    say 100 c.c. (28 fluid drachms) and adding to it 50 c.c. (14 fluid drachms) of acetone and 50 c.c. (14 fluid drachms) of amyl acetate and well shaking. The solution is colourless and, unless used too strong, or in too great a quantity, it does not impart any gloss to the objects treated. Excess of celluloid may readily be removed with acetone and a soft rag. Other varnishes that may be mentioned are {a) a dilute solution of dammar resin (generally, but incorrectly, called “ gum ” dammar) in benzol or petroleum spirit (benzine, petrol); (b) a dilute solution of mastic resin in alcohol1; and (c) a dilute solution of bleached shellac in alcohol.1 These solutions should be used in about 5 per cent, strength ; none of them is colourless, but all are slightly yellow. 1 See footnote 1, p. 20.
