Recently published Ornithological Works. 355 
of the first part of their Journal, which we are sure, from 
our knowledge of the keen interest taken by the men of 
Hastings and the district in Natural Science, will be both 
interesting and successful. The position of Sussex is such that 
rare species from the Continent frequently visit its shores, 
while it is also well situated for observations on migration. 
Evidence of this is given in the present part by the article 
of Dr. N. Ticehurst on the Yellow Wagtails and the breeding 
in Sussex of Motacilla flava in particular, and that of 
Mr. Butterfield on British Birds obtained in the county, 
while the President, Mr. Parkin, contributes an interesting 
paper on Extinct Birds, with plates of the Dodo. 
36. Headley on Evolution. 
[Lifeand Evolution. By F.W.Headley. London: Duckworth & Co., 
4 
1906. 8vo. Pp. i-xvi, 1-272.) 
We are sorry that the subject of Mr. Headley’s book 
precludes us from giving a full notice of its contents, for 
in less than three hundred pages he gives an admirable 
exposition of the main facts of animal and plant life ina 
manner that is at once popular and scientific. The school- 
boys at Haileybury, for whom the lectures were originally 
written, are indeed fortunate in a master who so well under- 
stands their needs, but the book may be strongly recommended 
also to grown-up naturalists. wo chapters are devoted to 
Birds, in one of which the author traces, with the aid of 
many useful illustrations, the wonderful development of 
Reptile into Bird, and supplements his story with details of 
structure and notes on coloration, the senses, the breathing- 
powers, the temperature, and the powers of locomotion. In 
the following chapter the Flight of Birds is considered at 
length, with still further wealth of illustration, including 
figures and diagrams of the course of flight of birds, kites, 
and so forth, not to mention a toy flying-machine of the 
writer’s own construction and a flying windmill. Very lucid 
explanations are given of the facts that enable a bird to fly, 
poise, soar, glide, rise, alight, and steer.
