Mr. Powell stood up, walked across the concrete floor and took down a
shepherd's crook which was hanging on a peg. Sitting down once more on the
edge of the tank, he began unthinkingly to tap with the butt of the crook the
rhythm of a current popular song.
"Er—please, Stephen," said Dr. Boycott, with a faint smile.
"Oh, sorry."
The large mongrel dog in the tank was continuing to struggle with its front
paws, but so feebly now that its body, from neck to rump, hung almost
vertically in the water. The spaniel-like ears were outspread, floating on
either side of the head like wings, but the eyes were
(20)
submerged and only the black, delicately lyrated nose broke the surface. As
Mr. Powell watched, this too went under, rose again for an instant and then
sank. The body, foreshortened by refraction as it descended, seemed to move
sideways from its former floating position, finally appearing on the bottom of
the tank as an almost flattened mass and disturbing round its sides, as it
settled, little clouds of dirty silt. Dr. Boycott clicked the stopwatch. Mr.
/Powell, looking quickly back to see whether he had noticed the silt (for his
chief was particular about the cleanliness of equipment), made a mental note
to insist to Tyson, the caretaker and head-keeper, that the tank should be
emptied and cleaned tomorrow. Then, allowing for the refraction with the skill
of a certain amount of practice, he plunged in the crook, engaged the dog's
collar and began to drag it to the surface. After a moment, however, he
faltered, dropped the crook and stood up, wincing, while the body subsided
once more to the floor of the tank.
"Christ, it's heavy," he said. "Oh, no, chief, I don't mean it's any heavier
than usual, of course, only I pulled a muscle in my wrist last night and it's
been giving me a spot of gyppo. Never mind, never say die, here goes."
"I'm sorry," said Dr. Boycott. "Let me help you. I wouldn't want you to suffer
avoidably."
Together they pulled on the crook, raised the heavy, pelt-sodden body head-
first, broke the surface tension with a concerted heave and laid the inert dog
on a foam-rubber mattress beside the tank. Here it resembled an enormous,
drowned fly—very black, with a compressed shape something like that of a
raindrop; and smaller than life, on account of a kind of collapse of the limbs
and other excrescences into the central mass of the trunk. Mr. Powell began
resuscitation; and after a little the dog vomited water and commenced to gasp,
though its eyes remained closed.
"Right, that'll do," said Dr. Boycott briskly. "Now the usual tests, please,
Stephen—pulse, blood sample, body temperature, reflexes—the various things
we've been work-iag on—and then plot the graphs. I'll be back in about
minutes. I'm just going over to the Christiaan
(21)
Barnard block to learn what I can about this afternoon's brain surgery work.
And please don't smoke while I'm gone," he added, mildly but firmly. "You'll
appreciate that that could have an effect on results."
"All right to put its muzzle on, chief?" asked Mr. Powell. "Only this one,
seven-three-two, 's been known to be a right sod at times and it might come
round enough to start in on me—sudden-like, you know."
"Yes, there's no objection to that," replied Dr. Boycott, picking up the stop-
watch.
"And the time, chief?" enquired Mr. Powell in a rather sycophantic tone, as
though the time were likely to be something to Dr. Boycott's personal credit.
"Two hours, twenty minutes, fifty-three and two fifths seconds," answered Dr.
Boycott, "Without looking at the papers, I think that's about six and a half
minutes longer than Wednesday's test and about twelve minutes longer than the
test before that. It's rather remarkable how regular the increase apears to
