Dear Sir:
I have the honor to acknowledge the receipt of the two very valuable publications wish you have so kindly sent for the Library of the commission, the titles of which are:
“Natürliche Schöpfungs-Geschichte”, Berlin, 1889.
“Report on the deep-sea Keratosa.”
It gives me great pleasure to inform you that a publication entitled „Fur-Seal and other fisheries of Alaska” will be sent you today trough the International Exchange Bureau of the Smithsonian Institution, and it is hoped that the book will reach you safely in the due course of time.
Yours very respectfully,
M. McDonald
Commissioner.
