Paris:: N.-P. Lerebours, 1843., 1843. 8vo. VIII, 224 pp. Half-title, numerous figs., 12 plates drawn by C.R. Goring (1792–1840) and engraved by W. Kelsall (10 of which are colored, 2 folding), numerous figures; spotted and/or foxed, with marginal damp-stains. Handsome modern quarter gilt-stamped crimson morocco, marbled boards. Ownership signature of title obscured; old rubber-stamp "Bibliotheque Populaire" (preface, p.85). Very good. First French edition of a classic of microscopic literature. Martin 163 (for the first English edition of 1832). Microscopic studies of the larvae of crocodiles, dragonflies, notonectidae or boatfly, animalcules, infusoria, gnat, green & brown polyps, satyrid butterfly, freshwater Cyclops, shrimp. Added to this are microscopic terminology, applying microscopes to precious stones, etc. One of the folding plates shows Andrew Prichard's Jewel & Doublet Microscope. Dr C.R. Goring, who made the drawings for the plates, was a medical practitioner and amateur microscopist. / "During the 1830s Goring and Pritchard published several works that presaged and helped instigate the intense publishing activity that accompanied the heightened popularity of microscopy later in the 19th century. Pritchard and Goring's illustrated books are important for their pioneering exploration of natural history and for their espousal of an ultimately fruitless innovation in microscope development: the diamond lens microscope." – Whipple Library. "Creating the original drawings of insects was not easy. Goring railed at the insects' 'incorruptible restlessness' which 'so balks and baffles the artist, that he is frequently compelled to lay down his pencil to regain his lost temper, and fresh courage to proceed'." / "Nineteenth-century England's fascination for the study of microorganisms had made optical development of the microscope an English preserve. Against this background Pritchard and Goring devoted much time to the development of lenses made of diamond and other precious stones. They sought to realize Brewster's notion of the jewel microscope as a means of counteracting two defects that had hampered the use of the existing compound microscope (i.e. a microscope containing two or more lenses). The first defect, known as chromatic aberration, resulted in a rainbow-effect caused by imperfections in the eyepiece lens and object glass. The second defect, known as 'spherical aberration', resulted from a tendency of the object glass to confuse rays of light projected through the slide by the mirror light source beyond it. This made the edges of any object under observation appear indistinct. Goring and Pritchard became convinced that these defects could be rectified through the use of a 'single microscope', comprising one lens made of diamond or some other precious stone. It was believed that the higher refractive index of precious stones would allow for a shallower curved lens, thereby reducing aberration. Unfortunately, despite Pritchard's hyperbole the innovation proved impractical as natural diamonds are too hard to work and most have flaws. Moreover, the jewel lens microscope was made obsolete by the invention of the doublet lens in 1828 by W.H. Wollaston (1766–1828) and work on the design of objective lenses for the compound microscope by Joseph Jackson Lister (1786–1869)." – Whipple Library.
