dc.description.abstractOne of the first achromatic instruments, the microscope has a heavy flat folding tripod base. The limb is attached to the pillar by a ball-and-socket joint of Ross design, and carries the body-tube, stage, condenser, and mirror. It comes with a mahogany carrying case and accessories which include a Goring engiscope. Dr. John Bunyan believed that this instrument was made by Andrew Ross and Hugh Powell, who had earlier worked for Pritchard. Signed: Andrew Pritchard, 162 Fleet Street, London.
