ContributionIntroduced the "bar-limb" construction of microscopes.
ReferenceFord
NotesThe microscope tube was mounted on a metal bar projecting at right angles from the vertical support. This design was introduced almost simultaneously by Powell and Leland, and was widely used by English makers for the next half century. Ford notes its similarity to the "aquatic" simple microscopes of the 1920's, and its influence on later compound instruments. The bar-limb is clearly evident in Powell and Leland's celebrated "No. 1" microscope of the 1870s. See 1839.
