The King George III Collection

 

DOCTOR DEMAINBRAY endeavours to render this Course entertaining and improving, being particularly calculated for such GENTLEMEN and LADIES, as would chuse to be acquainted with the more rational and sublimer Parts of Knowledge in the most expedious and familiar Manner; and he attempts giving the most obvious Demonstrations, illustrated with Variety of curious Instruments and working Models, not only of such Engines in Mechanicks, Hydraulicks, &c. as are known in Great-Britain, but of such as are in Use abroad, and not in Practice in these Kingdoms; which the Doctor has had uncommon Opportunities of collecting, and which he caused carefully to be modelled on the Spot, according to regular Scales, having ever had most at Heart, the becoming an useful Member of Society in this his native Country; some slight idea may be framed of his large Collection, by the Contents of the following Abstract of the Subjects of each Lecture, in which, for Brevity's sake, it is impossible to descend to the Particulars of the Apparatus, which tho' so extensive, is not only framed to fix the Eye, but instruct the Mind, with what Truth Geometry can afford, without its apparent Difficulties, when these Lectures are regularly pursued, and their Chain, as depending the one on the other, followed without Interruption, the Honours these Lectures have received by the Approbations of the different Royal Societies and Royal Academies, before which they have been read, may claim some Credit, since their Success has made the Doctor be received a Member of each to which he has been called; tho' even in some Cases contrary to the usual foreigh academical Regulations.
