Rh Bell laid great emphasis upon the influence of educational segregation, especially upon the use of a sign language, with its subjective influence on thought, in bringing about the intermarriage of the deaf. That this is a factor appears from Fay's elaborate records. He classified 7,277 deaf individuals according to the method of education and found that of those who attended boarding schools for the deaf, 86.2 per cent, married deaf mates, while of those who attended day schools, or both day and boarding schools, for the deaf 77.8 per cent, married deaf consorts. In contrast are the records of those who attended no school for the deaf: in this class, 62.4 per cent, married deaf individuals. The difference between 62.4 per cent, and 86.2 per cent, probably indicates roughly the influence of scholastic segregation.

Fay also finds that of the pupils who attended exclusively oral schools 78.2 per cent, married deaf partners, while of those who were educated at schools not exclusively oral, or partly at schools exclusively oral and partly at schools not exclusively oral, somewhat over 86 per cent, of marriages were homogamous for deafness. Perhaps these figures indicate a sensible influence of the method of instruction. Nevertheless, one cannot but be impressed with the intensity of the assortative mating that occurs independent of this factor. With no such isolation 62 per cent, of deaf individuals marry those who are deaf. Considering the intensity of the inheritance of deafness, we see what grave social results may be expected from this tendency.

Apparently unions where both members are deaf are more happy than those where only one is so afflicted. Table IV. gives the best available

records indicating the "success" or "failure" of like and unlike matings. Of course divorce, separation or number of children do not tell the whole tale; they give rather a lower limit to the measure of domestic infelicity.
