Corrections to Second Printing (shipped after 1 February 1995).
All these are fixed in the the Third Printing.

Notation:
--------
P = page
L = line number
n = footnote
F = figure
E = exercise
C = code; column
^ = letter above in italics
~ = letter above in bold
= = letter above in Courier
[comments in brackets]

Substantive:
-----------
P55, F2.3:	[Part (b) of figure altered]
P55, Case 2:	[Helen Cameron pointed out the proof misses a case:]
		[Replace Case 2 with:]
		(s,t) is interior to P for all S and T.
		Suppose first that L intersects A in exactly two components.
		Then [s,t] contains a highest or lowest point,
		contradicting the assumption that A's endpoints are
		highest and lowest.
		Next suppose that L intersects A in more than two components,
		with S and T leftmost.
		Then t is an interior cusp: it must be a reflex vertex, 
		and if it were not an interior cusp 
		L would be exterior to the right of T.

P246-251:	[Amy Yee discovered that ConvexIntersect fails in several 
		degenerate cases.
		Code int.c modified; various adjustments to text.]

Nonsubstantive:
