Dear Dr. Rascher:

I want to answer your letter with which you sent me your reports. Especially the latest discoveries made in your experiments particularly have interested me. May I now ask you the following:

1. This experiment is to be repeated on other men condemned to death.

2. I would like Dr. Fahrenkamp to be taken into consultation on these experiments.
