the low figures of Willstatter and Page may have been due to the rapid 

 decomposition of chlorophyll in algae which were not freshly gathered. 

 Lubimenko (1925) found that the concentration of chlorophyll is 

 especially low in red marine algae from great depths (e. g., 40 meters), 

 while the concentration of the red pigment (phycoerythrin) increases 

 with depth (c/. Table 15.VII, page 421). Seybold and Egle found a
