    2. Sounds Produced by the Air passing to or fro in Air- tubes, OR in Cavities. f Rhonchus. A harsh, rough, or snoring sound, caused by the passage of the air along the larger bronchial tubes, when the mucous membrane is swollen or covered with viscid mucus, or when the calibre of the tube is diminished from any cause. Sibiius. A hissing or whistling sound produced in the smaller bronchial tubes, under the same circumstances which give rise to rhonchus in the larger ones. Bronchial breathing. A sound resembling that heard on lis- tening over the trachea during respiration. When heard over a part of the chest, normally occupied by healthy lung, it may result from the air-cells of the lung being rendered solid by the accu- P mulation of lymph and serum, tubercle, cancer, &c., and thus rendered a better conductor of the sound which is produced by the air as it passes along the larger bronchial tubes. This sound is often heard in pneumonia, tubercle, or cancer, but it may depend upon the pulmonary tissue being somewhat compressed and forced close to the parietes of the chest, as from the accumu- lation of fluid in the pleural cavity. Cayernous breathing. A loud, harsh sound, produced by air rushing through a tube or dry cavity. Amphoric breathing. The sound produced when air passes l^to or from a narrow orifice into a large cavity containing air. Large crepitation. Large or coarse crepitation. Mucous rales. Moist sounds, produced by bubbles of air passing through tenacious mucus or a viscid secretion in the larger bronchial tubes, or in small cavities. Gurgling. A sound produced by the passage of successive § ] bubbles of air through fluid contained in a tube or in a cavity. Metallic tinkling. Probably caused by the sudden escape of a small bubble of air through fluid, or through a narrow opening into a cavity. It may be produced by moving the patient slightly, ^in a case where fluid and air exist in the pleural cavity. 3. Modified Voice Sounds. Bronchophony. The voice sound modified by resounding in a tube or small cavity just beneath the walls of the chest, or separated from the surface by solid lung, resembling the sound heard by placing the ear a little below one or other stemo-clavi- cular articulation of a healthy person while speaking. u
