Two essays on the nature and wonderful properties of Island Crystal
Essay I. Containing, all that has been hitherto delivered in regard to its form, dimensions, and double refraction of light; with the addition of several new experiments with polished parallelopipeds and prisms made of this substance, which discover a various, multiple, and colorific refraction; and exhibit a variety of images of one and the same object. To which is subjoined, a computation of the magnifying power of reflecting telescopes; and a table thereof, from 6 inches to 12 feet in length. The whole illustrated with copper plate figures. By Benjamin Martin -
An essay on the genuine construction of a standard microscope and telescope
With the application of a prismatic or catadioptric eye-piece to refracting and reflecting telescopes, by which their lengths are much contracted, their fields of view encreased, and their uses greatly facilitated; particularly in the reflector of Cassegrain's form for celestial observations. By B. Martin -
Uraniscopium magnum, or The nature, construction, and use of the grand uraniscope
Being a new construction of an equatorial telescope, which, by clock-work, and a planetary pendulum, becomes an automaton, and renders all the heavenly bodies stationary to the view. By B. Martin -

Some account of the discovery, made by the late Mr. John Dollond, F. R. S. which led to the grand improvement of refracting telescopes, in Order to Correct some Misrepresentations, in Foreign Publications, of that Discovery: with an attempt to account for the mistake in an experiment made by Sir Isaac Newton; on which Experiment, the Improvement of the Refracting Telescope Entirely Depended.

Description of the two feet and half achromatic telescope
Made by P. and J. Dollond, in St. Paul's Church-Yard, London. The object-glass of this Telescope is composed of two glasses, one convex of crown glass, and the other concave of white slint glass; the diameter of the aperture is two inches. The plate represents the Telescope on its stand: AA is the wooden tube 2 1/2 feet long. The tube BB, that contains four eye-glasses, to be used for land-objects; and also the tube C, that contains two eye-glasses for astronomical purposes, are to be serewed into the end of the brass tube D. By turning the button a, this tube moves out of the wooden tube to adjust the eye-glasses to the proper distance from the object-glass, so as to render the object distinct. The magnifying power with the eye-glasses for land objects is near 50 times, and with those for astronomical uses it is 80 times. The stained glass b is applied to the eye-tube C to guard the eye in observing the spots on the sun. This glass must be taken off when the eye-tube is used for any other purposes. The vertical and horizontal motions are given to the Telescope by means of the joints at c and d. Description de la lunette Achromatique de Deux Pieds et Demi, Fait pair P. et J.
