EXTRACTS FROM EXCHANGES. 
drain-tube was introduced, by which the cavity could be washed 
and ridden of a caseous hard mass which was contained in the 
sac. When the discharge had entirely ceased and the drain- 
tube removed, a blister was applied to absorb the thickening 
remaining. The most interesting part of this case is the pres¬ 
ence and escape of pus through the right ear, which indicates 
that the suppuration must have found its way through the 
Eustachian tube into the middle ear and provoked the ulcera¬ 
tion of the membrana tympani.—(// Nnovo Ercolajii.') 
Laryngotomy for Malignant Tumor in a Dog \By 
Dr. Carlo Parascandolo , Prof, at the R. University of Naples ~\. 
—Benignant as well as malignant tumors in the larynx of our 
domestic animals have been recorded by Eanzillotti, Mecke, 
Scruby, Degive, Weber, Fleming, Gwilt, and others. The for¬ 
mer can be removed per mouth sometimes, and again through 
opening of the larynx, when by simple excision, the ecraseur 
or cauterization their extraction can be completed. In this case 
the author had to deal with an epithelioma, characterized by a 
marked swelling as big as a small nut, wich thickening of the 
whole larynx, which in being explored with a rubber tube 
was found the seat of a foreign body. The dog had a hoarse 
bark, coughed frequently, with labored breathing, difficult 
deglutition, and sensitiveness to pressure of the throat. The 
breath was foetid, the saliva, of bad odor, was mixed with blood. 
Examination with the laryngoscope revealed a neoplasm of the 
larynx with an ulceration as large as a ten cent piece localized 
at one point, but with the laryngeal mucous membrane highly 
inflamed. The temperature of the animal was normal. The 
only indication possible was the removal of the larynx. After 
careful measures of general antisepsy practised for several days, 
the animal having received subcutaneous injections of chloral 
and morphine, and separation being made of the crico-tracheal 
ligament, a tracheotomy tube similar to the one used in the 
operation for roaring was introduced in the trachea, and the 
larynx having been exposed, the extrinsic muscles were sepa¬ 
rated from their attachment on the hyoid bone and the car¬ 
tilages, and when the whole cartilaginous frame was isolated it 
was drawn through the cutaneous incision and its section com¬ 
pleted. The floor of the pharynx was closed by stitches unit¬ 
ing the muscles of each side, and the stump of the trachea 
being secured with stitches to the skin, a tracheotomy tube was 
introduced, to be removed and cleaned every day. The animal 
was kept fasting for two days after the operation, then fed by
