THE PATENT SHOE. 263 
The solution in which they are finally to be kept should be a 
very little below saturation. 
Evaporation is much less liable to happen than if spirit is 
employed ; yet, should it occur from any accident, crystallization 
would result, unless this precaution were adopted. 
It would be well to add about half an ounce of very clean 
water to a quart of the saturated solution. When the specimens 
are put into a solution of proper strength, and perfectly transpa- 
rent, and the parts properly separated to exhibit the different 
objects it is designed to show, the next point of importance is to 
close the bottle with accuracy and neatness. 
For the reason already stated, glass, with a medium of resin 
is chosen. Make the rim of the bottle perfectly dry, and spread 
on it some resin with a common spatula. The glass (previously 
fitted) is then applied ; and, by holding a warm spatula pretty 
close to it, the resin softens, and the top is fixed with the utmost 
accuracy. It is best to conduct the process in a moderately warm 
room, and the glass should be rather less than the circumference 
of the ring, or on lifting the bottle by the top, as is very generally 
done, the glass might be raised. 
With small bottles it is sufficient to make the resin smooth, 
and then varnish it ; but, on bottles of a larger size, additional 
security is obtained by attaching a slip of bladder round the 
edge by means of glue. 
I shall be most happy to shew any person inclined to inspect 
them the preparations which I have by me.
