Dear Mr. Buckley,
I have before me in green and white the Selected U.S. Government Publications pamphlet Volume 1, Number 6-1972. It states that for only 65¢ I may order a pamphlet titled “Effect of Ceramic Spectral Emissivity Variation on the Computed Luminous Emissivity of the NBS Standard of Light.” Since I find it hard to trust the Federal Government, I am asking you—are they putting me on?
