years, also from an capeiry. Both were fed on hay and oats and 
ate well, though the second animal had some fever. Three or 
four mona after eating they were killed. On dissection, diges- 
tion appeared to have taken place perfectly ; the lacteals were 
full of chyle, and the urine was alkaline. The livers were re- 
moved and at once examined; that of the well horse furnished 
a strongly opaline decoction, very rich in glycogenic matter, 
while that of the arthritic animal gave a limpid solution con- 
taining not a trace. The flesh of both animals contained dex- 
trin and sugar, from the food. It appears, therefore, that on 
the one hand, the formation of animal starch in the carnivora 
takes place upon food entirely free from carbohydrates, and on 
the other, that it ceases in the d diseased herbivora, even with 
ood rich in these substances. Beside the febrile state, th 
serliamnitinis ed tshioe, such as prolonged suffering, arrest ‘thi 
production; hence, healthy animals must be used for its ite 
onstration, paper closes with a new method for the 
reparation of the glycogenic matter. A filtered decoction of 
the healthy liver is mixed with glacial acetic acid in excess; 
a whitish precipitate of almost pure animal starch falls, while 
the albuminoid matters being soluble, remain dissolved. A 
diseased liver gives no precipitate; nor does the solution from 
any other organ. If a liver solution be divided into two parts, 
and acetic acid added to one, a heavy precipitate falls; the 
, on the addition of a little saliva, becomes transparent 
and gives no oes ar In this way, therefore, the presence 
of the glycogenic matter may be easily and rapidly recognized.
