Description
Cornelius Varley first described his ‘Single Lever Microscope’ in the Transactions of the Society of Arts in 1845. Its principal feature was the long lever which manipulated the mechanical stage, making it possible to make very fine adjustments with only one hand. Varley was not a prolific manufacturer of microscopes, though his instruments were considered to be of the best quality.
