3. Which is the most powerful narcotic--opium, henbane, or a lecture upon
practice of physic; and will a moderate dose of antimonial wine sweat a man
as much as an examination at Apothecaries' Hall?


CHEMISTRY AND NATURAL PHILOSOPHY.

1. Does any chemical combination take place between the porter and ale in a
pot of half-and-half upon mixture? Is there a galvanic current set up
between the pewter and the beer capable of destroying the equilibrium of
living bodies.

2. Explain the philosophical meaning of the sentence--"He cut away from the
crushers as quick as a flash of lightning through a gooseberry-bush."

3. There are two kinds of electricity, positive and negative; and these
have a pugnacious tendency. _A_, a student, goes up to the College
_positive_ he shall pass; _B_, an examiner, thinks his abilities
_negative_, and flummuxes him accordingly. _A_ afterwards meets _B_ alone,
in a retired spot, where there is no policeman, and, to use his own
expression, "takes out the change" upon _B_. In this case, which receives
the greatest shock--_A_'s "grinder," at hearing his pupil was plucked, or
_B_ for doing it?

4. The more crowded an assembly is, the greater quantity of carbonic acid
is evolved by its component members. State, upon actual experience, the
_per centage_ of this gas in the atmosphere of the following places:--The
Concerts d'Eté, the Swan in Hungerford Market, the pit of the Adelphi,
Hunt's Billiard Rooms, and the Colosseum during the period of its balls.
