 SPiLL V, celluloïd manuf'g 00, 707 �Spill V. The Celluloïd Manufactubing Gompant. �(CircuU Court, S. D. New York.

The claim is in these words: "The preparation and use of solvents of xyloidine, such as have been before described, so as to render xyloidine more easy of conversion into compounds coutaining xyloidine, which are suitable for applications in the arts and for indus- trial purposes." The defendant has infringed this claim by using camphor, in conjunction with alcohol, as a solvent of xyloidine. The defendant mixes ground and dried xyloidine with pulverized dry camphor, and then immerses the mixture in alcohol until the xyloidine is dissolved. It is dissolved by the joint action of the camphor and the alcohol. Neither alone is a solvent of xyloidine. It is immaterial, so far as the invention and the claim of the patent are concerued, whether the camphor and the alcohol are mixed so as to dis- ����
