In these days of cramming for examinations it is pleasant to 
find a course of teaching carried on purely for the sake of im- 
parting knowledge of any kind. The recently issued numbers 
of the “Journal of the Quekett Microscopical Club” contain, 
among the usual matter, reports of demonstrations given during 
the Session on subjects of importance to microscopists. This is- 
not the first time that this Society has shown its anxiety to pro- 
vide for the instruction of its younger members. Soon after its 
commencement, in 1865, arrangements were made for a course 
of ledtures on the use of the microscope, and, thanks to the 
leCturer and his zealous demonstrators, the pupils acquired con- 
siderable knowledge of the manner of conducting histological 
investigations : so great was the success of this first attempt 
that in two succeeding years the lectures were repeated, and 
many of the pupils in the first course were able to render valu- 
able service as assistants in the second and third. During the 
early part of the present Session the following demonstrations 
have been given by members who have made a special study of 
their respective subjects : — “ Staining Tissues,” one of the most 
recent and valuable aids to research. “ Photo-micrography.” 
“ Shore Collecting,” a subject upon which very little has been 
written, and where the experience of a collector accustomed to 
work on the sea-coast must prove of the greatest value to in- 
tending inquirers. “ Preparing parts of InseCts,” a subject full 
of difficulties to the unassisted beginner. “ Microscopic Vision,” 
n which the much-negleCted discoveries of Professor Abbe were 
simply and clearly explained. “ Mosses,” by a botanist who has
