CHL-770 FROM GREEN BACTERIA 431 



ACKNOWLEDGMENTS 



The magnesium determination was done under the direction of Mr. S. J. 

 Tassinari in the Department of Nuclear Engineering. The nitrogen determina- 

 tion was carried out by Miss Frieda Englberger under the direction of Dr. M. 

 E. Koshland. Research was carried out at Brookhaven National Laboratory 

 under the auspices of the U. S. Atomic Energy Commission.
