Consists of original microscopic drawings on board which have been tipped onto blank pages. Some have ms. instructions for purposes of publication and some are in colour. There are published drawings of microscopes, insects, scientific instruments and optics which have also been tipped in. Andrew Pritchard, 1804-1882, and C.R. Goring, 1792-1840, collaborated to produce a number of works including: "The natural hisory of several new, popular, and diverting living objects for the microscope" (1829); "Microscopic illustrations ..." (1830); "The microscope cabinets of select animated objects" (1832); and "Micrographia ..." (1837). Comparisons with the published item, "Microscopic illustrations ... " show this work to contain some of the original artwork of that particular book
