D.--Done!

F.--You have won the wager.

FOOL.--I once read the report of an actual conversation upon a
scientific subject between a fool and a physician.

DOCTOR.--Indeed! That sort of conversation commonly takes place
between fools only.

F.--The reporter had chosen to confound orthography: he spelt fool
"phool," and physician "fysician." What the fool said was, therefore,
preceded by "PH;" the remarks of the physician were indicated by the
letter "F."

D.--This must have been very confusing.

F.--It was. But no one discovered that any liberties had been taken
with orthography.

D.--You tumour!

FOOL.--Suppose you had amongst your menials an ailing oyster?

DOCTOR.--Oysters do not ail.

F.--I have heard that the pearl is the result of a disease.
