The varnish is made by dissolving celluloid\in amyl acetate 
so as to produce a liquid of about the consistency of thick treacle. 
The varnish is painted over the front and back of the labels, and 
is also applied to the edges, a second coat being given after the 
labels have been allowed to dry. To get a uniform coat, it was 
found best to let the card lie flat during drying, and consequently 
only one surface was treated at a time. A third coat of varnish 
is perhaps usually necessary, but the number of applications 
In preparing the varnish two fersia of celluloid were tried. 
One of these was obtained under the name of “‘ partially digested 
celluloid,’’ or ‘‘ celluloid mass,’’ and was gelatinous in appear- 
ance. The results following the use of this substance were rand 
on the whole, satisfactory; there is therefore no need to refer 
it further 
The other material employed was waste celluloid, being, in 
one case, cuttings from sheet-celluloid, and, in the other , lengths 
of celluloid ribbon belonging to cinematograph films. To obtain 
them. e mixture is kept in a closed ia “eet stirred up 
at intervals of one or two hours. When solution is eee 
more celluloid or more solvent is added, as required, and t 
mixture stirred as be — ae is repeated until the right con-
