Historical AttributesIn 1792, Harvard College authorized its treasurer to engage John Prince to make a lucernal microscope. Prince received £30 in payment for "a large lucernal microscope and box" and 12 shillings "for alteration in mounting" it in January 1796.
John Prince made notable improvements to the lucernal microscope as invented by George Adams (I), and was given credit for this work by George Adams (II) in the second edition of Essays on the Microscope (1798). Prince's improvements included "a strong joint similar to that of a telescope at about the middle of the center part of the pyramidical box, and a sort of adjusting screw at the large end." Prince also added the shadow box ino order "to secure the image formed upon the rough glass more completely from the light."
