EXTRACTS FROM EXCHANGES. 
merits, material for dressing, ligatures, and so on, the animal 
placed under chloroform was operated on, the manipulations 
being divided into four steps. In the first the skin being disin¬ 
fected, a longitudinal incision was made on the skin over the 
most prominent part of the tumor so as to expose the hernial 
sac, which was raised with forceps. Then the hernia was re¬ 
duced by returning the contents into the abdominal cavity. In 
the second step, the sac was opened, the testicle taken hold of 
and amputated, after a solid silk ligature had been applied on 
the peduncle which was formed by the gubernaculum and the 
spermatic blood vessels. The stump, well dried and disinfected, 
was returned in the abdomen. The sac was then carefully sep¬ 
arated from its external attachment and when the dartos ap¬ 
peared free, another strong ligature was applied over it, as high 
as possible, the sac below excised and the stump pushed back 
after disinfection. The inguinal opening was then closed in 
the third step of the operation with continuous suture of catgut 
quite thick. In the fourth step the skin was closed with sepa¬ 
rated stitches near to each other. A triangular bandage kept 
an antiseptic dressing over the wound. Operated on the 13th 
of August, the wound of the right side was entirely healed on 
the 30th, the left required a few days longer. This result was 
certainly very good and the modus operandi applied to animals 
of larger size and older could certainly do as well as the old 
method of closing the sac with clams. The author suggests in 
those cases, after the suture of the inguinal opening, in the sew- 
ing of the external ring using a needle slightly curved and in¬ 
volving only the aponeurosis of the great oblique.— (Rec. de

An EpidEmy of Horse-pox [By Dr.Moreau \.—The author 
has observed a very interesting epidemy which he reported at 
the Acadeinie de Medecine. The diagnosis had not been made 
in the patient who was first affected ; the disease was limited to 
the dorsal face of the hands and fingers and presented all the 
characters of variola. It seemed that the sick man had a mare, 
which had been recently covered, and had on the vulva 
sores similar to those of the owner. The son having taken 
charge of the mare, while the father was ill, took the disease 
and had a similar eruption on the hands. An inquiry made in 
the town revealed the fact that eight other persons had con¬ 
tracted the same trouble and had similar eruptions in caring for 
mares which had been covered in the same place where an epi- 
zooty of horse-pox had existed and which had also presented on
