Containing the Defcription and life of a New XJni- verfal Single Micro]cope, invented, made and fold by George Adams, at Tycho Brahe x Head, in Fleet-Street, London. T hath long been the Defire of the Curious and Inquifitive Part of Mankind, to have a Microfcope which would be Portable and Univerfal, that is to fay. One only Inftru- ment, by which all Sorts of minute Objedfs might be ob~ ferv’d. I fhall here prefent the Reader with a Defcription of One, which comprehends all the wifh’d-for Advantages, becaufe it con¬ tains a fufficient (tho9 fmall, yet all that9s neceffary) Apparatus, to perform the Effedts of all the various Sorts of Microfcopes, (and fome of them very elaborate ones too) that have been heretofore invented ; nay, I can go far¬ ther, and fay alfo of fome others that have been fince attempted. It is capable of obferving all thofe very minute Animals, which walk or crawl upon the Earth, Trees, Flowers, Sc. thofe which fly in the Air, and the Animalcula that fwim in prepared Liquors, and in thofe which have had no Preparation; it may alfo be very advantagioufly employed in examining the Circulation of the Blood, Sc. in the Infide of larger Ani¬ mals, and likewife in the Difcoveries of the minute Particles of Minerals, Plants, Sc. wherein may be perceived what amazing and ftupendious Con¬ trivances, exadt and perfedtly uniform Proportions, the great Author of Nature hath endowed thofe very minute Parts of the Creation with, which are fo extreamly fmall, as to efcape the bed Eyes deprived of this Affift- ance of human Art. This Microscope is made either of Brafs or Silver, and is compofed of/x double Convex Lens9s, of different Foci. Reprefented, as put together for Ufe in Fig. i.' When it is firft taken out of its Box, the two Legs A, B, are to be turn’d about upon the Joint C, till they make an equilateral Triangle with B the
