 Early in August, FitzRoy discussed this position with Beaufort, who had a scientific network of friends at the University of Cambridge.At Beaufort's request, mathematics lecturer George Peacock wrote from London to Professor John Stevens Henslow about this "rare opportunity for a naturalist", saying that an "offer has been made to me to recommend a proper person to go out as a naturalist with this expedition", and suggesting the Reverend Leonard Jenyns.Though Jenyns nearly accepted, and even packed his clothes, he had concerns about his obligations as vicar of Swaffham Bulbeck and his health, so declined.
