Lacharrière has an article on this subject in the Annales des Maladies de L' Oreille, du Larynx, etc. He refers first to the influence which this tinnitus aurium exerts on the minds of many patients, giving melancholia to many and even causing suicide. If proper attention be given to the recital by patients of the character of these sounds, they will be found to represent a certain number of types which preserve absolutely distinct characteristics. These are some¬ times vague sounds like that

A second type is that of rustling, like the air stirring leaves-or more marked, like the escape of a jet of steam. A third type is that of musical sounds-approaching in character sometimes those of the preceding ones, but always having a musical tone, such as noises analo¬ gous to musical instruments, to the striking of metal plates, to the sound of bells, with the airs which one has heard constantly repeating themselves. The fourth type is that in which the subjective sensation presents pulsatile beatings, in two forms, one subject¬ ive, properly speaking, the other pseudo-subjective, in which the physician and patient both perceive the sound. These sounds have been classified as follows : i. Sounds characteristic of occlusion of the nat¬ ural passages, the auditory canal and the Eustachian tube.
