seemed incredible to those who are unaware what intellectual
power and activity are occasionally displayed by persons to whom
one sense is shut out. The blind Rumphius, of Holland

, is still
recognized as conspicuous among erudite botanical investigators;
and John Eddy, had his life been protracted, and he given an
exclusive attention to the same kind of studies, might have
secured to himself a permanent place in the catalogue of Ame-
rican botanists.

Make such use of this imperfect letter as you may think fit.

With due consideration, I remain, very respectfully, JOHN W. FRANCIS.
To Colonel S. L. KNAPP.
