mechanics of Microscope construction have not yet reached the limit of 
their capabilities. The latest acquisition of medical science, the bacteria, 
has put the greatest demands on the Microscope, and reveals to this 
instrument the deepest secrets of nature. Let it be the aim of science 
to gather in a still richer harvest by the aid of the Microscope ! 
The Microscope banished. — The following appears in the Daily 
News of the 9th April : — “ An interesting paper by Mr. Bothamley in 
The Photographic Quarterly reminds us of the important part now played 
in education by the optical lantern which in the memory of so many 
among us was a mere toy for the entertainment of juvenile parties. 
The initiation and growth of the system is mainly due to Professor 
Miall, of the Yorkshire College, Leeds, in which important institution 
almost every department has its lantern, and such widely different 
subjects as biology and engineering, ancient history and textile industries 
are alike illustrated by this convenient means. In the biology lectures 
the lantern is said to have well nigh banished the Microscope , thereby 
effecting a great saving both in cost and time (!) The production of 
lantern slides is found to be most easily and rapidly done by photography. 
Original objects, drawings, large photographs, illustrations in text- 
books, can all be reproduced in the same way. At the Yorkshire 
College the number of slides required by the various departments is 
stated to be so large that the whole time of a special photographic 
assistant is occupied with their production, although the work is much 
facilitated by the ingenious copying camera devised by Professors Barr 
and Stroud. But perhaps the most remarkable fact in connection with 
this subject is Professor Miall’s discovery of how the lantern may be 
used in illustrating lectures in a room illuminated by daylight.” 
Miss V. A. Latham, F.R.M.S.* — This lady has recently been 
elected to the chair of Demonstrator in Pathology in the University of 
Michigan. Professor Latham is the first lady who has held any office 
in the Medical Department of the University, and has our congratula- 
tions and best wishes for her success.
