THE Author has not been able to examine the work since it came from the press, but from the great pains he has taken to correct the proofs, he feels confident, that but few errors can have passed unnoticed; only one has as yet come to his knowledge, which is on page 63 question sixth, (and this error is in about 200 copies only) for 200 read 20.

To prevent speculators from hurting the sale by enhancing the price, the author thought it best to publish the wholesale and retail prices in the title page; the price of scale board and full binding having been omitted in that page, it becomes necessary to mention the price of the different bindings again in this place.

In scale board binding with blue paper covers, 55 cts. single ; $5.40 cts. per dozen; $35 dollars per hundred.
