It was Saturday , and that was always a good day for him as he could give all of his time to the laboratory . He was especially anxious to have things go well this morning , as he wanted to stop at two o'clock and go down to one of Dr. Parkman 's operations . That end of it was very important and this was to be an especially good operation . He was thinking about Dr. Parkman on the way down ; -- of the man 's splendid surgery . It was a real joy to see him work .
