condition : at one time being softer and lower in tempera- 
ture, at another the reverse. The presence of fluid was 
always evident. On the latter date I made a most careful 
examination, the patient being then considerably reduced 
in flesh. The left tumour was at this time exceedingly 
tense, hot, and larger than it had ever been ; moreover, the 
bitch evinced pain, especially on manipulating it, and had 
not been observed to micturate with her usual frequency. 
I at once determined to explore this particular tumour with 
a fine trochar. This I inserted at the right of the nipple, 
and when withdrawn there came through the canula a full 
stream of hot urine, altogether nearly a breakfast cupful., 
With this evacuation the enlargement entirely disappeared, 
and nothing remained but themammary gland. The other 
tumour also became less, owing, doubtless, to removal of 
the pressure consequent on the distended bladder. All 
doubt now as to the nature of the tumours was at an end. 
It was clearly a case of double rupture; the sac tapped 
contained the greater portion of the bladder, with probably 
a small knuckle of intestine, while the opposite tumour was 
entirely intestinal. The peritoneal rupture on either side— 
which it was previously, notwithstanding careful manipula- 
tion, owing to the size and fulness of the enlargements, 
impossible to detect—could now be distinctly felt. 
The following morning the same state of affairs existed, 
and again I passed the trochar with a similar result, repeat- 
ing the operation for two or three days. In the meantime 
she was prepared for an operation, which I performed on 
the 28th; Mr. C. A. Newnham, surgeon, who kindly 
assisted me, also his son, and several gentlemen who took 
an interest in the case. 
The bitch being put under the influence of chloroform, 
and placed on her back, and the hind parts lifted a little off 
the table to facilitate the reduction of the hernia, I made a 
longitudinal incision to the right of the nipple. On divid- 
ing the sac, intestine alone was visible, and the absence of
