Incomplete scan missing seven important pages: use the newer Google Books upload instead
Unfortunately this scan is missing several pages—p. 236 and pp. 244-249 inclusive—which means that a significant part of Chapter 13 of Cicero's oration is missing.
One or more of the pages of advertising at the end may be missing too, but it's hard to be sure. Several pages are also repeated out of order after p. 235. The OCR is also generally poor, but that was to be expected.
Fortunately Google Books has a newer upload which is now fully accessible. It seems to fix all the scanning problems, and to have better OCR as well. It has also been uploaded to the IA at
