I finally got around to some revision:

The Wanderer: only a bit here & there needed, some new phrases or line-breaks. Saw that I had forgotten “bote” in line 113. That was the only real mistake.

The Seafarer: mostly just reconsiderations of reading & line-breaks. A distressing error in line 110. I had said “certain of his word” — “word” never appears in the actual line, not even as an emendation. “Assured among humanity” is what I replaced it with.

The Whale: Good to find these things. “lifes” mistaken for “lices” in line 69. Error removed.

The Panther: Nothing seemed to need changing. No egregious errors.
