    there is an increase in the deaf-mute rate in countries with a large deaf-mute population, while there is a decrease in countries with a comparatively small deaf-mute population. These statements are made with reservation on account of the difference which probably exists between earlier and later statistics. Finally, it must be observed that the deaf-mute rate may vary greatly within the boundaries of each country. For instance the deaf-mute rate varied in Switzerland from 54 (Basel) to 436 (Lucerne) per 100,000 inhabitants, in Alsace-Lorraine from 93 (Lorraine) to 121 (Upper Alsace), in Wiirtemberg from 63 (Donaukreis) to 158 (Jagstkreis), in Sweden from 88 (Kopparbergs Lan) to 167 (Elfsborgs Lan), in Prussia from 92 (HohenzoUern) to 182 (East and West Prussia), in Finland from 92 (Uleaborg Lan) to 103 (Nylands Lan), in Bavaria from 64 (Schwaben) to 141 (Oberfranken), in Ireland from 72 (Leinster) to 90 (Munster), in Denmark from 37 (Maribo) to log (Hjorring), in Saxony from 40 (Dobeln-Meissen) to 98 (Olnitz) and in Italy from 43 (Adriatica) to 131 (Alpina). RACE.—Existing literature throws but little light upon this question; the following is, however, worthy of notice. Hebrews.—It is a known fact that the Hebrew race produces a larger number of blind and idiotic individuals than the European races among which it lives. It seems, also, at least in many places, to produce a comparatively larger number of deaf-mutes. LiEBREicH [87, p. 54] and Kramer [Hartmann, 132,
