PRELIMINARY ANNOUNCEMENT vii 



him an exceptional knowledge and understanding of those 

 which occur in the British Islands. 



Distribution, etc. — The local names are being treated 

 somewhat fully, and it is intended to include a full account 

 of the geographical relationships and distribution, individual 

 variation in colour, size, or form, with descriptions, measure- 

 ments, and keys for distinguishing all doubtful species. 



Illustrations. — No expense shall be spared in regard to 

 illustrations. These are being drawn by Dr Edward A. 

 Wilson, a trained naturalist as well as a gifted artist, who is 

 already well known for his beautiful pictures of Antarctic life. 

 The large numbers of explanatory or quasi-technical drawings 

 will be unique. The reproduction of the coloured and black 

 and white drawings into half-tone and line blocks is being 

 entrusted to Messrs Hislop & Day, Edinburgh. 



Typography and Paper. — The type chosen for both parts 

 of the work has been carefully selected, the smaller being 

 used in the technical and the larger in the popular section. 

 To ensure permanency, specially manufactured paper made 

 from pure rags will be employed, that for the text being 

 supplied by Messrs Alex, Cowan & Sons, Edinburgh, and that 

 for the plates by Messrs John Dickinson & Co., London. 



Form of Publication. — The work will be published in 

 about twenty-four monthly parts, at the price of 2S. 6d. each 

 net. Part I. will be ready on i8th October 1910. When 

 completed, the whole will form three volumes extra royal 

 8vo, bound in buckram, gilt top, fore and under edges uncut. 

 In issuing the Parts it is impracticable to arrange the coloured 

 and black and white plates in proper order, but a detailed list 

 of instructions for placing will be inserted in the concluding 

 Part, which will also contain Title Pages, General Introduction, 

 Contents, and Index.
