[54] From p. 134. It has also been computed by Dr. Fay from his data that of 5,455 married deaf persons, 300, or 5.5 per cent, have deaf offspring. _Annals_, lii., 1907, p. 253.
[55] The proportions for the general population are hardly over 0.3 per cent and 0.05 per cent respectively.
[56] The proportion of the married deaf who are married to deaf partners is found by Dr. Fay to be 72.5 per cent, and of those married to hearing partners, 20 per cent, there being no information for the remaining 7.5 per cent. The census returns, however, give the respective proportions as 51.3 per cent and 48.7 per cent.

[58] No statutory action seems ever to have been taken in the matter. In Connecticut, however, in 1895 when a law (Laws, ch. 325) was enacted forbidding the marriage of the feeble-minded and epileptic, a provision respecting the congenitally deaf and blind came near being included. _Annals_, xl., 1895, p. 310.

Report on Insane, Feeble-minded, Deaf and Dumb and Blind, 1895, pp. 108ff., 684; Special Reports, 1906, p. 122. The ages of the deaf were reported less fully in 1880 than in 1890, and less fully in 1890 than in 1900; and if we take the numbers of those whose ages were reported in these three censuses, we have the following table, showing the proportion of the congenitally deaf.
