He finally rose, bathed and dressed for dinner. But during the meal his mind was in such a turmoil he had trouble keeping himself outwardly calm. For the first time in more years than he could remember he merely toyed with his food ... and he had always been a good trencher-man.
But he had something very important to do tonight, and he would let nothing keep him from it. So he went to the Hellene's library and studied from such books on biology and physiology as he could find, all he could about the brain and the nerves that formed the connecting links between it and the muscles. He studied until the dimming of the lights told him that "day" was over.
He then sent his mind down into the brain of the bulldog, and watched through its eyes until he saw the kennel steward leave for the night. Then Hanlon went down to the kennel deck.
Sitting on the same bench as before, Hanlon sent his mind into that of the white bull. Again he had no trouble attaching a portion of his mind to the dog's brain. A little experimentation soon showed how much of his mind that brain could contain.
Then, from the inside, he studied that brain line by line, muscle and nerve channels and connectors, even more surely than he had been able to do before.
The first thing he learned, and put into practice, was to make the dog sleep, so he wouldn't tire too much. After nearly three hours of intensive study he was convinced he was beginning to know it quite well, although he realized how much there still was for him to learn—how much study and practice he would need.
He then woke the dog, and while still leaving that part of his mind in its brain, scanned the next cage which held a beautiful female Airedale. Into her brain he sent another portion of his mind. Then into the next dog another portion, and on and on until he had detached more than three-quarters of his mind, and was controlling directly eight dogs.
His body felt weak and listless as it sagged on the bench, and he made it lie down there in the semi-darkness. There was, he was afraid at the time, little more than enough mind left in his body to keep the semi-automatic functions going.
It was the most weird sensation imaginable, having portions of his mind in nine places at once—having nine different and distinct viewpoints!
He found he could do, although not too well at first, nine different things at once and the same time, or could make all the bodies he was controlling do the same thing at the same time.
