character a« that emanating from the nostrils. Manual explo¬ 
ration revealed a large firm tumor situated between the base of 
the tongue and of the epiglottis. The animal was secured upon 
the operating table, chloroform anaesthesia produced, and trach¬ 
eotomy performed in order to guard against the inhalation of 
blood or other substances during the removal of the tumor. 
The operator, Dr. G. T. Stone, found difficulty in manipulating 
the tumor, and in order to secure more room, staphylotomy, or 
division of the soft palate along its median raphe was per¬ 
formed, which greatly increased the room and facilitated the 
chief operation. The tumor was then removed by ecrasement, 
the mare spaying ecraseur being found very convenient on ac- 9 
count of its length. There was no haemorrhage worthy of 
note. 
The tumor is spherical in form, three inches in diameter, 
tense and fluctuating. After fixing in formalin a perpendicular 
section shows it to be a multilocular retention cyst, the contents 
of which have coagulated firmly and are easily detached from 
the cyst walls. The greater portion of the tumor consists of a 
single cyst about 2X3 inches in diameter with three smaller 
cysts at the base varying from ^ to 1 inch in diameter. When 
the animal had recovered from the anaesthesia the trachea and 
bronchi were freely flushed out with a solution of hydrogen 
peroxide introduced through the tracheotomy tube. 
On January 4 there was moderate febrile reaction after the 
operation, the temperature reaching 103.5^., declining daily 
until on January 8th it had reached 100.8° P. The general ap¬ 
pearance of the patient was immediately benefitted, the cough 
and bronchial discharge abating rapidly. The trachea and 
bronchi were flushed out daily with hydrogen peroxide solution, 
using for each washing 5 liters of water at 37 0 C., to which was 
added 5 grammes sod. chlor. and 60 cc. commercial peroxide 
of hydrogen. 
The patient was discharged January 12, and on January 18 
was returned on account of an abscess at the point where trache¬ 
otomy was performed, the pus collecting between the trachea 
and the sterno-thyro-hyoideus muscle. 
The abscess was opened freely, disinfectants applied and the 
patient returned home. 
Patient returned May 1st because of dyspnoea and showing 
a large, firm swelling 8 to 10 in. long and 5 or 6 in. thick ove*r 
the tracheal wound. This was opened down to the trachea by 
means of a median incision as long as the tumor, and reopening
