*** Still to do ***

List faulty figures and correct them
  also check the figure numbering
mostly OK

Check all cross-refs [part of proofreading]
mostly OK

Intro, Fig 0. Coordinate model and car park

Fig 3.14c, p. 67. The circular blob at the middle (surrounded by angles
a,b,c) comes out as a black cross on my copy. ? Resolution problem --
same as the one you already solved before.

1.16.4 the dotted circle in Fig 1.16g doesn't really work. The triangle
should be much more scalene for that to make sense.

end of App A, p. 225 [244]
Polar bear -- He could be 50\% bigger and a bit higher up on the page

1.16.3 the converse of (1) is obviously false. I have cut it out.
(grep for %%%%% in eucl.tex)
We could leave it at that.
However, we could have a reference to an Ex in Chapter!affine to state
and prove it correctly. The statement is quite possibly a particular
case of Desargues, with "same ratio" interpreted as "in perspectivity"
and parallel interpreted as concurrent at a point at infinity.

Ex. 3.19 and 3.20 do the calc better?
They are at least approx correct, and we could leave it at that

5.9 Figure 5.9, the two triangles are supposed to be in grayscale,
but it doesn't necessarily come out in printing.
We could leave it at that.

5.10, ref to Hilbert and Cohn-Vossen for proof of Pappus by
lifting to lines on quadric in PP^3. Or work out as Ex.

Leave it at that.
