Curator of Mollusks,

Dear Dr, Bartsch* 
As I told you the other day in connection 
with the field work planned for Dr. Joseph P. E. Morrison, 
it is desirable for him to have certain familiarity with 
methods of preparation of bird and mammal skins. Such ex¬ 
perience is useful whether one is collecting mollusks or in 
any other field. 
I beg to ask, therefore, that yon let hi® 
take the necessary time in order to perfect himself in methods 
with the help of our taxidermists. If practical)!© I would 
like to have him use a part of each day on this work. I feel 
sure that you will agree as to the importance of this. 
Very truly yours. 
A. lletffiore. 
Assistant Secretary.
