Down, January 7th [1867].
Very many thanks for your letter, which has told me exactly what I wanted to know.

I shall give up all thoughts of trying to get the book (197/1.

Hackel's "Generelle Morphologie," 1866.

See "Life and Letters," III., pages 67, 68.) translated, for I am well convinced that it would be hopeless without too great an outlay.

I much regret this, as I should think the work would be useful, and I am sure it would be to me, as I shall never be able to wade through more than here and there a page of the original.
