Excerpt from Transactions of the Microscopical Society of London, Vol. 3 IT has been before noticed that less attention has been bestowed upon the investigation of objects that lie near at hand, within an inch or two, we will suppose, of the eye, than upon objects which are placed at a considerable distance from it, that, for example, of as many furlongs. I have also endea voured to show that small circular perforations made in a card, and rendered semi-transparent, constituted in themselves objects well adapted to illustrate the magnifying power of short spaces, by presenting a rapid and palpable enlargement of the visual angle to the eye and, lastly, a series of phenomena has been described, which resulted from viewing small figures held close to the eye in front of such apertures, and rendered visible by the light admitted through them. The whole subject arranges itself therefore under two dis tinct divisions, which comprise An examination of the images formed by viewing objects held in front of small aper tures and 2. An examination of those images which result from placing the objects behind the apertures. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
