"Taxicab," said the doctor, and, after an almost imperceptible pause, "road" came the association. All at once I began to see the possibilities.
"Desk." "Pen."
"Pipe." "Smoke."
"Head." After a perceptible pause the answer came uncertainly. "Hair." But the association of ideas would not be denied, for in answer to the next word, which was "ice," he gave "blood," evidently following up the previous word "head."
I found myself gripping the arms of my chair. The dial on the doctor's clock-like instrument was measuring the interval; I could see that now. The doctor took a record of every word and its response. Wardrop's eyes were shifting nervously.
"Hot." "Cold."
"White." "Black."
"Whisky." "Glass," all in less than a second.
"Pearls." A little hesitation, then "box."
"Taxicab" again. "Night."
