266 DR. C. A. MAC MUNN ON ENTEROCHLOROPHYLL, AND ALLIED PIGMENTS. 
Fig. 7. Crystals (which, according to Hansen, are those of the lipochrome # ) from a 
petroleum-ether extract of saponified enterochlorophyll of Urcister rvbens 
(the outline of lower figure is that of a droplet of liquid). 
Fig. 8. Crystals obtained from an alcohol-ether extract of the same soap (belonging, 
according to Hansen, to “ chlorophyll green ”). 
Fig. 9. The same with crossed Nicol’s, but without selenite, showing the peculiar 
black cross. 
# It Las yet to be proved whether these crystals may be merely coloured by tbe lipochrome; possibly (?) 
they belong to one of the fatty acids, cf. e.g., crystals of the so-called margarin.
