The bands produced by the ethereal solution obtained from the 10°/ 0 
acid fraction show exactly the same relations. Measurement gave:

Band III in concentration B is a so called double band, corres¬ 
ponding to a similar band of phylloporphyrine. It is however rather 
difficult to place the more refrangible edge of the shadow, and 
therefore we give only the position of its less refrangible edge. 
The ethereal solution obtained from the 12°/ 0 acid fraction shows 
the band I still stronger than the foregoing solution, and the bands 
must be placed according to their relative intensities in the follow¬ 
ing order: 
IV > V > I > III > II. 
A concentrated solution gave the following wave lengths: 
Band I k 677 — 652 
II I 638 — 632 
III k 592-5 — 572 
IV x 554 _ 533 
V k 518 — 485-5.
