Q. When after December of 1939 or January of 1940 was it that you again witnessed a euthanasia procedure?
A. I should say that during 1940 in all the euthanasia institutions existing at that time I personally assured myself once or twice that the euthanasia was being correctly carried out. But I think I recollect that the Hadamar Institute was only set up in 1941 and in that year I did not witness euthanasia being carried out, so that this would eliminate the Hadamar Institute.
Q. The Institute at Hadamar, I think you said there were five other stations?
A. Yes. There were six altogether.
Q. So that during the year 1940, you assured yourself that each of the five stations on perhaps one, two or perhaps more visits that the procedure insisted upon by Bouhler was being carried out in a humane manner, in a painless manner by carbon monoxide?
A. Completely imperceptible.
Q. And now who were the people—let me put it this way—the first time at Brandenburg there were four people, all men?
A. Yes.
Q. Now, can you remember on your subsequent visits in 1940 to the other euthanasia stations who the people were, men or women?
A. Both, sometimes men and sometimes women.
