‘MR. JOBBA produced a forcing-machine on a novel plan, for bringing joint-stock railway shares prematurely to a premium. The instrument was in the form of an elegant gilt weather-glass, of most dazzling appearance, and was worked behind, by strings, after the manner of a pantomime trick, the strings being always pulled by the directors of the company to which the machine belonged. The quicksilver was so ingeniously placed, that when the acting directors held shares in their pockets, figures denoting very small expenses and very large returns appeared upon the glass; but the moment the directors parted with these pieces of paper, the estimate of needful expenditure suddenly increased itself to an immense extent, while the statements of certain profits became reduced in the same proportion. Mr. Jobba stated that the machine had been in constant requisition for some months past, and he had never once known it to fail. ‘A Member expressed his opinion that it was extremely neat and pretty. He wished to know whether it was not liable to accidental derangement? Mr. Jobba said that the whole machine was undoubtedly liable to be blown up, but that was the only objection to it. ‘PROFESSOR NOGO arrived from the anatomical section to exhibit a model of a safety fire-escape, which could be fixed at any time, in less than half an hour, and by means of which, the youngest or most infirm persons (successfully resisting the progress of the flames until it was quite ready) could be preserved if they merely balanced themselves for a few minutes on the sill of their bedroom window, and got into the escape without falling into the street. The Professor stated that the number of boys who had been rescued in the daytime by this machine from houses which were not on fire, was almost incredible. Not a conflagration had occurred in the whole of London for many months past to which the escape had not been carried on the very next day, and put in action before a concourse of persons. ‘THE PRESIDENT inquired whether there was not some difficulty in ascertaining which was the top of the machine, and which the bottom, in cases of pressing emergency. ‘PROFESSOR NOGO explained that of course it could not be expected to act quite as well when there was a fire, as when there was not a fire; but in the former case he thought it would be of equal service whether the top were up or down.’ * * * * * With the last section our correspondent concludes his most able and faithful Report, which will never cease to reflect credit upon him for his scientific attainments, and upon us for our enterprising spirit. It is needless to take a review of the subjects which have been discussed; of the mode in which they have been examined; of the great truths which they have elicited. They are now before the world, and we leave them to read, to consider, and to profit.
