performed under chloroform. Having drawn out the 
inversion as far as possible, I enclosed the mass in a 
carbolized tight ligature. On the third day the tumour 
came away, and was followed by a slight discharge of 
matter ; a little carbolized glycerine and water was poured 
into the vagina, and nothing further done. The bitch 
manifested no distress or irritation during the presence of 
the ligature, or after sloughing was accomplished, but fed 
and was as lively as usual, and was fit to return home 
within a week. 
ANTI-CONCEPTION OPERATION.* 
Bitches on “ heat” (cestrum) but too frequently go astray, 
and much disappointment, often attended by serious 
pecuniary loss results from connection with some ill-bred 
cur. Not only, in such a case, is a good litter lost, but if 
there be disparity of size, the male being disproportionately 
large, the life of the bitch is often forfeited. On the other 
hand the unfortunate sequel of “throwing back,” or show- 
ing in future litters the stain of the mésalliance, very 
frequently follows, mental impression being in canine 
females exceedingly strong (see section on breeding). [I 
have noticed precisely the same results in the equine species, 
—one notably a bay mare, was served for the first time 
with a'chestnut stallion, and all her future progeny were 
chestnuts, though she was put to different coloured horses.] 
Knowing a bitch “in season” to have gone astray, what 
measure likely to be of any service to prevent breeding can 
be adopted? Only one! and that is syringing out the 
womb with a rather strong solution of alum, using for the 
purpose the human enema pipe with the vaginal tube 
attached. The sooner the operation is performed after 
disconnection the better, and more likely chance of success, 
but even twelve hours afterwards it may prove preventive,
