Dear Comrade Brandt:
For the reason that Professor Dr. Hirt has in the meantime become seriously ill, I regret that I have been unable to submit any sooner Dr. Hirt’s report which you requested in your letter of 29 December 1941, Journal No. AR/493/37. He was stricken with pulmonary hemorrhages, the diagnosis was “cystlung”, so at least it is not TB. In addition to that he suffered from circulatory asthenia. At present he is still in the hospital, but hopes that the doctor will release him soon so that he can, at least to a limited degree, resume his work. Due to those circumstances Professor Hirt was able to furnish only a preliminary report which, however, I still should like to submit to your attention. The report concerns—
1. His research in the field of microscopy of living tissues, the discovery of a new method of examination, and the construction of a new research microscope, and
2. a proposal for securing skulls of Jewish-Bolshevik Commissars.
As a supplement to report 1, some special publications are attached; of which the two parties from the “Zeiss Nachrichten” #10 (Vol. II) and 1-5 (Vol. III) facilitate most rapid general orientation, whereas other publications deal with difficult, individual scientific studies.
Sincerely yours
Heil Hitler!
