Amongst the other articles now well known are—a Swimmingbelt—a _Diving Ark_, identical with the Diving Bell since re-invented—a _Humbling Mirror_, the object of which is to reflect a human being in a squat form—and the _Automatical Virginals_, which seem neither more nor less than a barrel-organ with clock-work. ‘It plays only foreign springs, but I am told it might be made to play Scots tunes.’ There was also the now little-heard-of toy called _Kircher’s Disfigured Pictures_. A sheet of strangely confused colouring being laid down on a table, a cylinder of polished metal is set down in the midst of it, and in this you then see reflected from the sheet a correct picture of some beautiful object. ‘There happened to be an English gentleman there, who told it was one of the greatest curiosities now in Oxford College.’ It was a toy, be it remarked, in some vogue at this time among the Jacobites, as it enabled them to keep portraits of the exiled royal family, without apprehension of their being detected by the Lord Advocate. Not long after, we find Young coming forward with an invention of a much more remarkable kind than either the detective-lock or the manifold writing-engine. He stated (July 23, 1696) that he had invented, and with great expense perfected, ‘ane engine for weaving, never before practised in any nation, whereby several sorts of cloths may be manufactured without manual operation or weaving-looms.’ He had ‘actually made cloth thereby, before many of the ingenious of this kingdom.’ He believed that this engine might, with due encouragement, prove highly useful, ‘especially for the trade to Africa [Sidenote: 1694.] and the Indies,’ and therefore petitioned the Privy Council for the privileges of a manufactory and for a patent right. The Lords complied with his request, giving him exclusive use of his machine for thirteen years.
