    doubtless, crepitation is a very fine mucons rale. Indeed, the main distinction of crepitant from mucous rale, so far as concerns the sounds alone, lies in the shortness or smallness of each cre- pitus, and, what is mostly associated herewith, the large number of crepitations attending each inspiration.^ II, Mucous Rale.—This rale includes all sounds which seem to be due to the passage of air through mucus or other fluids contained in the air passages. The notion received is cer- tainly, for the most part, that of bubbles bursting; sometimes the sound is crackling rather than bubbling in character. Mucous rale is sub-divided into varieties, according to the following considerations :— i. The apparent size of the bubbles ; so small as to approach the crepitant rale (subcrepitant), so large as to deserve the name of gurgling, and and all intermediate sizes, ii. The clearness of the rale : the rale being sometimes more or less obscure,^ on account of weakness of the respiration ; a deeper breath 1 After the example set by P. M. Latham and Watson, the term crepitation is still used by many, so as to include mucous rale. Rale obscur : Laennec: Ausc. med., vol. i. p. 103,
