Notes: | This seaweed is of a dull green colour, having lost its original purplish red tint by exposure to air and heat probably. It is well known that all seaweeds contain chlorophyll, the green colour of which in the case of red algae is hidden by a red colourin, g matter, phycerythrine, and in the black or olive algae by phycophaeine and phycoxanthine. By the action of fresh water and heat the colouring matter which conceals the chlorophyll is destroyed, and the presence of the latter becomes evident. From the qu, anity of sand and foreign matter present, the discolouration in this case would appear to be due to the action of the heat of the sun on a sandy shore, rather than to the effects of fresh water. |
