TO DR. E. BROWN-SÉQUARD. F.R.S., &c.

Dear Dr. Brown-Séquard,

I am deeply indebted for your kind permission to dedicate this work to you. I feel assured that its introduction to the Profession under the auspices of the greatest physiologist of the day will secure for it greater consideration, and lead to a closer examination of its contents, than would otherwise have been the case.

With the greatest respect, believe me to be,

Most faithfully yours,
