The Fluids of the Inner Ear. 



The perilymph and endolymph are alkaline fluids which, besides 

 salts, contain in the same amounts as in transudations traces of 

 albumin, and in certain animals (torsk) also mucin. The quantity 

 of mucin is greater in the perilymph than in the endolymph. 



Otoliths contain 745-795 p. m. inorganic substance which con- 

 sists chiefly of crystallized calcium carbonate. The organic sub- 

 stance is very like mucin.
