A way how safely and speedily to make an approach to a castle or town-wall, and over the very ditch, at noon-day. NOTE. A wheel carriage, of sufficient strength to support an heavy iron tower, must first be provided. It may be constructed of thick wrought iron, with door, &c., of the same material, and hung round with sand-bags, through the interstices of which may project from six to eight small guns to protect it from musquetry. The most eligible method of moving the tower appears to be by fixing small handles to the axles of the wheels, which may be turned at pleasure by those within the walls. To prevent any attempt of the enemy who may sally forth to drag the machine within the walls of the town, &c., it will be adviseable to arm the wheels with long steel studs, which, when the handles are fastened within, will render it immoveable. This tower, though but of little use in modern warfare, appears well adapted for reconnoitring the walls of a fortified town, and, if fixed upon a hollow iron vessel, will possess the further advantage of crossing rivers and moats. Nearly similar machines are described by Vitruvius, and other authors who treat on military engineering. No. XXXII. How to compose an universal character, methodical and easy to be written, yet intelligible in any language; so that if an Englishman write it in English, a Frenchman, Italian, Spaniard, Irish or Welchman, being scholars, yea, Grecian or Hebritian, shall as perfectly understand it in their own tongue as if they were English, distinguishing the verbs from the nouns, the numbers, tenses, and cases, as properly expressed in their own language as it was written in English. NOTE. The great difficulty which the various contrivers of a universal character or philosophical language have hitherto had to encounter, from the Marquis of Worcester and Bishop Wilkins down to M. Lodowick, appears to have arisen rather from the difficulty attendant on engaging the several nations to use it, than in inventing the most convenient character. The _real character_ of Bishop Wilkins, which there is every reason to suppose strongly resembled that of his contemporary the Marquis, was repeatedly recommended by Dr. Hook, who, to engage the world in the study of it, published some curious inventions of his own, tending to its illustration. But the most accurate notice on the history of _pasigraphy_ yet published appeared in the _Spect. du Nord_ for May, 1798. The anonymous author of this interesting memoir commences by a brief inquiry into the nature and utility of the universal character, and then proceeds with this very just eulogium on our immortal countryman Bacon.
