tine yield in the liver after death, one part of sugar; that he- 
patine and sugar differ widely in osmotic power, a fact which 
accounts for the retention of the former in the hepatic cells ; 
that the liver becomes strongly saccharine on ligating the por- 
tal vein ; that then the blood also gives the sugar-reaction, 
and in one case it was found in the urine; and that the in- 
troduction into the circulation of sodic carbonate prevents the 
diabetic state ordinarily induced by injury of the sympathetic 
system, 
(61.) In a paper read August 6th,* De Luca gives the Te- 
sults of his examination of the liver of a person who had died 
from cerebral congestion, whose pancreas was partially atro- 
phied. He found ist, that this liver contained saccharine mat- 
ter capable of reducing copper-tests and of fermenting with 
yeast ; 2d, that when washed free from sugar and allowed to 
stand, a new quantity was formed, thus proving the presence 
of glycogenic matter ; 3d, that when thus washed, glycogenic 
matter not capable of reducing copper tests or of fermenting, 
could be prepared from it ; and 4th, that this same whitish 
substance boiled with hydrochloric acid for a few minutes re- 
duced the tests, fermented and yielded a crystallized compound 
with sodic chlorid. DeLuca concludes therefore, that the gly- 
cogenic function of the liver was not at all modified by the 
disease of the pancreas. :

imal heat to its ordinary degree, are phenomena intimately 
connected and mutually dependent, 2d, Abstinence cannot 
long be supported in Jean animals ; it produces a very rapid 
lowering of the temperature which is coincident with the al- 
most complete disappearance of sugar in the liver, the blood, 
the lymph, and other liquids normally saccharine. 3d, With 
fat animals or those moderately so, the duration of the absti- 
nence—all the other conditions being the same—appears to 
be exactly proportional to the quantity of fatty matter held 
in reserve in the tissues ; so long as this fat exists in the ani- 
mal, its life is sustained, the sugar is renewed in the liver as 
well as in the other nutritive fluids, and the temperature of 
the body is not notably lowered. 4th, During hibernation, 
the activity of the sugar-production is prone to the - 
absorption ot fat. 5th, Fi y, in animals deprived 0
