Mr. Dr. W. Holland, Director Emeritus of the Carnegie Museum.  Pittsburgh. Penna.



My dear Dr. Holland:



I have just received your interesting pamphlet "Annals of the Carnegie Museum"

with the notes about the Diplodocus you present to our Museum.  Many thanks.



I beg you shall be so kind as to send me your new publications in the future.  Here are nothing new.  I am sad as ever.
