SUBJECT: Specimens of mammals prepared by Ratibor Hartmann in Panama. 
The specimens prepared by Ratibor ife.rtm.ann for nr. Herbert 0# Cicto.k are , 
flat dried skins accompanied by skulls® The skins have been well handled and 
seem to be in proper condition for tanning, and the skulls are in good shape® 
. 
It iflTouId be of some advantage to us to have labels with the data as. to 
locality, date, collector, and measurements (preferably in millimeters) attached 
to each specimen. Dr. Clark has been furnishing this material on separate data 
sheets. We would be glad to furnish regular Museum labels and skull tags for 
this purpose. 
The material that Dr. Clark has been sending is valuable for the collection. 
If Ratibor Hartmann is to be kept on the Gorgas Laboratoiy staff ana has time to 
devote to this work, I hope that their program can be extended to include the 
smaller mammals. In a recent letter, Dr. Clark stated that he would be in Washington 
for the annual meeting of the Gorgas Memorial Institute, scheduled for the lasu 
Monday in November, and offered to obtain an invitation for a member of our staff 
to attend the meeting if we so desire. He is apparently quite willing to continue 
sending us specimens.
