well done. The informntioii here is of renl value. The siibject,s considered, among others, are : the use of cellu!ose esters 8s bnses for films; solvent,s and diluents; the nature of cellulose ester solutions; viscosity; plast,icity; resist,nnce to light; covering power; miscibility and tlie formulntion of lncquers for specific purposes.
The bliird nnd last section deals with the plant and innciiiiiery necessnry for the manufacture of Incquers, such 11s misers, clnrifiers, colour mille, snfety devices, with methods for determining viscosity, gloss, flash point, elnsticity, hnrdncss, tmnspnrency, and ot,hcr properties.
