"I cannot read Russian," said Dr. Bird slowly, "and so was forced to depend on one of my assistants to translate the papers which Mr. Bolton found in Stokowsky's room. There is nothing in them to definitely connect him with the Russian Union of Soviet Republics, but there is little doubt in my mind that he was a Red agent and that Russia supplied the money which he spent.

When Carnes first told me of your malady, Mr. President, I happened to be checking Von Beyer's results in the alleged discovery of a new element, lunium. In the article describing his experiments, Von Beyer mentions that when he tried to observe the spectra, he encountered a mild form of opthalmia which was quite stubborn to treatment. He also mentions a peculiar mental unbalance and intense exhilaration which the rays seemed to cause both in himself and in his assistants. The analogy between his observations and your case struck me at once. * * * * * "For ages the moon has been an object of worship by various religious sects, and some of the most obscene orgies of which we have record occurred in the moonlight.

Certain feeble minded persons have been known to be adversely affected by moonlight as well as some cases of complete mental aberration. In other words, while moonlight has no practical effect on the normal human in its usual concentration, it does have an adverse effect on certain types of mentality and, despite the laughter of medical science, there seems to be something in the theory of 'moon madness.' This effect Von Beyer attributed to the emanations of lunium, which element he detected in the spectra of the moon, in the form of a wide band in the ultra-violet region. * * * * *
