[22] There are no general or organized movements on foot for the prevention of deafness as there are for the prevention of blindness. This is perhaps chiefly because there are believed to be nothing like so many preventable cases of the one as of the other, so much of blindness being due to diseases that might have been avoided without great difficulty, and to accidents and other injuries to the eye.
[23] It has been estimated that three-fourths of deafness from primary ear diseases, and one-half from infectious diseases, is preventable. See Proceedings of International Otological Congress, loc. cit.; Volta Review, xiv., 1912, pp. 251, 348.

[27] The possibilities, for instance, in the use of antitoxins and vaccines in certain diseases are just beginning to be known, and some results as affect deafness may be expected from such operations.
[28] In 1909 a special committee in regard to the prevention of deafness was created by the Otological Section of the American Medical Association, and in 1910 both by the American Laryngological, Rhinological and Otological Society and by the American Otological Society.
