afterwards that the sugar in the urine in diabetes comes from 
the liver,, where it is formed in greater quantity in con¬ 
sequence of a sanguineous congestion of this organ, either 
natural or provoked by some lesion, not of the medulla ob¬ 
longata only, according to Claude Bernard, but also of 
different parts of the spinal marrow or the brain itself. 
The author further adds, that MM. Luys and Dumont- 
pallier have communicated to the Biological Society, at the 
seance of February, 1861, some fresh pathological cases, 
which tend to prove that glucosuria is the result of an 
alteration in the medulla oblongata; they having observed 
the intense yellow, chamois-like tinge in the fourth ventricle, 
and the fatty degeneration of the nervous cells in the brain 
of persons who have died of diabetes. 
The author does not think it necessary to carry out these 
quotations relative to the connexion of diabetes with the 
affection of the nervous system any further. It must be 
borne in mind that in the case of the bitch there was not the 
slightest derangement in the function of the nervous system, 
and that on the autopsy the encephalo-rachidian axis was 
found to be perfectly healthy. The result is, that if glucosuria 
often coexists with lesions in the nervous centre, and appears 
even, as in the case of artificial diabetes, to depend entirely on 
it, yet this disease may also exist independent of any nervous 
affection. On the other hand, the liver was found to be 
completely stearosed in this case, and containing, at least 
after death, only some traces of glucose. 
An able experimenter, M. Bolin, of the Veterinary School 
at Alfort, has presented to the Academy of Sciences of Paris, 
at its sitting 5th of November, I860, a memoir on the pro¬ 
duction of sugar connected with the re-absorption of fat and 
the production of animal heat, in which he concludes that 
the re-absorption or the combustion of fat, the production of 
sugar, and the maintaining of the animal heat at its ordinary 
standard, are phenomena intimately connected and depending 
on each other, and that the production of sugar is equal to 
the re-absorption of fat for which it is substituted. In the 
case of the bitch the kidneys secreted a large quantity of 
glucose, which probably did not come from the liver, as it 
seems to have been the case in the experiments of M. Shiff, 
for this organ contained hardly any after death, and it could 
not come from the fat, for the liver and kidnevs were crammed 
with it, and still they contained no sugar after death. 
From these approximations it may be seen that the caseol 
glucosuria observed by Professor Thiernesse tends not only 
to show that animals are susceptible of being affected with
