ABSTRACTS FROM EXCHANGES. 
and operation advised. After casting and securing the animal, 
the region was rendered aseptic and with a crucial incision of the 
skin the bone was exposed. Trephining was performed easily 
as the bone was rather softened. When the cut disc of the bone 
was removed a mass of soft flesh was protruding. It was re¬ 
moved, the sinus irrigated with perchloride of mercury solution 
(i in 3,000) and, after closing the opening with carbolized tow, 
the animal was allowed to get up, when breathing was noticed 
to be improved. Recovery followed without event.— {Veter.

Irregular Strangles Treated with Streptococcus 
Vaccine [A. Kevan Murray, M.R.C.V.S .].—Gray gelding, five 
years old, had strangles, with a temperature of 105°. Treated, 
an abscess under the jaw is opened and the horse seems con¬ 
valescent. Two days later the right parotid is swollen and pain¬ 
ful and the right foreleg is also swollen and very stiff. After 
four days the parotid is free from swelling, but the hind legs 
are greatly swollen and painful. The thermometer runs up to 
10 6/4 °. Poultices, fomentations, fever medicines, form the 
treatment. Then came a swelling on the off lumbar region. 
While that of the hind legs subsides, one makes its appearance 
on the near loin. Colicky pains become manifest. It is a general 
infection and the author decides to resort to streptococcus vac- 
. cine. He injected under the skin two tablets (Parke, Davis & 
Co.’s), dissolved in 5 c.c. of sterilized water. Two days after, 
all the swellings were gone; the horse fed well, his temperature 
had come dowfl to 103° and soon to ioi t /2°. Some four days 
after, however, a little relapse seemed to occur; the temperature 
ran up to 104 V2 0 . Another injection of the vaccine cut it short 
and radical recovery soon followed.— {Vet. Rec.) 
Imperforate Hymen in Cattle [L. L. Steele ].—Although 
not common, it seems that this trouble is quite frequently ob¬ 
served in some countries. The author describes one as follows: 
The heifer subject of this showed symptoms of imperforated 
hymen; she had been straining for several days and was suffer¬ 
ing great pain, which had begun soon after copulation. On 
vaginal examination, the hymen could just be touched with the 
middle finger, so that it could not be broken down with the hand. 
A catheter was tried next, but the hymen resisted the pressure, 
and a trocar was necessary to puncture it. When this was done, 
violent uterine contractions were observed and about half a gallon
