Hello,

2 fonts are visible on this scan, 1 serif, and 1 sans-serif.

I first thought about Charter for the serif font, the the "fi" ligature doesn't match.

Here is another picture of the book, assuming it's the same font: http://i.imgur.com/EannN3B.jpg

Thank you.

Too fuzzy for me.

I'll try to upload a better picture quickly.
