I have read your book cover to cover and then gone back and reread most of it again. I find it an excellent book, especially the first part.
The last part, regarding formulas, is rather out of date though, as are the descriptions of coating methods. Much of this could be seriously upgraded. In particular, you seem to refer a lot to Wall (and you mention him on your web site) but I find that his books are inferior to those of Baker in the same time frame. Using Wall as a starting point can be pointing the newcomer in the incorrect direction if one wants to re-create emulsion making of the early part of the century with reasonable results.
Best of luck in your second edition.
