    blood, serum, etc., and the passage of air into them, ex- cluding therefore all those diseased conditions, by which the entrance of air is prevented; but it indicates nothing more than this. Consonating rales occur when that condition of the lung is present which gives rise to bronchial breathing and bronchophony, and they have therefore the same indica- tions. The dry crepitating rale of Laennec, Skoda retains, but he looks upon it as of little value. He attributes its cause to the distention of the walls of the air-cells, bronchial tubes, and cavities during inspiration, when they have lost their natural contractility, and simply collapse during expiration. The nature of the rales accompanied by metallic tink- ling and amphoric echo is sufficiently indicated by their title. All these rales have more or less a character of moist- ness. The dry sounds heard during respiration, etc., are placed apart from them, and are designated by Skoda as hissings, whistlings, and snorings; they arise for the most part as follows: the snorings in the large bronchial tubes, the whistling in tubes of a lesser diameter, and the hiss- ings in the finest portions of the air-passages; they are produced by the passage of the air through the tubes when narrowed, etc. For their value as diagnostic signs, I refer the reader to Skoda's account of them. Equally simple and philosophic, is his division of the murmurs heard during respiration :— Vesicular breathing. Bronchial breathing. Amphoric echo and metallic tinkling. Indeterminate respiratory murmurs. His division of the thoracic voice is founded on the
