Hygiene Institute of the University
Dear Professor:
In connection with my letter of 26 February and your long distance telephone call of 6 March, I must advise you that the Japanese Oberstabsarzt has in the meantime contacted Oberstarzt Professor Dr. Rose of the Luftwaffe Medical Service, and that the latter has promised to secure for him from Strasbourg all the accounts concerning the yellow fever virus experiments which are important to him. Therefore, Oberstartz Dr. Rose will give you further details. I therefore ask that the matter be considered closed between us.
With fraternal esteem and
Heil Hitler!
Respectfully yours
[Signed] Dr. Grunske
Flottenarzt
