"No!" Ruut almost shouted. "It's dangerous." He rapidly gave an oral and somewhat horrified account of his earlier communication with Tensor.
"All right," the physician grudgingly admitted. "I'll try to do it superficially. But it's difficult. It's awfully hard to know what's going on in his body from just looking at it and listening to him talk."
He turned to Tensor. "How long have you been having these—er, spurious moods?"
"About six months."
"Are you having any other troubles?"
"No sir. It's just the simple things, like the weather, that seem to be affected."
"I see. Melancholia." Curl frowned thoughtfully. "These moods come unwillingly, is that it? And they don't go away entirely when you shift your endocrine balance?"
"I'm not so sure about that endocrine shift, sir," Tensor stated emotionlessly.
"You mean—" Curl stopped incredulously. He shook his head as he comprehended. "Great Iso Oxys!"
"What is it?" Ruut asked in a hushed voice.
