This day is published, in royal Octavo, price 3s. 6d. the First Number of 
an entirely new Periodical Work, in elucidation of that very beautiful 
and interesting department of Science, 
HE NATURAL HISTORY of the NESTS and EGGS of BRITISH 
BIRDS; the Descriptions, which are calculated for the Naturalist 
as well as general Observer, are intended to comprehend every useful 
trait of Information respecting the Nidification, Eggs, and Incubation of 
the numerous Species of the Feathered Tribes that inhabit the British 
Isles ; and are throughout accompanied by a Series of elegantly-coloured 
Plates, comprehending Figures of the Eggs of every Species, with their 
most singular Varieties, so far as they can be correctly ascertained. 
The whole exclusively executed from Nature, and disposed according 
to their respective Genera, 
By E. DONOVAN, Esq. F.L.S. M.W.S. &c. 
Member of the Zoological Society of London; Author of the Natural 
History of British Birds, in Ten Volumes, and other approved Works 
in various branches of Zoology. 
London: Printed for the Author, and sold by all Booksellers. 
The manifest importance of this Work to every one interested in the 
study of Natural History must be obvious ; the undertaking is one of as 
much originality as beauty, and will, it is presumed, be considered an in- 
dispensable companicn to almost every work on the subject of European 
Ornithology, and to that of this Country in particular. Its more immediate 
design in the first instance was to constitute an appropriate Mantzssa that 
might be added with much advantage to the publication on British Birds 
by the same author, which has been so long favoured with public coun- 
tenance and encouragement. But the first outlines of this design have 
been since extended, and itis now presumed it may be consulted with 
advantage, as well by the readers of other Ornithological publications as 
by those ofthat Work in particular, to which it was at first in contemplation 
to be devoted. This undertaking will not be less than 24 or exceed 36 
Numbers, and will be continued periodically from the commencement to the 
completion of the publication, To prevent disappointment, as the num. 
ber of copies provided will be in a material degree governed by the imme- 
diate demand, Subscribers are requested to forward their orders as early 
as possible to their respective Booksellers,—Orders are received by Messrs. 
Rivington, St. Paul’s Church-yard, Waterloo-place, and 148, Strand; 
Messrs. Longman and Co. Paternoster-row; Sherwood, Gilbert, and Co. 
Paternoster-row; Simpkin and Marshall, Stationers’ Court; and every 
other Bookseller in Town and Country. Subscribers desirous of plain 
Copies must give explicit orders for such. 
: NATURAL HISTORY of BRITISH BIRDS. 
A Series of Coloured Plates, with appropriate Descriptions of such rare 
species of the Feathered Tribes as inhabit the British Isles, and have been 
unavoidably omitted in the above-mentioned work, is also in a course of. 
preparation, and will shortly be produced in Parts or Numbers periodically.
