a comparatively successful systotomy the patient died, exhibiting 
at the post-mortem a prostate as big as two large nuts, with its 
structure still homogeneous but of soft consistency. A second 
case refers to a calcular cystitis , sequella of a prostatic hypertro¬ 
phy. The dog had some difficulty in micturating, due to the 
presence of a calculus in the urethral canal. Relieved several 
times of the same trouble, one day one of the stones was found 
engaged in the bony structure of the penis, which for its re¬ 
moval demanded a complicated urethrotomy, which in the pres¬ 
ence of the uncertainty of permanent relief, decided the owner 
to have the dog destroyed. The bladder was found to contain 
a large sediment and numerous small calculi,—some sixty. The 
prostate was enormous. A third case relates a manifestation of 
perineal hernia produced by a displacement of the urinary 
bladder, which at first can be reduced, but after some time has 
assumed large dimension and imposes for its reduction, the 
puncture of the bladder through the perineum. Cystopexy is 
the only possible chance for a permanent relief,—but during the 
operation the dog dies by hemorrhage, and at the autopsy here 
again a noticeable hypertrophy of the prostate proves to be the 
original cause of the trouble. To conclude, the author relates 
a case of enlarged prostate, complicated with hydronephrosis , 
resulting from the obstacle to micturation due to the abnormal 
gland; it was enormous and containing in its lobes softened 
centres, with colloid but not purulent contents. After con¬ 
sidering the indications of treatment according to the manifes¬ 
tations, Prof. Rienaux speaks favorably of castration, which by 
recent experiments seems to be followed by atrophy of the pros¬ 
tate structure. Other treatments which have found their way 
in human surgery do not appear to be practicable in veterinary.

Accidents Observed in Race Horses. —On account of 
the importation of English thoroughbreds into Belgium and 
their presence on the racing tracks, Mr. F. Hendricsen has had 
opportunity to observe some very interesting cases, a number of 
which he records. Tendinous Distensions .—Under this denomi¬ 
nation he refers to the “ breaking down ” of the English, which 
can involve the laceration of some of the organs of suspension 
back of the cannon, tendons or ligaments, a condition called in 
Belgium the “snapping” of the tendons. The treatment which 
he recommends is either cold or hot water, blisters of mercurial 
ointment, or severe cauterization in lines and intermixed with 
points. A rest of not less than six months is required. Sprain
