Diagrams of Microscopic Objects.—In looking over Mr. Beale’s 
new edition of his work, “ How to Work the Microscope,” I 
have been struck with his observations relative to drawing 
objects in pp. 26—28. There is no doubt as to the general 
correctness of his remarks, but, at the same time, it is cer- 
tain that there are many amateurs in microscopy who can 
never attain any proficiency in the eunning of the pencil. Ido 
not, however, write to bewail my own inability in this matter, 
but for another purpose. The teachings of the microscope 
have now become so popular that I, for one, am constantly 
being asked to give lectures on the subject at parish rooms, 
young men’s associations, &c.; and as it is impossible on such 
occasions to illustrate one’s observations to large audiences 
under the microscope itself, recourse must be had to diagrams, 
which I have found great difficulty in obtaining. At the 
soirée given by the Bath and Bristol microscopical societies 
in connection with the late meeting of the British Associa- 
tion, the walls of the various rooms were profusely covered 
with well-executed enlarged drawings of the principal micro- 
scopic objects in the vegetable, animal, and mineral king- 
doms, and the same is generally the case at the annual sozrées 
of the London Society. Now, it appears to me that it would 
answer the purpose of any enterprising publisher to bring out 
a well-selected series of diagrams illustrating, say, for in- 
stance, the structure of insects and plants. For these would 
find a ready sale amongst schools, families, young men’s 
associations, &c., and such a proceeding would, surely, do 
much towards popularising the microscope. ‘There may 
possibly be such a series already published, and if so I should 
be obliged to any correspondent who would inform me where 
they can be procured. 
I take this opportunity to remark that I fancy that the 
usefulness of your excellent Journal would be greatly in-
