during the last few years, his labors with those of his colleagues, 
Messrs. Everhart, Jeffries and Gray, have added many interesting 
species to the mycologic flora of Chester County, 
The friends who were accustomed to accompany him in ** fungus

Coloring Matter of Floiuers. — H. Hansen has separated the two 
constituents of chlorophyll by Klihne's method. He has also exam- 
ined the coloring matter of flowers. The yellow pigment is lipochrome 
and can be crystallized It shows two bands in the blue and no fluor- 
escence; that described by Pringsheim resulted from a small admix- 
ture of chlorophyll. The red coloring matter is in a state of solution 
ni the cells. The spectrum shows a broad band between D. & b. 
The shades of red are often caused by an admixture of lipochrome, 
as in Papaver^ Lilium hulbiferum, etc. The blue and violet pigments 
are also in a state of solution and show bands in the red half of the 
spectrum. Acted upon by acids, they become red. None of these 
pigments shows spectra resembling that of chlorophyll, except when 
a small quantity of that substance is present. (Jour. Royal Micros.
