— Mr. J. W. Groves, of the South London Microscopical Club, 
after cleaning glass slides for mounting microscopical objects, by 
one of the usual processes, fastens them together by their edges, 
after the manner of the well-known artist’s sketching blocks. : 
This is easily done with a pile of slips, by fixing around their 
edges a piece of ready gummed tissue-paper, ten inches long,and 
of a width suitable to the number of slides, so that, although they 
are firmly bound together, their surfaces are left uncovered. The 
block is left to dry, when each slip may be detached by running 
the thumb nail round its edges. The surface next the adjoining 
slip should be used for the preparation to be mounted on, as 1t 15, 
of course, quite clean, although the exposed one may have 
become dirty; the fragments of tissue-paper are removed after 
the mount is completed.— Quarterly Fournal of Science, London.
