The RNA of a worm
Instructs it which way to turn,
But the RNA of his teachers
Might transmit noncurricular features
The student’s not intended to learn.
Dr. John Aeschlimann
(from “The Worm Re-Turns”)
The theme is still mortality: but instead of attempting to teach it, the hero of this doctor story (or if we must categorize, I suppose it should be a doctor-doctor-doctor story, for two authors and one protagonist), finds himself in a position to operate it.
The doctor-authors here are, respectively, from New York and California, a first-timer and an old-timer in SF. Dr. Smith is an ear, nose, and throat surgeon, whose previous publications have been in “very little magazines” and a college humor magazine. Dr. Nourse is “on extended leave of absence from practice to catch up on writing obligations,” and his list of caught-up-with-and-published writing, in and out of SF, is too long to recite here.
