  Dr. F. H. Willard,

  National Research Council,

  2101 Constitution Avenue,

  Washington, D.C.

  Dear Dr. Willard:

  I received the sums of $900 and $1000 as Grants-in-Aid in 1930-1 and 1931-2. These were used to pay half the salary of an assistant, Dr. J.H. Sturdivant, who devoted his time mainly to designing a special x-ray ionization spectrometer for use in the determination of electron distribution functions in crystals. The spectrometer has now been completed, and much valuable information is being obtained with it. The results have as yet not been published, but will be published soon. In addition we have discovered a new and straight-forward method of crystal-structure investigation, using the phenomenon of anomalous dispersion, and requiring the spectrometer. This work also will be describe soon. I shall send reprints as they become available.

  The program of work we have been carrying out has been a difficult one, which was originally made possible by the Grants-in-Aid, for which I am very grateful.

  Sincerely yours,

  Linus Pauling

• Letter from LP to Dr. W. E. Bleick, Institute for Advanced Study, Princeton, NJ, RE: LP would like to know what Bleick has based his opinion regarding the NH4-F distances in NH4F on x-ray data. [Filed under LP Books, 1939b.4]

  Dr. W. E. Bleick,

  Institute for Advanced Study,

  Fine Hall, Princeton, N.J.

  Dear Dr. Bleick:

  I am interested to learn that you base your opinion regarding the NH₄-F distances in NH₄F on x-ray data. There is no x-ray information showing one of the four distances to be not effectively equal to the other three. The values 2.63 and 2.63 A you mention are calculated for the parameter value 0.375, whereas 0.382 would make all four equal. This parameter has been only roughly determined experimentally. Zachariasen in the summary of his paper wrote "Parameter u etwa 3/8". My x-ray experience would lead me to interpret this as u 0.375 0.030. Only the most accurate papameter determinations are written 0.005. I think that you will find on carrying out the Madelung constant calculations that your explanation requires a bigger deviation of the parameter than is allowed by Zachariasen's work.

  Very truly yours,

• Letter from LP to Orin F. Stafford, University of Oregon, to LP RE: LP is glad to speak at the Sigma Xi- Phi Beta Kappa Initiation and Banquet. He will be in Corvallis on Friday, Eugene on Saturday, and Portland on Sunday. Suggests that his original title "Electrons as Waves" can be replaced by "Waves and Particles." States his talk will be suitable for a general audience but that he would still like to speak with Stafford about its character.
