The Particulars of the Plan of the Work will be found detailed below:—

1. The Engravings in every instance to be of the exact dimensions of the Drawings, which, without any exception, represent the Birds of their natural size.

2. The Plates will be Coloured, in the most careful manner, from the original Drawings.

3. The Size of the work will be Double Elephant, and printed on the finest Drawing Paper.

4. Five Plates will constitute a Number; one Plate from one of the largest Drawings, one from one of the second size, and three from the smaller Drawings.

5. There are 400 Drawings; and it is proposed that they shall comprise Three Volumes, each containing about 133 Plates, to which an Index will be given at the end of each, to be bound up with the Volume.

6. Five Numbers will come out annually.

7. The Price of each Number will be Two Guineas; payable on delivery.

TEN Numbers being now completed, will give an exact idea of the nature and style of the Work. All the other Numbers will at least equal these in interest and execution. It would be advisable for the Subscribers to procure a Portfolio, to keep the Numbers till a Volume is completed.
