2. Was the Mount Hecla at the Surrey Zoological Gardens classed by Bateman in his work upon skin diseases--if so, what kind of eruption did it come under? Where was the greatest irritation produced--in the scaffold-work of the erection, or the bosom of the gentleman who lived next to the gardens, and had a private exhibition of rockets every night, as they fell through his skylight, and burst upon the stairs? 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'Ete, the Swan in Hungerford Market, the pit of the Adelphi, Hunt's Billiard Rooms, and the Colosseum during the period of its balls. [Illustration] ANIMAL ECONOMY. 1. Mention the most liberal pawnbrokers in the neighbourhood of Guy's and Bartholomew's; and state under what head of diseases you class the spring outbreak of dissecting cases and tooth-drawing instruments in their windows. 2. Mention the cheapest tailors in the metropolis, and especially name those who charge you three pounds for dress coats ("best Saxony, any other colour than blue or black"), and write down five in the bills to send to your governor. Describe the anatomical difference between a peacoat, a spencer, and a Taglioni, and also state who gave the best "prish" for old ones. * * * * * HARVEST PROSPECTS.
