On a Method of Dry Mounting. By James Smith, 
Esq., E.L.S. 
(Read December 13th, 1865.) 
(Abstract.) 
The object of this paper was to show how to prepare cells 
for mounting dry objects, so as to be ready for use at any 
time, and capable of an immediate application to glass slides. 
The author proposes to take a piece of card-board of six 
or more inches square, according to the number of cells 
required, and rule a series of perpendicular and parallel lines 
-f-th of an inch apart, so as to divide it into squares. The 
centre of each square is then to be perforated with a \ inch 
punch, and both surfaces of the card-board covered with a 
cement formed of shellac or marine glue dissolved in naphtha ; 
one to three coatings of this cement being usually sufficient, 
care being taken that one is perfectly dry before the next is 
applied. The cells being thus prepared, they can be cut off, 
and by the application of heat and slight pressure are easily 
attached to a glass slide. The object being placed in the 
cell, a thin glass cover may be heated and so fixed, or this 
and the edges of the cell itself covered with a coating of 
cement. The author concluded by stating that leather or 
thin wood might be readily converted into cells in the manner 
described, but that for all ordinary purposes, those prepared 
of card-board would be found quite efficient.
