rectal membrane. In a piece of the latter, i mm. long and 
o. i mm. thick, 1,500 coccidien were counted, calculating from 
this there would be 150,000 to the square millimeter, or 15,.: 
000,000 to the square centimeter. These coccidien are oval, 
and vary in thickness from 0.01 to 0.22 mm. They are hom¬ 
ogeneous, refractive and of double contour. Haemotoxylin 
does not color them. When aniline colors are used, a nucleus 
thrice as large as that of an epethelia cell becomes visible, 
which completely occupies the cell. Also in coccidium ovi¬ 
form e and coccidium perforans, the nucleus very often dis¬ 
appears by becoming the same size as the cells. Zschokke 
did not observe the development of the cells to sporocysts.—

RECTAL POLYPI IN A FOAL. 
In August, we were driven by the owner to see a one- 
year-old foal which for the last few months suffered recur¬ 
rently from colic. This had lately become more intense in 
its attacks, so that in the weeks immediately preceding our 
visit, the animal declined in flesh and general health. Up to 
this time the usual domestic purgative medicines were given 
with beneficial results, and for this reason a veterinarian had 
not been called. The character assumed by the disease in 
the last few days had become more serious. The strongest 
anti-costive agents acted but mildly ; clysters of lukewarm 
soap water only induced the passage of single, hard pellets of 
manure, covered with a whitish croupous coat. 
Status Prczsens .—The colt, clothed in long, lustreless hair, 
was in a badly nourished condition; the countenance heavy, 
and languid generally. Food and drink when held before the 
patient were untouched. When in the stall the animal con. 
tinued unquiet, flexing the neck and observing the abdominal 
sides, now and again reclining. Upon the gluteal region and 
neck, small expanses of perspiration; ears and extremities 
cold ; respiration labored, and to a slight degree increased in 
frequency ; temperature 102.5 0 ; pulse full, and rating 70 per 
minute at the maxillaris artery; visible mucous membranes
