Dear Miss Day: 
I wonder if you can give me the information necessary in order to get some 
of the thin transparent adhesive cloth (perhaps silk} that 1 saw Miss Bryant 
using to mount some of the Dev/ England Club specimens two or three months ago. 
I would particularly like to know just what it is called and of whom it is 
purchased, as well as the price. 
For reply 1 an enclosing a franked envelope which will require no postage. 
Very truly, Q
