REPORTS OF CASES.

Scrapings were made from the walls of the abscess, and 
smeared on cover glasses, and then stained for the bacilli of tuber¬ 
culosis, which I found in large numbers under the microscope. 
In places there were clumps of bacilli, ten or twelve in number. 
Cover glass preparations were also made from the liver, but 
revealed no bacilli or signs of tubercle ; they contained, however, 
a large number of fat cells. 
Owing to lack of time, no sections have been cut for examin¬ 
ation from either lungs or liver. 
Excepting the liver, the abdominal viscera appeared healthy. 
I regret to say that I did not open the stomach or intestines, 
but they showed no outward signs of disease. This appears to 
be a case of inhalation tuberculosis, rather than one of ingestion, 
but the bacilli no doubt gained access to the respiratory apparatus 
as a result of the dog’s filthy habits. 
We often hear stories of cats and dogs being kept as pets by 
consumptives, pining away and dying, but we do not often have 
a case recorded backed up by absolute proofs, where a post-mor¬ 
tem is held on the animal, and the bacilli found as final evidence 
of the disease. 
ATRESIA ANI. 
By J. Minchin, V.S. 
No doubt you will be somewhat surprised to receive this from 
a stranger to you, but I hope you will give it your considera¬ 
tion, and let me know if there is any case or cases similar in the 
American record. I was called to see a colt Tuesday last, 
foaled Sunday; was all right apparently till the afternoon, when 
dullness appeared. On Monday got worse, would not nurse, and 
towards night would paw and try to evacuate in the usual way 
but without success. To my surprise I found a total occlusion 
of the anus which was not discovered before. I made an incision 
where the cul-de-sac was visible and extracted several hard pellets 
of the meconium, which gave him instant relief. Not been satis¬ 
fied I made a transverse incision when the struggle caused it to 
expel quite a quantity more ; then I trimmed the wound and 
made what to me was a good opening; put a pledget well satu-
