* From some misunderstanding, the types have been reversed from their ordinary use in such cases. This was discovered after the index was set up,
and it was too late to make the change. The author thinks it is proper to state that, owing to his distance from the press, and the rapidity with which
the printing was done, he was not able to revise the proofs.
