Q. Well, a man of your intelligence must have some idea about the size of these rooms. The assertion “normal size” doesn’t mean anything in particular.

A. By that I mean the size of the normal room in a normal house. I didn’t mean an assembly room or a cell either. I meant a room, but I can’t tell you the exact size because I really don’t know it. It might have been 4 × 5 meters, or 5 × 6 meters, or 3½ × 4½, but I really don’t know. I didn’t pay much attention to it.

Q. Have you ever visited a concentration camp or a military camp of any kind?

A. I visited a concentration camp, and I was once in a military camp as a soldier.

Q. Have you ever seen a shower room or shower bath built into a camp of that kind where the inmates of concentration camps, or where soldiers in a military barracks, can take showers?

A. Yes, I have. In my own barracks.

Q. And would you say that this euthanasia room at the various institutions was about that dimension?

A. I think it was much smaller.

Q. Well, perhaps we can get at it this way. I thought perhaps you knew something about the mechanical construction that I supposed everybody knew something about. This room of yours that you talk about, how many people would it accommodate?

A. Yesterday I said that according to my estimate it might have been twenty-five or thirty people.
