On P. 74, I think the "Disjunctive Syllogisms" chart has a typo for the first of Ponendo Tollens:

Either P or Q
P
Therefore, not P

should be:

Either P or Q
P
Therefore, not Q

Page 70 has it right.

Todd,

You are right. We have made the correction on the newest printing. (It started shipping this month.)

Thanks for pointing it out.
