Pulmonary Emphysema—Its Treatment. —Mr. G. Gen- 
dens relates the good results he has obtained in tw^o cases of this 
affection, where the symptoms were of such severity that the 
animal was entirely unfit and unable to work. After using the 
old treatment of progressive doses of arsenious acid without any 
good result, he had recourse to the preparations so frequently 
used by the advocates of dosimetric medicine, and thus 
administered twice a day a pint of beer containing three centi¬ 
grammes of arseniate of strychnia, twenty-five centigrammes of 
arseniate of iron, two grammes of iodide of potassium. With this 
he recommended good hygienic measures and repeated frictions 
on the body. The improvement was quite marked in a week, 
and in two months recovery was complete.— (Annales de Medec.

castor oil administered. Six days later patient died in great

mass of adipose tissue suspended in the mesentery of small intes¬ 
tines, and weighed three and a quarter drams. No abnormal 
changes in any other organs except a number of small ulcera¬

P7'of. W. L. Willia77is, Ithaca, N. ¥.] . —The author narrates that 
in January, 1896, he attended a cow for tympany of moderate 
character, accompanied by painful respirations, grunting during 
expiration, with general stiffness and disinclination to move, 
which led him to suspect the ingestion of a pointed foreign 
body. After puncturing rumen, saline purgatives and carmina¬ 
tives were given, followed by apparent recovery. In four weeks 
he was again called, when the following symptoms presented 
themselves : Dullness, stiff, disinclined to move, feverish, dry 
muzzle, inappetence, tumultuous pulse (intermittent and irregu¬ 
lar), with abnormal pericardial sounds. Referring to former
