[22] I owe to the kindness of M. Chauman, of St. Petersburg, excellent photographs of this man and his son, both of whom have since been exhibited in Paris and London.

[23] These statements are taken from Mr. Sedgwick in the ‘Medico-Chirurg. Review,’ July, 1861, p. 198; April, 1863, pp. 455 and 458. Liebreich is quoted by Professor Devay, in his ‘Mariages Consanguins,’ 1862, p. 116.

Mr. Lawson Tait states (‘Nature,’ 1873, p. 323) that only male cats are thus affected; but this must be a hasty generalisation. The first case recorded in England by Mr. Bree related to a female, and Mr. Fox informs me that he has bred kittens from a white female with blue eyes, which was completely deaf; he has also observed other females in the same condition.
