Saint Bartholomew's Hospital reports . Tig. I. 2o8 On the Breath Sounds of Health and Disease. The artificial thorax with which most of tlie experiments weremade is represented in tig. i. The glass-sided chamber A, fixedupon a firm wooden bench, communicated through the smoothliole K with a second chamber C. Tlie sides of the chamber Cwere made of flexible india-rubber cloth, like the sides of a pairof bellows. The top of the bellows was fixed air-tight to tliebench round the hole leading into the upper chamber A, and thebottom of the bellows was attached to the handle D, moving on aiiinge at E ; at the bottom of the bellows was a tap F. The hole. Fig. 3- H in the roof of the chamber A was intended to admit thecollapsed lung of a calf or sheep. The tube of the flexible stetho-scope L and the tap I also passed through the roof. The innerend of the stethoscope was covered with a piece of bladder to pre-vent the escape of air or water from the chamber. In order to place a lung, or pair of lungs, in the chamber forexperiment, the bronchus or trachea was passed between the twoparts of the sliding frame, flg. 2, and the parts brought togetherso that the bronchus lay without pressure in the hole formed bythe two notches in the frame at N. A lung placed in the frame On the Breath Sounds of Health and Disease. 209 is represented in fig. 3. The interval between the bronchus andthe sides of the hole N was stopped uj) by wrapping some towdipped in a strong solution of gelatine around the bronchus. Thegelatine, when solidified, adhered firmly to the frame and bronchus,and made a perfectly air-tight joint. The two parts of the frameshut upon
