vices was by beating a bass-drum, which, of course, the blind could hear. But it was curious to observe the deaf awaking from a sound sleep in the morning, or called to chapel and recitation at other hours of the day, by the beating of a bass-drum in the central hall. Those who could not have heard the reverberation of all the artillery in the world felt the vibration of the building produced by the beating of the drum, and obeyed the signal. Some of them dreamed of vibration; none born deaf of hearing.
In further elucidation of the subject, I addressed a letter to Professor J. W. Chickering, Jr., of the National Deaf Mute College at Washington, D. C., and under date of February 3, 1888, received the following:

Upon the above letter I may remark that the single case of the Rev. Job Turner, an educated man, accus-
