of calcium chloride, made by dissolving white marble 
in hydrochloric acid until all effervescence ceases, and 
a saturated solution is obtained. 
But by far the most preferable method—and it is 
the one I always pursue now—was described by 
M. E. Dubreuil in an article entitled “ Procédé pour 
la préparation des Limaciens,’ which appeared in 
‘“‘ La Journal de Conchologie,” for 1864, pp. 243-245. 
The animal is first killed and washed in pure water, 
to which, after the lapse of six or eight hours, some 
salt is added. <A slit is then made along the lefé side, 
and the animal skinned. Thus, by means of two more 
longitudinal slits, three preparations can be made—: 
one to show the back, one the foot, and the third the 
right side with the pulmonary orifice. These are 
glued on cardboard, varnished with white shellac 
varnish, to which a little corrosive sublimate has been 
added, and duly labelled. 
In conclusion, do not go to the unnecessary expense 
of buying a special cabinet for your shells. Lay them 
on cotton wool, in cardboard trays, having one tray to 
each species or variety. These trays may then be 
stored away in boxes for future reference. And 
never forget to label your specimens, writing on each 
label the scientific name—and, when requisite, the 
varietal name in addition—of the species, locality, and 
date of capture.
