Possibly made by Giovanni Battista Amici in his Florence period. The base of this compound microscope consists of a cylindrical box to which the illumination mirror is fixed by a swivel joint. The body-tube is supported by an arm with rackwork for focusing. A bull's eye lens is inserted on an articulated arm. Belonged to the Gabinetto degli Invertebrati of the Istituto di Studi Superiori of Florence.
