Q. Herr Professor, I will ask you to testify from your own memory, and if the defense counsel wishes to put your assistant on the stand, they are privileged to do so; but I am interested primarily in knowing what you know about your assistant. Now, you did not know he studied at Heidelberg until he told you just now?
A. I have 40 to 50 young men at the clinic, and it is impossible for me to know of each one where he studied, but I made his acquaintance at the clinic. He is a very industrious and intelligent person and for that reason I asked him to do this work and take some work off my shoulders.
Q. How long has he been working with you?
A. More than a year.
Q. Working with you about a year, and since that time you have conducted these sea-water experiments yourself?
A. We carried them out shortly before Shrove Tuesday.
Q. Of 1947?
