Hello,

I admit that this is a repost but I truly need help on this question. I have waited for months but no one has replied. Perhaps my questions is confusing. If so, please advise!

I am a beginning logic teacher. I noticed on page 10 of Cothran's *Traditional Logic book II* that he says there are 19 valid syllogisms. But, if the conclusion of the syllogism is included as part of the mood then there are 5 more syllogisms that are valid, namely, AEO-2, AII-1, EAO-1, EAO-2, and AEO-4 for a total of 24. These are legitimately valid syllogisms but don't seem to be accounted for.

What am I missing?

Thanks for helping.
