"It has taken the form of a brown pigmentation on the hands. On the face it causes a slight itching and subsequent peeling of the affected areas."
"In other words, it is acting like sunburn?"
"Why, yes, somewhat. It is not that, however, for he has been exposed to the sun very little lately, on account of his eyes."
"I notice that he is sleeping in the new solarium which was added last winter to the executive mansion. Can you tell me with what type of glass it is equipped?"
"Yes. It is not equipped with glass at all, but with fused quartz."
"When did he start to sleep there?"
"As soon as it was completed."
"And all the time the windows have been of fused quartz?"
"No. They were glazed at first, but the glass was removed and the fused quartz substituted at my suggestion about two months ago, just before this trouble started."
"Thank you, Admiral. You have given me several things to think about. My ideas are a little too nebulous to share as yet but I think that I can give you one piece of very sound advice. The President is spending a very restless night. If you would remove him from the solarium and get him to lie down in a room which is glazed with ordinary glass, and pull down the shades so that he will be in the dark, I think that he will pass a better night."
