BERKELEY STREET,

BOSTON, MASS., Dec. 31, 1889.

Prof. Dr. Ernst Haeckel:

Dear Sir,

I have received your valuable work on „Deep-sea Keratosa“, and beg to acknowledge and thank you for the same. I shall send you in a few days my “Genesis of the Arietidae” which is an attempt at a practical demonstration of evolution.

Very truly yours,

Alpheus Hyatt.
