Dear Lawrence:

I am enclosing a copy of my letter to Lamb. Gordy's photographs on the two methyl compounds extend to about s₀ = 24 and show about twice as many rings as yours. They agree with yours as far as you go except perhaps for a small difference in scale. Just to be sure that nothing has gone wrong with our wavelength calibration, I am having the boys repeat that now. There is of course the chance that our calibration has got off by about 1%, which would explain part of the difference in results. I shall let you know when the calibration has been completed

Your results on thiocyanic acid are very interesting.

I am sending a photograph separately; I am sorry to have forgotten about it. I am feeling very lively now, and I am giving four lectures a week, two in my graduate course on the nature of the chemical bond and two to the freshmen. Did I tell you that I had been teaching the freshmen since a year ago and that this year we are using a textbook which I have written?

With best regards, I am

Sincerely Yours
