A CASE OF SYNCOPE LASTING FOR FIVE HOURS AFTER AN.l:ESTHESIA IN A DOG.

1\1. PECUS had brought to him in the month of September 1892 a bull-dog, aged six years, for treatment on account of a small tumefaction of the size of a nut seated on the right side of the nose. It was subcutaneous and fluctuating, and in its deeper parts apparently related with an ulceration of the buccal mucous membrane. It was thought that the case was one of simple abscess, and the swelling was therefore punctured from the mouth, with the result that only blood escaped and the swelling remained as large as before; it was then discovered that the swelling was in reality a tumour. This operation had an unfortunate effect, for during the next few days it started to grow very rapidly, and five days afterwards the owner consented to the extirp.ltion of the tumour. At 6.30 A.M. an injection of 3 centigrammes of morphine was administered, and a quarter of an hour later IS grammes of chloral dissolved in an infusion of linseed was given.

respiration \,:a5 affected more easily, and the dog seemed to wish to inspire, but it was not before 12.30 P.M. that inspiration was affected naturally and without assistance. Expiration was not yet possible, and it appeared to become more and more difficult to execute, the ribs once elevated becoming fixed to such a degree that it was necessary to press strongly on the chest wall in order to drive the air out of the lungs. Fortunately this did not last long, and by 12.45 P.M. the inspiration was followed by spontaneous expiration, which, however, was irre~ular and trembling. At I P.M. the dog could inspire and expire without assistance. and when lifted off the table on which it had been put it immediately ran off to the home of its master which was not far distant; once there it drank some milk and appeared quite well. M. Pecus attributed the irregular effects of the anaosthetics administered to some impurity present in the chloral.-Journal de Med. Vet.

THE ETIOLOGY OF ACTINOMYCOSIS.

IN a case of abdominal actinomycosis in the human subject, Ammentorp on opening one of the abscesses found in its centre a pea-sized concretion, in the centre of which there was recognisable a piece of barley awn about 2 centimetres long. The patient admitted that while he had been in the country during the year before he became ill he had often rubbed out barley heads in his hand and eaten the grain. A somewhat similar case had previously been observed in the Clinique at Vienna; III this case also the patient suffered from abdominal actinomycos:s, and a faocal stone which was found in the patient contained at its centre a barley awn.-Zeitsdtrift I fl· u.

THE SYMPTOMS OF RABIES IN SHEEP.

SEVEN sheep belonging to a flock that had been attended by a dog attacked with rabies simultaneously developed symptoms of the disease; in the whole seven the disease began in the same way, namely, the sheep ceased to eat and showed a striking sexual disturbance; both the female and the male ammals followed the other sheep and continually jumped on them; they also bit at the wood, gnawed and scratched themselves at various parts of the skin, stamped with the fore feet, and butted at the other sheep as well as at human beings. The tone of the voice was not altered, but when irritated they occasionally gave a peculiar bleat, such as one usually hears from a ram. Subsequently six of the animals became weak, lay very much, and died after about six days; in the seventh case the disease lasted for ten days.­Zeitschrift I fl· 1l1ld Milell. Hj:f·

THE ORIGIN OF TRICHINOSIS IN PORK.

OWING to the frequent occurrence of trichinosis in the rats to be found about the premises of knackers, the keeping and fattening of swine in such premises has been forbidden in Austria. This law is amply justified by the experience of practical trichina inspectors. N at long ago in Berlin ten pigs that had been fattened on a knacker's premises were found to be the subjects of trichinosis.-Zeit. I fl. u. Milch. Hjog.
