ANTISEPTICS IN CHRONIC CATARRH OF THE GUTTURAL POUCHES. 121 
to flow from the lower operation wound. The condition now remained 
at a standstill for a long time, and a lotion of acetate of aluminum was used 
for rinsing the guttural pouch. The wound closed after removal of the 
drainage-tube, but had to be re-opened on April 22nd, because the sac had 
again filled. Washings with permanganate, acetate of aluminum and 1 per 
cent, of corrosive sublimate were without success. The discharge continued, 
though in smaller quantities. On June 9th the patient was cast, and the 
operation wound, especially the upper part, so enlarged that the hand could 
be passed into the pouch and the fingers introduced into the Eustachian tube. 
The finger of the left hand, introduced from the mouth, could also be passed 
into the Eustachian tube, so that both hands met here. The tube appealed 
widely dilated; but it was further laid open with a guarded tenotome, m 
accordance with Bassi and Niebuhr’s suggestions. The sac continued to )e 
washed out, and from time to time painted throughout with a 2 per cent, 
solution of sublimate. But this treatment remained unsuccessful. The 
discharge continued. No marked contraction occurred in. the mucous 
membrane, and the guttural pouch preserved its abnormal size. W hen it 
was seen on June 17th that the horse showed no dyspnoea, even on movement, 
treatment was discontinued, and the animal sent to grass. In December, 
1886, the horse was quite capable of work ; the operative wound was not then 
closed, though it had become smoothed off. The secretion was slight, and the 
guttural pouch markedly smaller. 
This case shows how obstinate the disease may be. Such difficulties 
are to be expected. Where the condition has existed foi a long time, 
and the sac has been much dilated, it cannot, owing to its connection with 
neighbouring parts, readily resume its normal volume. Possibly dila¬ 
tation of the opening of the Eustachian tube produced by the lasting 
discharge also forms an obstacle to healing. 
Thomassen’s case of hydrops of the pouch also showed swelling, slight 
respiratory dyspnoea, and want of appetite. An experimental opening 
was made, and four pints of amber-coloured serum allowed to escape. A 
drainage-tube was inserted, and recovery occurred in three months. 
Cadiot and Dollar describe a case of chronic pharyngitis and catarrh 
of the guttural pouches cured by double hyovertobrotomy. The animal 
was thin, had difficulty in swallowing, showed a muco-purulent discharge 
mixed with fragments of food from both nostrils, and occasionally suffered 
from violent attacks of coughing. Part of the drinking water returned by 
the nostrils. Both guttural pouches were opened and daily irrigated with 
antiseptic solutions for a period of three weeks. Kecovery was almost 
complete in a month. (“ Clinical Veterinary Medicine and Surgery,” p. 885.) 
(7.) TYMPANITES OF THE GUTTURAL POUCH. 
The disease described by French authors, and especially by Vatel 
and Gohier, as guttural tympanites, has been observed repeatedly by 
others. Friebel and Kuhnert found this condition in foals soon after 
birth. It consists in the accumulation of abnormal quantities of air or
