Cerebro-Spinal Meningitis Following a Deep Wound 
OF THE Poll \By Mr. Roy \.—This is the record of an interest¬ 
ing case, resembling very much what occurs in cases of pithing, 
though the researches instigated to find the true origin of the 
trauma remained undiscovered. It was that of a mare belong¬ 
ing to a regiment of cavalry, which was found one morning in 
her stall, lying down, struggling and unable to get up. After 
many efforts, and much assistance, she succeeded in rising, but 
was unable to stand and soon fell down. During her efforts to 
get up, a little stream of blood was observed escaping from a 
small wound in the occipital region. The symptoms presented 
by the animal were characteristic of severe cerebral lesions, 
cerebro-spinal, and notwithstanding an appropriate treatment, 
the mare grew worse so rapidly that she was destroyed. At the 
post-mortem the only important lesion found was the wound in 
the poll. It consisted of a small incision of the skin, with 
smooth edges, two centimeters wide, and extending in under 
the skin through the splenius, small oblique and great posterior 
straight muscle of the head, as far as the capsular ligament of 
the atloido-occipital joint. This, as well as the dura matei, had 
been divided and were the seat of a sero-bloody extravasation ex¬ 
tending to the cranial cavity. It was the internal haemorrhage 
and its extension to the bulb and pons varolii which had caused 
the paralysis and the serious cerebral symptoms exhibited by 
the truly pithed animal .—{Revue Veter.) 
Multiple Cysts and Generalized Anasarca in a 
FcETUS \^By Mr. A. Delmer '\.—After remarking that among the 
causes of foetal dystokia, due to diseases of the foetus, its mal¬ 
formations or its neoplasms, and which are mentioned by the 
authors on veterinary obstetrics, there are several which are not 
uncommonly met with, such as hydrocephaly, ascites, anasarca, 
contractures of various muscular regions, etc., there is one 
which has not been named, and that is the presence of cysts 
developed at the expense of the foetus itself. Having met with 
one case where the foetus had to be delivered by embryotomy 
he gives the description of the four cysts which interfered in 
the delivery : “ Four in number, they occupied various regions 
in the body and were of different dimensions. The largest, 
situated on the superior border of the neck, measured 24 centi¬ 
meters in length and 20 in width ; a second, smaller, occupied 
the anterior region of the right scapulo-humeral articulation ; a 
third the middle of the right thoracic wall, and a fourth the 
same place on the left side. Externally they had the form of
