Dr. Davy’s observations and experiments , &c. 497 
tense and tympanitic. The right lobe of the liver was pressed 
into the epigastrium, and rested on a portion of the stomach 
and duodenum and a part of the transverse colon. Owing to 
the pressure of the liver, the pyloric portion of the stomach 
was removed from its natural situation to the left iliac region, 
where it rested on the upper part of the sigmoid flexure of the 
colon ; and, owing to the same pressure, the small intestines 
generally were driven downwards, and more or less dis- 
placed. 
The body was put into a bath, and a. small opening was 
made, under water, with a scalpel, into that part of the right 
pleura, best adapted by situation to allow the escape of air. 
Air issued out in abundance : 212 cubic inches were collected 
in receivers, and about 13 cubic inches escaped, making 
altogether the enormous volume of 225 cubic inches. The 
air collected was set aside for examination, and the body 
being replaced on the table, a portion of the ribs was removed 
from the right side to admit of the examination of the chest, 
the water that had rushed in to supply the place of the air 
having been carefully taken out and preserved. 
The inner surface of the right pleura was covered with a 
thin layer of coagulable lymph.. The right lung was exceed- 
ingly compressed : it adhered closely to the upper part of the 
pericardium, and loosely to the posterior part of the chest 
(about the sixth and seventh ribs) by a few strong bands. 
On inflating the lungs with a double bellows through an 
opening into the trachea, the right lung became much ex- 
panded, and air was found to pass freely from the lung into 
the pleura through an ulcerated opening in the upper part of 
the superior lobe.
