rare work on microscopy

First edition of an important and rare work on microscopy. Giovanni Maria della Torre (1710-1782) was an Italian scientist and corresponding member of the academies of Paris, Berlin and the Royal Society of London. He perfectioned the oculars of telescopes and succeeded, like Toricelli, in constructing powerful miscroscopes by using small glass globes. "Della Torre was a man of wide culture and of wide scientific curiosity. His studies led him into the history of philosophy, optics, and microscopy (he made several new histological identifications with an excellent compound microscope that he himself had built)". (DSB). The first 44 pages deal with the construction of different kinds of microscopes, illustrated with 2 detailed plates. The rest of the work deals with objects observed through the microscope.
