'Thank you for sending me your publications. I am able to send you some work of my own. I finished last year before I went to Canada an examination of the mammalian spinal cord... The figures of the degenerations were very carefully drawn under camera lucida by myself, but they have been reduced in size too much in the published paper, so as to be very unsatisfactory in my opinion.'
