"Then change it to suit him. He's in charge of the ship and knows more about these things than I do."
"More than a man?" Firmon leered at Meredith and, when she failed to smile, added plaintively, "I did try to change it, but he still complains."
Halden took a deep breath. "Seems all right to me."
"To everybody else, too, but the tapeworm hasn't got lungs. He breathes through a million tubes scattered over his body."
It would do no good to explain that Taphetta wasn't a worm, that his evolution had taken a different course, but that he was in no sense less complex than Man. It was a paradox that some biologically higher humans hadn't developed as much as lower races and actually weren't prepared for the multitude of life-forms they'd meet in space. Firmon's reaction was quite typical.
"If he asks for cleaner air, it's because his system needs it," said Halden. "Do anything you can to give it to him."
"Can't. This is as good as I can get it. Taphetta thought you could do something about it."
"Hydroponics is your job. There's nothing I can do." Halden paused thoughtfully. "Is there something wrong with the plants?"
"In a way, I guess, and yet not really."
