Dear Wyckoff:
I am returning separately the photographs of aluminum metaphosphate which you sent to me two years ago. Our suggested structure agreed well with the data except for one reflection, 800, which did not appear on your photograph although calculated to be strong. I have now grown crystals of the substance and photographed them with copper radiation and find that this reflection does appear with medium intensity - probably the range of oscillation on your photograph was such as to not bring the plane into position to reflect. Dr. Sherman and I have submitted our paper to the Zeitschrift fur Kristallographie for publication.
With best regards, I am
Sincerely yours,
Linus Pauling
