By overhearing a conversation, Juan is able to tell the number of
seeds in an orange (melon), and to win a large sum of money from a
neighboring king who has come to bet with hero's father-in-law.

F Hero required to accept another bet, as to the contents of three
jars. (Method as in E,--swimming out to neighboring king's casco and
overhearing conversation.)

G Ejaculation guess as to contents of golden ball (bottle).

H Afraid of being called on for further demonstration of his skill,
hero burns his "magic" book.

These incidents are distributed among the four forms of the story
as follows:--

Version a A1A4C1C3DEG
Version b A1A2BB1C1C2DEG
Version c A1A2BCC2DE(accidentally hears answer)FH
Version d A1A3A4EB

A concluding adventure is sometimes added to version c, "Juan
the Guesser." King and queen of another country visit palace of
Juan's father-in-law and want their newly-born child baptized. Juan
is selected to be godfather. When called upon to sign the baptism
certificate, he instantly dies of shame, pen in hand: he cannot write
even his own name.

A connection between our story and Europe at once suggests
itself. "Dr. Knowall" (Grimm, No. 98) is perhaps the best-known,
though by no means the fullest, Western version. Bolte and Polivka
(2 [1915] : 402) give the skeleton of the cycle as follows:--

A1 A peasant with the name of Crab (Cricket, Rat), who buys a
physician's costume and calls himself Dr. Knowall, or (A2) who would
like to satiate himself once with three days' eating, (B) discovers
the thieves who have stolen from a distinguished gentleman a ring
(treasure), by calling out upon the entrance of the servants (or at
the end of the three days), "That is the first (second, third)!" (C)
He also guesses what is in the covered dish (or closed hand) while
commiserating himself, "Poor Crab (Cricket, Rat)!" (D1) Through
a purgative he by chance helps to find a stolen horse, or (D2) he
discovers the horse that has previously been concealed by him. (E) He
gets a living among the peasants, upon whom he has made an impression
with a short or unintelligible sermon or through the crashing-down
of the pulpit, which has previously been sawed through by him.

Bolte lists over a hundred and fifty stories containing one or more
incidents of this cycle. The discovery of the ring inside a domestic
fowl (sometimes animal) is found in most of the European versions,
