Hi Herb,

The problem is not in the auto-rotation in TeX: auto-rotation does work there. If you look at Buoyant-Oscillations.pdf, the first three pages are portrait and the fourth landscape, exactly as intended.

The problem is when printing this PDF file in TeXShop: Preview rotates automatically the landscape page before sending it to the printer, yielding the portrait output in Buoyant-Oscillations-Preview.pdf. TeXShop doesn't, however, so you get the output in Buoyant-Oscillations-TeXShop.pdf, where the landscape page is kept landscape, shrinked horizontally, cropped and inserted in portrait output.

This is in PDF files, but that's exactly when I saw first, to my great surprise, on the paper sheets out of the printer.
