Dear Ratibor: 
I was in Buffalo, New York the middle of October 
for meetings of the American Ornithologists’ Union where I saw 
Dr. Hartman who gave a paper on the adrenal glands of birds 
and told of the work in Panama. He and I had a good talk and 
frequently mentioned you. 
In your letter to me you stated that you would like 
to have any comments relative to the preparation of the monkey 
skins and skulls, forwarded by Dr. Clark, that you have prepared. 
Dr. David Johnson, Curator of Mammals, says that the skins have 
been well handled and that they appear to be in proper condition 
for tanning. I may explain that with animals this size, we have 
them tanned as this allows them to be handled readily in study 
and also does not require as much space in storage in the collec¬ 
tions as when the skins are stuffed. The skulls that have been 
forwarded are in good shape and will clean up without trouble. 
The data with the specimens has been adequate though 
if practicable, we would prefer having the measurements in milli¬ 
meters. You will recall how Perrygo and I took them from the 
few specimens that we prepared when you were with us. I hope 
that you will be able to continue this work as the specimens 
are highly valuable here in the National Museum. 
Mr. Graf has told me of his meeting you at the 
Gorgas Laboratory and of the work that you were doing now with 
Major Hertig. I am sure that you will find this interesting and 
pleased that you have this opportunity for scientific work. I 
hope to see Dr. Clark when he is up here in Washington at the end 
of this month.
