ith his experiment?

What would Apeman do, how would he behave, when the white body of
Bentley was well again? Would that body grow well faster when guided
by an ape's brain than when a human brain was in command? Certainly
Caleb Barter must have listed all these questions and hundreds of
others which had not as yet occurred to Bentley. If he had he would
not transfer the two intelligences back to their proper places until
all of his questions were answered to his satisfaction. Bentley
himself must somehow force an answer to some of them.

To do this he must try to guess what sort of questions Barter would
have listed, and try to work out their answers--assuming all the time
that Barter, from some undiscovered coign of vantage would be watching
for the answers he hoped his experiment would provide.

Bentley arrived at a decision. Ellen must long since have become
numbed to the horror which encompassed her. Bentley knew that a human
brain could stand only so much, beyond which it was no longer
surprised or horrified. He guessed, noting the pale face of his
beloved, that Ellen had well nigh reached that stage.

He decided to take a tremendous risk with her sanity, hoping thereby
to do his part in working out the details of Barter's experiment.

The sun was creeping into the west when the roving apes came to pause
in a sort of clearing. Some of them curled up in sleep. The she who
carried Apeman squatted with Apeman in her arms, and licked his wounds
again.

That Apeman was recovering was plainly evident, and when he saw it
filled Bentley with an odd mixture of thankfulness and revulsion.
Apeman was essentially an ape. With all his strength back he would
revert to type, and what if he forced the body of Bentley to do
horrible things that Ellen would never be able to forget or
condone--even when she at last knew the truth? What if Apeman
selected, for example, a mate--from among the hairy she's? For Apeman
that would be natural, for Bentley horrible.

Yet it might easily transpire. Apeman might relinquish the white she
to a successful rival--which he would regard Manape as being--and
content himself with a choice from the ape she's. Somehow that unholy
thing must not happen. That was up to Manape-Bentley.

Or, with his strength fully returned, Apeman might again desire Ellen,
and force the issue with Manape for her possession--which seemed
equally horrible to the brain of
