Serra\. —Called to attend a horse that exhibited very violent 
pains, he found him attended by an empiric, but presenting 
such symptoms that he informed the owner that the subject 
was dying, and waited only to make the post-mortem. On 
opening the abdomen a large quantity of blood escaped from it. 
The spleen was found the seat of markedly developed varicose 
condition of the splenic vein, which at a given point had given 
way and produced a fatal haemorrhage. The case is exceed¬ 
ingly rare, and according to the author, no similar one has ever 
been recorded.—(// Moderno Zooiatro .) 
Treatment of Purueent Mammitis [By Th. Magnus]. 
—Frequent among cows kept in the fields, this disease is ac¬ 
companied with loss of flesh, which is very detrimental to those 
animals. The diseased process increases from the difficulty of 
rational treatment, the animals being kept loose and not seen 
for two or three days. To facilitate the escape of pus, the 
author has resorted, with success, to a treatment which has but 
little objections, the loss of the milky secretion being of second¬ 
ary consideration in animals which are raised for beef. He 
amputates the teat, at its base, and opens freely the galactoferus 
sinuses. There is but little haemorrhage, and if it keeps up, it 
is stopped by plugging. Partial amputation is not as successful 
as when the entire teat is cut off. After a while, the swelling 
of the udder subsides and the animal takes on flesh.—( Giorg .

Paraldehide in Veterinary Practice [By Th. Mag¬ 
nus] . —By its chemical properties, paraldehide stands between 
alcohol and ether. Diluted in io parts of water, or mixed with 
glycerine, it has a special odor and acts as an antiseptic, hypnotic 
and slightly diuretic. An animal is put to sleep with it with 
difficulty ; it acts specially on sensitive nerves, less so on motors. 
30 grammes given in capsules will permit the painless operation 
of castration done standing. Another animal which received 
75 grammes was trephined without any pain. The operation 
lasted 15 minutes. The horse exhibited only slight depression 
and wabbling gait afterward, but those disappeared after an 
hour. In a fistula of the withers, where 90 grammes had been 
given, an incision was made 14 inches in length, and two dorsal 
vertebrae scraped without pain. After 15 minutes the odor of 
the drug was detected in the expired air. The author prefers it 
to cocaine when the field of the operation is quite large and the 
manipulations are to last some time .—(La Riforma Veterin .
