    the comprehensive bibliography is particularly worthy of mention. ToYNBEE, who paid particular attention to the examination of deaf-mutes during life, and to post- mortem examinations of their organs of hearing, has a special chapter (chap, viii.) upon deaf-mutism in his eminent work on ear-diseases, published in i860 [86]. This contains his numerous observations, and is of lasting value. Finally, mention must be made of the following recent works on deaf-mutism : A.

Lemcke's Die Tmibstunimheit iin Mecklenhurg- Schwerin [210], a most admirable work, the result of a personal examination of all deaf-mutes in Mecklenburg-Schwerin.
