COLOURS OF FLOWERS. Professor Keegau believes that there are different stages in the development of the floral pigment. In the lower stages the natural colour is red, whatever the chromogen may be; while in the higher stages the natural colour of anthocyan is blue; or rather, at le 1st with some cliroinogeii.9, it becomes capable of forming blue compounds with alkalies and certain metallic acids. There also exist chro,mogens which, except under very ex- ceptional conditions, aro incapable of pro- ducing a blue pigment. These, in all stages, naturally develop into a red, the brilliancy of which unquestionably attests its real, origiual, and proper character.
