and had a good healthy appetite. In about three months the twitchings had entirely ceased and did not return. I may mention that this dog was a powerfully-made, typical foxhound, of a celebrated strain which is now unfortunately becoming scarce. I think there can be little doubt but that, in this case at least, any change which might have taken place in the nerve centres was only temporary (I will not say functional, since so much doubt rests as to the real existence of such a condition), and that the sole cause was the anremic state of the body. I think the very indefinite post-mortem lesions so frequently conspicuous only by their absence (if we except the deficiency of hrematin in the blood), rather point to perverted nutrition as an exciting cause of the symptoms than to any definite organic changes of nerve cells or fibres. Although such changes probably exist in many cases and are beyond our ken, as in most cases of Dementia, etc., yet I think any such changes that may exist in Chorea must be only secondary to blood changes of a definite type.
AN INTERESTING CASE. BY S. M. WILSON, M.R.C.V.S., ARMY VETERINARY DEPART~ENT, ALDERSHOT.
TROOP horse, Gen. No. 1281, Royal Engineers. Bay mare, six years old. Admitted May 10th, r887, as suffering from Adenitis, swelling at inferior part of parotid gland (off side) as of an abscess forming. Fomentations applied, swelling subsided by degrees, and the mare was discharged cured on the 21st of May. She was not, however, sent to duty. There was considerable stiffness about the jaws; when the fingers were put into the mouth on the near side, the mare would move the lower jaw to the off·side and keep it in that position for some seconds, at times nearly a minute. She was very shy about the head, running backwards if approached quickly or sudd enly, and experiencing considerable difficulty in mastication. She was put on soft food, viz., bran mash and scalded oats, green grass and hay, left in a large loose box and placed under observation. Meantime it was discovered that during h er training, immediately before being admitted for Adenitis, she had reared up and fallen over backwards, the top of her head coming in contact with the stones. This much was reported to me when I took over charge on June 6th. I found the symptoms as above described. I found also that when the mare was turned into the paddock, she found a difficulty at first in getting the head

sisting of tissue somewhat firm and composed of numberless small oval fluke-shaped bodies. Two or more isolated abscesses in the muscular tissue and one in the Ligamentum nuchce (funicular portion) just behind the occiput; contents consisting of above material, more or less inspissated. Numbers of small masses of inspissated and encapsuled pus in muscular tissue between posterior face of occiput and upper portion of atlas. One mass in the superior portion of capsular ligament, between atlas and occiput, pressing on spinal cord to a slight extent. Exostosis of bone on posterior face of occipital protuberance, and a large, round exostosis on upper and anterior portion of wing of atlas on the right side. The rig ht condyle of occiput and rig ht glenoid cavity of atlas partially united, with removal of the articular cartilage and necrosis of contiguous bones. There had been sprain of inferior dentata atloid ligaments, and there was immense thickening of the superior ones, and of the capsule of occipito-atloid articulations. B1'ai12.-A depression of I by ~ inch on upper central portion of left cerebrum, corresponding to a protuberance on the cranial surface of left parietal bone. Thickening of periosteum in front and at suture of the two parietals. It is a noteworthy fact that th e parietal bones were enormously thickened. The specimens have been deposited in the museum of the Army Veterinary School. REMITTENT ANTH RAX. BY R. W . BURKE, M.R. C. V.S ., ARMY VETERINARY DEPARTMENT, LAHORE.
(Continuedfrom page 245.)
Post-mortem Appearances. -The blood was dark and viscid. In some of the larger vessels it formed into distinct, long clots-a similar condition having been described by Arloing in Charbon Symptomatique of the French. Ecchymoses in the subserous and submucous tissues, but especially beneath the peri, and endocardium were constantly seen. V.S. (I st Class), Clayton also informs me that, in th e latter situations, this lesion was never absent in a single case, his observations dating from August, 1886. The wall s of the heart were soft and flabby, and the peri-cardial sac contained a large quantity of fluid. The lungs were the seat of congestion, and catarrhal inflammation, being enlarged and increased in weight, owing to consolidation. The Peyer's patches were found congested, and the mucous coat of the stomach showed dark-brown, irregular patches of extravasation. Very often the entire mucous membrane of the small intestine appeared swollen and congested; in many cases, ulcerations were also noticed.
