Sir,

I take the liberty of sending to you, here enclosed, an Essay “on the relation of Surgery to natural sciences” by professor Czerny, of the University of Freiburg, Baden, Germany.¹

In the course of his essay the author speaks of the changes in the structure of the epithelium of mucous membrances ingrafted on superficial wounds, (pg. 13 & 14) and (pg. 15) he applies the Darwinian principles to pathological processes in the organism. Thinking that the essay might have some interest for you, I beg to present you a copy in my friend’s name.

At the same time, I beg to recommend to your attention a German work which, being little known at the present time, may have escaped your notice. It is the:

Kranken-Physiognomik

by

D^r. K. H. Baumgärtner,

late professor of the university of Freiburg (Baden)²

The work is accompanied by a large Atlas, containing a great number of excellent illustrations. There is a copy of this work & of the Atlas in the British Museum. I believe it is the first edition of 1839. There was another edition in 1841. The book is to be found in the Museum under the pressmark number 781. k.9. and the Atlas under number 550. g.21.³

I am, | Sir, | very respectfully yours | Ch. H. Schaible, M.D., Ph.D.

Ch. Darwin Esq. M.A., F.R.S. | etc. etc.. etc.
