 found in the petals of a number of species. Also reactions 

 (chemical) of pigments and their connection with tannin.

A short account is included of the physiology and 

 functions of anthocyanin. and some original suggestions 

 are made as to the conditions which bring about its 

 formation. As regards the correlation between the 

 presence of anthocyanin and the absence of chlorophyll, 

 it is suggested that the protoplasm of chlorophyll-con- 

 taining cells has an alkaline reaction, and this is unfavour- 

 able to the formation of anthocyanin.

 the pigment from every point of view. The first part is a 

 descriptive account of anthocyanin. The second part
