hairs together ; is easily raised with the epidermic layer, which 
exposes a little cavity. The dermic surface underneath is a 
pale rose, and shows embedded in it a blackish little parasite. 
With strong pressure and fine forceps it is extracted. Case IL — 
A horse has his legs covered with pimples from the foot up to 
the knees and hocks. No fever, no itching. The crusts of the 
papulae raised show the same little parasite, which when placed 
on the hand moves away rapidly. Prof. Neumann recognized 
these parasites as nymphae of ixodes reduvius . The diagnosis 
is easy, and the treatment consists in the extraction of the in¬ 
sect from the papulae.—( Revue Veter in.) 
Pseudo-Meningitis due to Prevertebrae Abscess of 
the Neck [Prof. Cadeae~\. —A six-year-old horse, after suffer¬ 
ing with distemper, complicated with facial paralysis, later pre¬ 
sented alarming symptoms : loss of appetite, severe constipation, 
painful action in moving, paresia of the right lateral biped ; the 
right eye was partly closed, ears erect and stiff, jaws contracted ; 
the membrana nictitans covers the eye as soon as the hand is 
passed before it. There is contraction of the neck, and the skin 
of that region is the seat of severe hyperasthesia. The animal 
rebels against exploration of the poll. Pockjaw was at first 
suspected, when a fistula appeared on the superior border of the 
neck, from which abundant suppuration escaped. The horse 
was thrown, the fistula freely opened, and masses of necrosed 
cervical ligament were extracted. Very rapidly the horse im¬ 
proved, and all symptoms disappeared. These meningeal man¬ 
ifestations seem to have been entirely due to the pressure of the 
pus upon the roots of the nerves of the rachidian opening.—

Tetanus : Contribution to a New Treatment [Dr. 
G. Fontibasso ] ,—This mode of treatment had already been tried 
by M. Trelut, who obtained a recovery by it. The author hav¬ 
ing a severe case in a six-months-old colt, due to a mild punc¬ 
ture of the foot, in which the symptoms were exceedingly 
severe, decided to experiment with the treatment of M. Trelut, 
viz., hypodermic injections of blood from the sick animal. After 
shaving and disinfecting the skin, the author extracted 50 
grammes of blood from the left thoracic vein, and injected 5 
grammes on each side of the neck. The balance (40 grammes) 
is kept in a dark, cool place in a sterilized bottle. The next 
day injections of 5 grammes of the serum of that blood, mixed 
with 5 of tepid sterilized water, are made. In the evening an¬ 
other bleeding of 10 grammes, the serum from which is injected
