MICROSCOPICAL SOCIETIES. 
Quekett Microscopical Club.—T he 380th ordinary meet- 
ing of this club was held on Friday, Oct. 19, at 20 Hanover- 
square. Mr. George Massee, F. L.S., president, inthe chair. 
Messrs. Swift exhibited their new portable microscope as 
shown at a previous meeting, with the addition of their rol- 
ler detachable mechanical stage and asub-stage condenser 
for use with the lower powers, and of such a focus as to 
give dark-ground illumination through a fairly thick water 
trough. ; 
Mr. D. J. Scourfield exhibited and described Mr. Ashe’s 
camera-lucida, a form of Beale’s well-known form, but which, 
by the introduction of a small mirror, obviates the draw- 
back of the latter instrument, which inverts but does not 
transpose the image. Moreover, the drawing can be made 
at any angle of inclination of the microscope by the use of 
an inclinable table for the paper. Mr. Lewis communica- 
ted some interesting observations made by Mr. E. G. 
Wheler, on “A Remarkable Stigmatic Organ inthe Nymph 
of Ornithodorus Megnini,’’ and also on ‘Ixodes tenuiros- 
tris.’’ Specimens and drawings were exhibited, Mr. D. 
J. Scourfield read a paper on **The Swimming Peculiari- 
arities of Daphnia and its Allies, with an account of a New 
Method of Examining Living Entomostraca, &c.”’

Laboratory Directions for Beginners in Bacteriology. 
Moore, Veranus A. Boston. Ginn & Co., 1900. The cor- 
dial reception tendered to the first edition of Dr. Moore’s 
Laboratory Directions for Beginners in Bacteriology has 
caused the author th prepare asecond edition. This edi- 
- tion is somewhat extended, and the literature thoroughly 
sifted. The course is certainly an excellent one and fora 
course of medium length has enough details to give the 
student a comprehensive idea of the subject. The work 
can be recommended most cheerfully to those pursuing a 
course in bacteriology.—L. H. PAMMEL.
