it will be a session fruitful of good work. Botli those who come 
here to describe the results of research, and those who listen, will 
feel an intellectual stimulus, and they will have that craving, not 
only for a knowledge of facts but for a knowledge of causes, which, 
paradoxically, is at once one of the most satisfying and the most 
unsatisfying of all human feelings. Having reached one explana- 
tion, there is, for the moment, a thrill of satisfaction, but this soon 
passes off when we contemplate new problems and new difficulties 
to be overcome. 
Postscript . — With reference to the statement on p. 193 regarding 
the deaf, Dr M‘Kendrick read a communication he had received 
from Dr James Kerr Love, Glasgow, regarding the results of an 
experiment with four deaf-mutes, two boys and two girls, made in 
the Physiological Laboratory of the University of Glasgow, on 5th 
December. The children came from the Deaf and Dumb Institu- 
tion of Glasgow, and they were accompanied by Dr Love, who 
takes a great interest in deaf mutes, and by Mr Welch and Mr 
Haycock, both masters in the institution. Dr M ‘Kendrick car- 
ried out the experiment. One girl, aged 17, who has been quite 
deaf since she was 11 years of age, said that the sensation she 
felt when the fingers were immersed in the salt solution was 
music , and that the feeling recalled something to her memory. 
She had accurate perception of the rhythm of the music played by 
the phonograph. The other three also experienced rhythm, and 
nodded their heads in time to the music. A young lady, deaf from 
her birth, examined by Dr MTvendrick on 4th December, wrote 
that she had a sensation like the purring of a cat, with the “purrs ” 
long and short, and strong and weak. She also compared it to the 
sensation of having a musical box in her hand.
