EXTRACTS FROM ITALIAN JOURNALS. 
The last case was that of a donkey, which had died in con¬ 
sequence of an experimental inoculation of tetanus. This 
animal was old and in poor condition, and was affected with 
immobility, besides which he presented the peculiarity of 
constantly pushing with the left side of the body, as if about 
to fall on that side. The cranial walls were removed, and 
the brain exposed. On the left, upon the frontal lobe, the 
dura mater was strongly stretched and so much thinned that 
it showed underneath a large pouch covered by the pia- 
mater, and as soon as the dura-mater was opened a cyst as 
large as an egg escaped from the left lateral ventricle, while 
within this there was another of the same size. The left ven¬ 
tricle was largely distended, and the cerebral substance at 
the anterior part of the frontal lobe was entirely destroyed. 
The cyst was an echinococcus in which germinal and hyda¬ 
tid membranes were well presented. 
The post-mortem examination of the right eye failed to 
reveal anything abnormal, but the left showed, besides the 
atrophy of the crystalline lens and the diminution in the quan¬ 
tity of the vitreous humor, a hemorrhage of the central artery 
of the retina. 
The conclusions are: 
i st. Cerebral echinococcosis is observed in animals as 
well as in human patients. 
2d. That the examination of the eye has shown serious 
lesions of the retina and of the optic nerve. 
3d. That the functional disturbances due to the presence 
of a cerebral echinococcus may vary considerably .—II Mo.

SUBCUTANEOUS CAUTERIZATION. 
By M. Rabbaglietti. 
The horse which was subjected to this treatment had for 
some time been lame, and had received blistering applications 
on the shoulder, but without any favorable result. The actual 
cautery was then decided upon, and, the animal being thrown, 
some twenty cutaneous incisions were made in four parallel 
lines, measuring about three centimeters (one inch and a half) 
in length. These incisions were quite deep, and partly in¬ 
cluded the muscles underneath. The cautery was then twice
