should find the three combined in him."

The landlady here laughed quite heartily, and handed the School-master
an extra strong cup of coffee.

"There is a great deal in what you say," said the Idiot, without a
tremor. "There are very few scientific phenomena that cannot be
demonstrated in one way or another by my poor self. It is the exception
always that proves the rule, and in my case you find a consistent
converse exemplification of all three branches of absent-mindedness."

"He talks well," said the Bibliomaniac, _sotto voce_, to the Minister.

"Yes, especially when he gets hold of large words. I really believe he
reads," replied Mr. Whitechoker.

"I know he does," said the School-master, who had overheard. "I saw him
reading Webster's Dictionary last night. I have noticed, however, that
generally his vocabulary is largely confined to words that come between
the letters A and F, which shows that as yet he has not dipped very

was one of his weak points.

"It's a beastly habit," said the School-master, much relieved at this
turn of the conversation.

"Well, perhaps you are right," returned the Idiot. "People do, as a
rule, prefer to talk of things they know something about, and I don't
blame you, Doctor, for wanting to keep out of a medical discussion. I
only asked my last question because the behavior of the Bibliomaniac and
Mr. Whitechoker and the School-master for some time past has worried me,
and I didn't know but what you might work up a nice little practice
among us. It might not pay, but you'd find the experience valuable, and
I think unique."

"It is a fi
