two thirds muscle, only 
uses about one third of carbon, one half of hydrogen, and one 
fifth of the salts he would have used in his rations, and had he 
received them in the usual way, only the same quantity 
of nitrogen; lie, therefore, lived with great economy. Let 
us now see how he used this moderate ration, or rather how 
he employed it; we know that it is necessary to reconstitute 
the blood, and to maintain the animal heat, the pulmonary 
perspiration, the function of the skin, the secretion of urine, , 
&c. We assert that the reabsorbed substance must renew the 
blood and maintain it in all its integrity in respect of quality 
and quantity; this is, in fact, what does happen. Until the 
last day the pulse indicated by its fulness and strength that the 
vascular system was tolerably full, and on the 30th the blood 
rose to one metre seventy centimetres in Haleys tube. Its 
strength was, therefore, not far from normal, and it is not 
too much to say that the beatings of the heart had almost 
preserved their usual energy. The temperature of the blood 
was only one degree less than at the beginning of the experi¬ 
ment; there was only a difference of one tenth of a degree 
between the temperature of the blood in the left and the 
right ventricles of the heart. The quantity collected from 
the carotids, jugulars, and venae cavae, as well as from other 
parts, amounted to 27 kilogrammes, being one twelfth of the 
weight of the bodj". The blood was not in any way less 
rich in fibrin, and had all the physical characters of blood 
taken from animals in good condition, which had been de¬ 
prived of food for a few days only. Its coagulum was covered 
with a white layer of a bluish shade, its serum was turbid, 
opaque, and lactescent, resembling chyle.
