Dear Sir: 
I shall be very glad to place all of Professor Copers types of fossil Cetaceans 
in our University collection at your disposal any time you care to come here. We have some 
other materials secured by later collectors that you may also be glad to sea. It will 
give me much pleasure to put it all at your disposal. 
Believe me. 
Very truly yours.
