A further and more complete examination is needed, but this must be 

 deferred until plenty of material is available. Three things appear to 

 be desirable. The first is to make a macrochemical and spectroscopic 

 examination of the Poppy pigments. The second, to determine whether 

 the raw material of the pigment (chroruogen of Reinke) exists in the 

 albinos, and whether the colour may be, for instance, brought out by 

 oxidation. The third is to cross the albino with the type and determine 

 whether all the progeny is typical to the second generation. For the- 

 pigment of the centre of the flower appears to be a character clearly 

 differentiating the typical from the albino race, and Mendel's Law may 

 well be tested by means of it.
