Dr. MacNare quite often stood behind Adam where he could watch the rat body through the transparent skull case while Alice engaged Adam's attention. Alice did the same, at times, but she finally refused to do so any more. The sight of Adam the rat, his body held in a net attached to the frame, his head covered by the helmet, his four legs moving independently of one another with little semblance of walking or running motion nor even of coördination, but with swift darting motions and pauses pregnant with meaning, brought back to Alice the old feeling of vague fear, and a tremendous surge of pity for Adam that made her want to cry. Slowly, subtly, Adam's rat body became to Alice a pure brain, and his legs four nerve ganglia. A brain covered with short white fur; and when she took him out of his harness under opiate to bathe him, she bathed him as gently and carefully as any brain surgeon sponging a cortical surface. Once started, Adam's mental development progressed rapidly. Dr. MacNare began making notes again on June 2, 1957, just ten days before the end, and it is to these notes that we go for an insight into Adam's mind. On June 4th Dr. MacNare wrote, "I am of the opinion that Adam will never develop beyond the level of a moron, in the scale of human standards. He would probably make a good factory worker or chauffeur, in a year or two. But he is consciously aware of himself as Adam, he thinks in words and simple sentences with an accurate understanding of their meaning, and he is able to do new things from spoken instructions. There is no question, therefore, but that he has an integrated mind, entirely human in every respect." On June 7th Dr. MacNare wrote, "Something is developing which I hesitate to put down on paper--for a variety of reasons. Creating Adam was a scientific experiment, nothing more than that. Both the premises on which the project was based have been proven: that the principle of verification is the main factor in learned response, and that, given the proper conditions, some animals are capable of abstract symbol systems and therefore of thinking with words to form meaningful concepts. "Nothing more was contemplated in the experiment. I stress this because--Adam is becoming deeply religious--and before any mistaken conclusions are drawn from this I will explain what caused this development. It was an oversight of a type that is bound to happen in any complex project. "Alice's experimental data on the effects of opiates, and especially the data on increasing the dose to offset growing tolerance, were based on observation of the subject alone, without any knowledge of the mental aspects of increased tolerance--which would of course be impossible except with human subjects.
