"47395," came in rapid succession, to which she replied, perhaps a
little slower than before,

"47395."

"Now, 654726," he said.

"654726," she repeated, I thought with some hesitation.

"Again, 2964375," he shot out.

"269," she hesitated, "73--" she stopped.

It was evident that she had reached the limit.

Kennedy smiled, paid the check and we parted at the door.

"Part of the Binet test, seeing how many digits one can remember.
An adult ought to remember from eight to ten, in any order. But
she has the mentality of a child. That is the queer thing about
her. Chronologically she may be eighteen years or so old. Mentally
she is scarcely more than eight. Mrs. Sutphen was right. They have
made a fiend out of a mere child--a defective who never had a
chance against them."
