Microscopic objects, animal, vegetable and mineral; with instructions for preparing and viewing them
A practical microscopy manual by Andrew Pritchard, published in London by Whittaker in 1847 for naturalists and amateurs preparing and mounting specimens. The wood-engraved figures show compound and dissecting microscopes, tripod stands, stages and mirrors, objective lenses with ray diagrams, and lettered part keys, offering designers precise instrument silhouettes, turned-brass hatching, and labelled diagram conventions.
