precipitated in brown flocks, After washing and drying it was 
extracted with alcohol and the extract evaporated. The coloring 
matter thus obtained, which the authors call Ruficoccin, is difi- 
cultly soluble in cold water, readily so in alcohol, giving a yellow 
fluorescent solution, partially volatile, giving a red vapor com 
densing to yellow-red needles, and colors mordanted cloth like 
cochineal though less brilliantly. Its formula is C,,H,,0,

believe it to be a derivative of dimethylanthracene and assign to 
it the formula: ch).

This view is strengthened by the fact that when the va or of

gives oxyneurine by oxidation and subsequent removal of hydro- 
chloric acid, thus:—
