Mr. Reid explained to me that, in response to the questions he and Dr. Wilcox were going to ask me, that actual physiological changes would be transmitted through a small panel unit. The readings would then be tracked on moving graph paper, which he placed beside the machine on the desk. The parallel graphs on the paper would then be correlated and interpreted by Mr. Reid, with the "expert" assistance of Dr. Wilcox, to determine whether or not I was lying.
