each number. The text is properly and scientifically classified, 

 and when the Work shall be completed the Plates can be placed 

 and be bound corresponding with the order of the Text, in 

 either threje or four Volumes. The regular issue of the Num- 

 bers will commence so soon as the number of Subscribers will 

 justify the undertaking. 



As the Work will be published for Subscribers alone, few 

 or none being printed beyond the number subscribed for, it is 

 not possible that its pecuniary value can ever be much reduced ; 

 on the other hand, the probabilities are that it will rather 

 be increased. Nor will there ever be a time when it can be 

 published at a less price than the present; for in estimating 

 the cost the mere expense of manufacturing has been taken 

 into consideration, without reference to the original cost of 

 the Copper-plates, which was nearly One hundred thousand 

 Dollars; and a very small profit has been charged on the ex- 

 pense thus estimated. 



The first Number is considered superior in many respects 

 to the same Plates in the first Edition, and it is confidently 

 hoped that subsequent Numbers will exhibit still greater 

 superiority as the Artists gain experience. A full list of Sub- 

 scribers will be published with the Work. The Numbers will 

 not be sold separately, except the first, which will be sent, 

 properly packed, as a Specimen, to any part of the country, 

 free of expense, on the receipt of 2, 8s.
