ABSTRACTS FROM EXCHANGES. 
The Best Position for Incision of the Abdomen in 
Oophorectomy of the Cat [Prof. F. Hobday, F.R.C.V.S .].— 
The author changing his opinion as advanced in his work on 
canine and feline surgery, after performing the operation on 
some ioo female cats, recommends that the higher flank incision 
be resorted to, as far the best of any other for the opening of the 
abdomen. This is based on two reasons: “ first, because the cat, 
being an animal who' (after an operation) has the habit of sit¬ 
ting quietly in a huddled-up position, there is less likelihood of 
adhesion between the fresh wound and either omentum or intes¬ 
tine; and secondly, because in the event of the patient suddenly 
becoming frightened and jumping a height to the floor, there is 
less likelihood of protrusion of the intestine.”— (Ibid.) 
Bony Tumor of the Maxilla [/. P. Heyes, F.R.C.V.S .].— 
Two-year-old filly has on the outer side of the left lower maxil¬ 
lary bone, opposite the third lower molar, a painful, hard swell¬ 
ing. Simple remedies were first applied and the growth enlarged, 
interfering with mastication. When the temporary molar was 
shed, the tumor was readily apparent in the mouth, and it had 
grown, extended to the margin of the masseter muscle and the 
lower border of the maxillary ramus. Firing and biniodide 
blister were resorted to. Acvinomycosis being suggested by the 
presence of small pustules bursting and discharging yellow pus, 
microscopical examination was made and proved negative, 
staphylococci being only detected. Finally surgical interference 
was decided, the animal secured and chloroformed. A large piece 
of the growth was removed and it was then found that within 
this bony tumor there was a sharply defind nucleus of more com¬ 
pact material, probably a perverted developed third permanent 
molar, which rested in a cavity communicating with the mouth 
through the alveoli of the temporary molar. Three days after 
this operation a diffuse swelling appeared on the scapular region 
of the near fore leg with great febrile manifestations; and the 
next day a similar swelling made its appearance in the left lumbar 
region. Pus soon made its appearance and microscopically ex¬ 
amined showed staphylococci. An autogenous vaccine was pre¬ 
pared and injected hypodermically twice in 24 hours. Soon after 
the symptoms improved and one week after the injection the 
mare was entering in convalescence, although it was only after 
seven weeks that the cavity of the jaw was closed.— (Vet Rec¬
