ODONTOME IN A YOUNG FOAL. 
IO3 
yielding wall prevented further ingress. Thrusting a finger 
through this wall, about pints of a pale reddish-yellow fluid 
gushed out, which at once relieved the dyspnoea. The cyst 
wall, corresponding in general shape to the walls of the maxil¬ 
lary sinus devoid of all partitions (these having been absorbed 
from pressure), was attached at the inferior part only, at about 
the position of the fifth molar follicle. The cyst was drawn 
away in pieces by means of dressing forceps, the operation 
being accompanied by profuse haemorrhage. 
At the most dependent or anterior portion of the sinus 
(which had been much extended beyond the normal size and 
position by the pressure), a free opening was made into the air 
passage into which a good sized aseptic pledget of cotton was 
firmly pushed from the sinus. The sinus was then filled with 
cotton saturated with carbolized oil, with powdered iodoform 
over surface of pledgets. After 24 hours the dressing was 
removed, the parts scrupulously washed and the dressing re¬ 
peated. After 48 hours the plugging of sinus and external 
wound was discontinued, the tampon in opening between sinus 
and nostril being continued two or three days longer to avoid 
adhesion. Aside from tampon, the dressing consisted of pow¬ 
dered iodoform mixed with about equal bulk of powdered 
starch (by which the iodoform is more readily finely divided 
and more equally applied), and applied to sinus by means of a 
small powder bellows. 
Within 5 or 6 days it was seen that the iodoform caused 
large hard incrustations to form within the sinuses, and it was 
replaced with carbolized oil, the openings, both facial and 
between sinuses and nostril, being left free. All secretions 
were discharged through nostril, but at no time were these 
of considerable amount. 
After about 10 days, while all was going along as favorably 
as was at all possible, the foal contracted strangles which 
affected the progress of the case unfavorably. Submaxillary 
abscesses formed and discharged freely, the disease running 
a typical and reasonably severe course.
