EXTRACTS FROM EXCHANGES.

upper commissure of the ring downwards, and perfect adapta¬ 
tions of the borders obtained. But as some of these had a ten¬ 
dency to cut through the muscular fibres, a second row of su¬ 
tures, less in number, was applied, taking a greater amount of 
tissue on each border. The wound was thoroughly disinfected 
with Van Swieton solution and the skin sewed with separated 
srftures, after amputating a certain amount of superfluous tis¬ 
sue on each border. During the first five days the filly showed 
symptoms which caused fears of the possibility of peritonitis, 
but she recovered from them. On the tenth day the deep 
sutures were removed and the superficial wound was treated an- 
tiseptically. Twenty-eight days after the operation there re¬ 
mained but a small cutaneous sore which gradually dimin¬ 
ished and the little animal was discharged.—( Annales de

Tympanitis of the Guttural Pouches [By Prof. A. 
Degive\. —Referring to a similar case reported in the Annales , 
the author relates two cases which had come under his observa¬ 
tion and treated by him recovered ; after three months in the 
first case and five weeks in the second. From his consideration 
of these cases Prof. Degive is of the opinion that (i) pneuma- 
tose of the guttural ponches is the result of a retention, or pro¬ 
longed gaseous pressure; (2) that the collected gas is most 
generally produced in the cavity, from an alteration in the 
secretion of the mucous membrane ; (3) that the retention of 
gases may depend exclusively upon a special disposition of the 
pharyngeal opening in its normal state. There are three means 
of treatment: (1) Incision of the pouch , which he performs in 
the lower third of the swelling and following the great axis of 
the parotid gland. This must be kept opem at least five weeks. 
(2) Antiseptic injections , which are all good,—tepid solutions be¬ 
ing better than the cold ones. (3) Enlarging of the pharyngeal 
opening , which he considers really useful only in two conditions : 
when there is a marked stricture, accidental or congenital, of 
the guttural orifice, or where recovery has not been obtained 
with the two other methods.—( Annales de Bruxelles.) 
Singular Accident of Spaying in a Cow [By N. Bald ]. 
—In the operation of castration in cows, Prof. Degive has intro¬ 
duced for some time back a modification which consists in the 
application of an elastic ligature on the support of the ovary, 
which is secured against untying by a small glass pearh 
The author had two animals to operate on. In one, with the 
exception of one ovary being torn away before the elastic ring
