- Letter from LP to J.D. Bernal RE: Asks Bernal to recheck his earlier (1928) work on the structure of eta-bronze and, if possible,
to send crystal samples used in his earlier work. LP and Dr. David Shoemaker have discovered a different length for the repetition
of the crystal structure for eta-bronze (based on twenty-year old samples from Bernal) than that given by Bernal’s original
investigation. LP wonders if there was a mistake in Bernal’s original investigation or whether eta-bronze occurs in two forms.
