All work which is executed on a mandril partakes in some measure of the irregularities in the form of that mandril; and the perfect circularity of section which ought to exist in every part of the work, can only be ensured by an equal accuracy in the mandril and its collar.

Charles Babbage
Bordman had called it a circular problem, but he hadn't seen its true circularity.
"Sand Doom"
William Fitzgerald Jenkins
A naturalist of deserved eminence has maintained, on purely scientific grounds, that such an animal must exist,-that the laws of nature absolutely require such a being; and though the amount of force which his reasoning, possesses will be estimated differently according as we reject or accept the hypothesis of the circularity of the great plan of nature, we may as well see what he has to say for a marine primate,-be he man or ape, mermaid or mermonkey.
