INFECTIOUS ABORTION IN MARES. 
1S7 
As to the relative frequency of occurrence between the 
two forms of cryptorchidy, whether abdominal or inguinal, 
or whether taking place on the right or the left side, the sta¬ 
tistics are very variant. In 1875, Prof. Degive wrote: “ Dur¬ 
ing this time (ten years) we have castrated altogether thirty- 
seven subjects, four of which died with sequelas of the 
operation, and the remaining thirty-three recovered. Of 
these the greatest part had abdominal cryptorchidy ; four, 
only had simple inguinal ectopia.” 
According to Goubaux and Dieriex, the left side is more 
frequently the seat of cryptorchidy than the right. The ob¬ 
servations I have made during the year 1891 give the follow¬ 
ing results: Out of twelve ridglings operated upon, seven 
were abdominal, three were on the right, and four on the left 
side; and five were inguinal, of which two were on the right 
side, and three on the left. Upon data like this it would be 
difficult to establish any satisfactory physiological or anatom¬ 
ical explanation, or to found any rule in respect to the seat of 
these abnormalities. Their appearance seems to be governed 
# by chance or accident.

INFECTIOUS ABORTION IN MARES.* 
By T. J. Turner, B.A., D.Y.S., State Veterinarian of Missouri. 
In response to the Governor’s letter of May 16, 1892, or- - 
dering me to visit the State of Montana, and investigate a 
troublesome malady then affecting brood mares, especially 
those owned by one Marcus Daly, of Riverside, Bitter Root 
Valley, Montana, I immediately started on the trip, and ar¬ 
rived at the Daly ranch on May 24th. An investigation was 
begun in a few days, which required about four weeks to 
consummate. The following is my report upon this subject, 
containing a history of the outbreak, its nature, and salient 
points pertaining to the proper management of the trouble, 
should it occur on any farm ; also facts ascertained by experi-
