Professor Neustadt smiled his ironic, exasperating smile.

"The defense stipulates to the facts as stated."

The frontal grid lights on Cyber V flashed furiously; the hum rose to a whine, like a motor accelerating for a steep climb.

Suddenly, all was quiet, and Cyber V spoke in the same soft, pleasant voice:

"There are three cases in modern jurisprudence that have direct bearing on the matter of People vs. Neustadt.

"Best known is the case of People vs. Borth, 201 N.Y., Supp. 47...."

Walhfred Anderson saw the D.A. stiffen to attention as the Cyber repeated the citation given by Professor Neustadt. He felt his own pulse surge with the stir of a faint, indefinable hope.

"There are also the cases of Forsythe vs. State, 6 Ohio, 19, and Murphy vs. U.S., 2d, 85 C.C.A.

"These cases establish precedence for a courtroom demonstration to determine points of material fact.

"Thank you, Gentlemen."
