neck may be of about half an inch in length. Procure a sheet 
of tin, and perforate it with round holes, of which the diameter 
will be equal to the thickness of the knobs. Having greased 
the knobs well with lard, so as not only to prevent any adhe- 
sion to them, but also the adhesion of the inner sides of the 
capsules to each other after casting, pour melted glue (the 
most transparent having been selected) upon them and allow 
it to become tolerably stiff If you think the shell is too thin, 
a second coat may be poured over the first. The capsule 
having been thus cast is allowed to cool down to about the 
consistence of common india rubber, and, having run a knife 
around the neck, you twist it briskly around and pull it up- 
wards off from the knob. // will immediately collapse and 
lose the form imparted to it on the mould, hut if laid aside 
to dry, will by the time it has hardened have regained the 
desired rotundity. Place it upon your perforated tin or 
"filler" and you can thus conveniently fill it with the article 
prescribed. A small piece of moistened goldbeaters' skin 
serves to cover the opening, and is easily concealed by the 
application of a thick coat of a solution of gum arabic with a 
camel's hair pencil. This last part of the operation being in- 
tended solely for the "finish" of the article, is only necessary 
in those cases where it is proposed to keep a supply on hand 
already filled, and need not be adopted where the immediate 
use of the remedy dispenses with any necessity of so rigidly 
consulting appearances.
