opposite
wall, the entire chamber will remain in perfect
darkness, and all the objects in it invisible, except in as far
as small motes floating in the air mark the course of the
sunbeam by reflecting portions of its light. Upon project-
ing a fluid or small dust across the course of the beam its
presence also becomes perceptible. The instrument exhi-
bited consisted of a tube With an opening at one end to be
looked into, the other end closed, the inside well blackened,
and a wide opening across the tube to admit strong light to
pass only across. On looking in, all is perfectly dark, but
a small trigger raises at pleasure a small ivory ball into the
course of the rays, and its presence instantly reveals the
existence of the crossing beam by reflecting a portion of its
light.
AGREEABLE INTERRUPTION TO A DRAMATIC
SuccEss.—Thesuccess of lrnnani was secured by the
monologue of Charles V. in the fourth act ; that tremendous
monologue was interrupted at almost every verse by bravos,
and ended in interminable rounds of applause. These
shouts were still going on, when some one came to tell the
author that he was wanted. He went out and saw a little
man with a round belly and staring eyes. "My name's
;flame," said the little man. " I'm the partner of M.
Baudoin, the publisher : but we can't talk here: " will you
spare me a minute outside the house ?" When they were
in the street, "Now, then, he said. "M. Baudoin and I
were at tle performance, and we should like to publish
' Hernani'—will you sell it ?" " What do you offer ?"
,r Six thousand francs" (£240). " w will talk about it
when the i;erformance is over." " I beg your pardon,"
said the publisher, " but I make a great point of settling
the matter at once.. "Why ? You don't know what you
are buying. The success may be less complete." " Ah,
that's true, but it may be much greater. At the second act
I thought of offering 2,000 francs ; at the third act I got up
to 4,000 ; I now, at the fourth act, offer 6,000 ; and after
the fifth lam afraid I should have to 10,000." "Well,"
said M. Victor $u go, u laughing, "since you have so much
fear about the I'
lay, you shall have it. Come to-morrow
morning, and we Will settle the waiter.'' "If it's the same
thing to you, I
should prefer settling it at once. I have
get the 6,000 francs in my pocket." " I've no objection, but
how can it be managed ? we are in the street." " Here's a
tobacco shop." .jho publisher entered with the author,
bought a sheet of stamped paper, and asked for a pen and
ink. The treaty was written and signed on the counter,
and the author received the money, which was by no means
unacceptable, as he had not more than 50 francs in his pos-
session, He went back into the theatre as fast as possible,
and saw, by the universal attention paid, that the success
