The outside of this member gradually assumed to its inside a gigantic magnitude; it had always annoyed me at the hatter's from a merely animal bigness, with no commensurate contents to show for it, and now I detested it more than ever.

Plotinus was less ashamed of his whole body than I of this inconsiderate and stupid appendage.

To be sure, I might swim for a certain distance under water.
