animal heat quicker than larger beasts. Rabbits showed 
themselves especially robust, withstanding 20°-2 5 Q of cold 
between two blocks of ice ; after remaining twenty-four hours 
the temperature (body) fell i.8°, while that of the extremities 
fell 32 0 F. Sheep were equally vigorous, providing the fleece 
be kept dry. Swine and goats, possessing but little hair, 
maintained their vitality in a marked degree, although they 
suffered more or less subsequently. Dogs also withstood 
these frigid atmospheres, but horses were the least able to 
tolerate cold. Poultry proved themselves of startling vital¬ 
ity in this respect when the plumage remained smooth and 
unruffled. 
Complete Absence of One Eye m a Calf .—In a small heifer 
about three weeks old, killed at the public slaughter house 
at Gottingen, the left eyeball was totally absent, while 
the right member was perfectly developed in every par¬ 
ticular. The left eyelids were of normal appearance, but 
the optic cavity was occupied by fat and connective tissue in 
which degenerated muscle fibre could be seen. In a series of 
transverse sections of these contents examined by the micro¬ 
scope, the lens could not be distinguished. The optic nerve 
and foramen were absent. The peculiarity of this malfor ma- 
tion is in the fact that all epithelial formations, excluding the 
lids, were wanting. 
Rupture of Uterus .—On a certain night of this year 1 was 
called to attend a mare that had been six hours in labor. The 
foal had already succumbed ; from the lips of the vulva pro¬ 
truded an anterior and posterior foot, and a short distance 
within the vagina reposed the other two limbs—the presenta¬ 
tion was a posterior one. The presenting metacarpus was 
disarticulated at the carpus, and the limb retropelled in order 
to avoid wounding the mucous membrane of the genital pas¬ 
sages. Five men were stationed on a lope attached to the 
posterior extremities, and by steady traction the mare was 
gradually delivered. Immediately afterward a considerable 
hemorrhage oozed from the commissure of the vulva. Upon
