Some small typos fixed in 7.3 plus an incorrect reference in the original fixed. 

These are all small issues that I noticed as I worked on 7.3. The correction that you may not agree with is that one at the end: W&W incorrectly cited Lagrange's  Theorem. The reference is actually  on p 25 of the third volume of his "Oeuvres", not the second.
