EXTRACTS FROM EXCHANGES. 
liquid, the soft inside structure is pressed against the protruding 
uterus ; it pushes it back, slowly, evenly, from all sides, in every 
part, until without effort, struggle, injury of the membrane and 
without excessive work on the part of the obstetrician, the organ 
returns of its own accord, as it generally does when the reduc¬ 
tion has reached a certain point. 
Pancreatic Diabetes in a Dog. —Guided by the discov¬ 
eries of Von Nering and Minkowsky and those of Chanvean 
and Kaufman, in relation to the influence of the removal of the 
pancreas and the action of the secretion of that organ in the 
peculiar function of glucose formation. Professor Dicnanx, of 
Brussels, has published in the Annales the record of a post-mor¬ 
tem which shows that clinical observations in veterinary medi¬ 
cine can be found, as well as in human, confirming the correct 
demonstration of Von Nering and Minkowsky. The case was 
that of a little slut which presented all the evidences of diabetes 
o-lncosnria, polyuria, polydipsia, polyphagia, antophagia. 
Noth withstanding much care and selected diet she died in a 
most emaciated condition. The lesions of the liver were large 
and yellow ; the pancreas difficult to find and is reduced to the 
size of a short cord, about 3 centimetres (instead of 20 to 40, the 
normal length), the cord is hard, of a dull white color and 
seemed to be part of the intestines. The kidneys presented 
nothing very particular \ their capsule opaque, not ^ adhering , 
the tissue proper pale. The microscopic examinations of the 
pancreas revealed all the characters of atrophy with epithelial 
degeneration. 
Some Remarks upon Anesthesia of Horses. —Prot. 
Hendricks, in the Annales de Bruxelles, after considering the 
various modes of obtaining anesthesia in solipeds and of alle¬ 
viating the sufferings of animals during operation without plac¬ 
ing them under complete anesthesia ; also after observing how 
dangerous the administration of ether or chloroform may prove 
on Tccoiint of the violent struggles of the animal during its ad¬ 
ministration 5 and how he has tried to prevent these or guard 
against their severity, records a mode of administration, to pro¬ 
duce partial anesthesia, which permits him to perform mild 
operations, or prevent the severe struggles of the animal. To 
this effect he places a large muzzle on the horse’s nose ; a thick 
sponge is at the bottom of it, chloroform is poured on it, little 
at a time and by degrees, sufficient anaesthesia is produced to 
permit the complete manipulations of casting without struggles 
and fear of accidents. [If our memory serves ns right, this is a
