EXTRACTS FROM EXCHANGES.

months). Both dogs' had congenital cataracts evidently of 
hereditary origin. The patient of the authors was successfully 
operated upon—not, however, without some difficulties, due to 
adhesions contracted between the lens and the cornea. The 
fact of these adhesions and the evidence of heredity for congeni¬ 
tal cataracts are the interesting points of this report.— {Rec. de

Ocular Manifestations in Purpura Complicating In¬ 
fectious Pneumonia \By MM. Ciattoni and J. .—Dur¬ 
ing a mild epizooty of infectious pneumonia, this horse, four 
years old, had presented symptoms of a very slight attack, and 
after some two weeks was considered convalescent. Bight days 
later he has a relapse : his walk is painful, the hind legs are 
weak, the fetlocks swollen and painful, the mucous membranes 
are yellow, his fever is high, there are centres of hepatization 
in the lungs, appetite is still good. Placed under treatment his 
pulmonary troubles improved, but his locomotion is getting 
worse. One morning he shows great increase in the severity of 
his troubles : his forequarter seems to be the seat of general 
tetanism, the head is extended on the neck, his countenance 
shows great pain, he moves altogether as of one piece, 
falls down, and rises with difficulty. The temperature has 
dropped below normal. The respiration is jerky and pain¬ 
ful. And there suddenly appear on the surface of the body, 
neck and abdomen, large subcutaneous tumors, characteristic of 
anasarca. The manifestations of the hsemorrhagic process on 
the left orbit are very peculiar ; the ocular globe seems to be 
dislocated; the conjunctiva is swollen and in less than an hour 
resembles a thick purplish cord ; the membrana nictitans, pro¬ 
truding in front of the eye, is oedematous and hangs on the 
nasal angle ; the mass of the eye itself is protruding, pushed 
from the orbit by the pressure of the blood on its posterior face. 
The animal died. Lesions of infectious pneumonia and of 
purpura were found.— {Jour, of Zootechnie^ 
Two Cases of Tetanus Following Amputation of the 
Tail — Antitetanic Serum \JBy M. A. Norey)^. —These 
two horses belong to the same pair, had been bought together 
and were both operated upon by the blacksmith, who, to ampu¬ 
tate the tails, used the peculiar shaped knife that serves to pare 
the hoof, the butteris. The symptoms occurred in both horses 
48 hours apart. They were put under the same treatment— 
chloral, bromide of potassium, quietness, etc. The horse that 
was affected first died the fourth day. The other on the second
