inhalation pneumonia.

Professor Law suggested that as an experiment on a hopeless 
case we might, in the light of the experiments noted above, at¬ 
tempt the administration of antiseptics by the intra-tracheal 
injection of large volumes of liquids and permit them to be ab¬ 
sorbed from the pulmonary mucosa. We prepared a tepid 
solution consisting of 5 litres of water, 30 grammes sod. chlor. 
and 60 c. c. of the commercial solution of hydrogen peroxide. 
Placing this in an irrigating reservoir at an elevation of ten 
feet above the animal, with the liquid gravitating downward 
through inch rubber tubing and escaping through a ^-inch 
nozzle, the latter was inserted in the tracheal opening and the 
liquid allowed to flow into the trachea in a full stream until 
about one litre had entered, when by an expulsive effort the 
greater part was thrown out through the tracheal openings, 
mouth and nostrils, the liquid emerging frothy and carrying 
with it foetid discharges. As soon as that which had been 
thrown into the trachea was well out the process was quickly 
repeated until within 10 minutes the entire 5 litres of liquid had 
passed into the trachea, the greater part of it having been 
thrown out again, carrying with it much putrid material. 
This was accomplished without apparent distress to the 
patient, causing only a moderate amount of coughing with 
each expulsive effort, and leaving him at the conclusion of the 
ordeal apparently without additional fatigue and with the foetor 
of his breath very effectively diminished, his air passages clean 
and to all appearances the local conditions materially improved. 
The patient died on the following day without our having re¬ 
peated the treatment, and the autopsy showed extensive necrotic 
broncho-pneumonia. 
The only result gathered from the case was the facility with 
which large volumes of liquids could be rapidly introduced into 
the trachea without producing inconvenience to the animal 
worthy of remark, at the same time thoroughly flushing out the 
air passages and measurably deodorizing and disinfecting them. 
Case II. was in all material respects like I operated upon on 
June 4th this year, in the same manner as No. I. by student H.
