New Haven, Conn., October 29, 1891.

Prof. J. Kost, D.D.,

Dear Sir: -

Your letter of September 23 came during my absence, or I should have sooner written in reply. I write now to say, that it will give me great pleasure to do what I can to increase your interest in the National Museum, and to reciprocate ~~in any way~~ for the favors we receive from you.

I did not understand from your letter clearly what privileges you would like in the National Museum, but the contributors to its collections, especially those who make important gifts, certainly ought to be favored in this respect, and I think this is in accordance with the traditions of the museum, although I have only quite recently taken any part in its management.

When I see you, which I hope will be very soon, I will be glad to talk the matter over fully with you.

I am glad you are to continue your researches in Florida this winter under the auspices of the U. S. Geological Survey.

Yours, very truly.

Very dear Sir—

I have the honor to acknowledge the receipt of your kind reply to mine of 28 Sept. Your exp. of cause of death is satisfactory.

All I desire to ask for in my letter was to know if casts might be taken by careful and trustworthy hands, of important specimens that might be accessible for such object. Not meaning any mounted specimens or such as would take injury: and if so, whether the liberty of crediting such casts to the original in the Nat. Museum would be allowed. I am interested in the above named Co., and have promised to allow costs to be taken from any of the specimens obtained by me in the State Geol. Survey of Florida, which I possess. These same specimens, including a Mastodon (rather complete) and parts
