Q. I should think this letter would refresh your memory, Herr Professor, particularly in view of the Ding diary, which has an entry shortly following the date on this letter where Ding carries out his experiments with the Bucharest vaccine among others, and says in the diary that the vaccine was obtained from you; and Mrugowsky in this letter asked you to send him the vaccines which you have mentioned in your previous letter. There’s really no doubt about it, is there, Professor?

A. This possibly becomes apparent.

Q. And was this person Olzscha mentioned in the letter? Was he to assist in Buchenwald?

A. He was to be used in the hygiene service. Since he particularly dealt with entomological questions, I asked that he should work on these questions there.

Q. You got a report from Ding, too, on these experiments testing the Bucharest vaccine, didn’t you, Professor?

A. I cannot remember that, and I already told you once that had I received any such report, I would have drawn the conclusions from it; and since I did not do that, I think it is improbable that I received such a report.

Q. In view of this letter, Doctor, do you want to go back and change your testimony about the Copenhagen vaccine? Didn’t you also suggest those experiments, and didn’t you also supply the Copenhagen vaccine for the experiments in Buchenwald?

A. No. I have no intention of doing that.

Q. Well, in that event I will ask that Document NO-1186 be passed up to you, and this will be marked as Prosecution Exhibit 492 for identification. Will you read this letter aloud please?

A. “Oberstarzt Professor Rose
