purpose and to exert no injurious effect ; instantly after death 
therefore, a strong potash solution was injected into the liver 
by the portal vein. In this liver no sugar was detected ; 
the liver, immediately after death, yields the same result, In 
one case, a dog was killed, a piece of the liver instantly sliced 
off and thrown into a freezing mixture of ice and salt; the 
absence of sugar in this portion was almost complete ; while 
the rest of the organs, which remained a short time in the 
animal, afforded 2-96 per cent of sugar. Division of the spinal 
cord, as already noticed by Bernard, suspends the production 
of sugar, This fact Pavy explains by showing that the body 
is thus cooled down so low—to 70° F.—that the post-mortem 
change does not go on with sufficient rapidity to afford sugar 
enough for detection. After a longer time, however, the liver 
becomes strongly saccharine. This view is sustained by the 
fact that if the temperature of the animal after section of the 
spinal cord, be artificially maintained, the ordinary amount of 
sugar is found in the liver ; and also by the farther fact that 
with rabbits whose coats are oiled, so that on exposure to cold 
their temperature falls, the same result takes place and sugar 
resists transformation during life, are questions which the 
author leaves for future researches to | Possibly 
some analogy to the latter condition is found in the fact that
