⁂ 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 perfected the oculars of telescopes and succeeded, like Toricelli, in constructing powerful microscopes by using small glass globes.
