Analysis of Shell Lac. 
A. 500 grains of this substance were first treated with boiling 
distilled water, as above-mentioned, and yielded of extract only

B. The 497.50 grains which remained, were then digested 
with different portions of cold alcohol, until this ceased to pro-

to 403.50 grains. 
C. As the shell lac had not been reduced into powder, but 
only into small fragments, these were become white and elastic,
