accurate, and friends are therefore asked to compare notes, 
when possible, before sending in lists. They are also asked to 
carefully name exact locality and date of each find. In all cases 
where the least doubt is felt, the specimens themselves should 
be sent for verification to the Rev. A. H. Nutting, Holy Trinity

Bulletin of the British Ornithologists' Club, vol. xvii. Report on the Immigra- 
tions of Summer Residents in the Spring of 1905. By the Migration Com- 
mittee of the Club. Illustrated with 32 maps. Witherby and Co. Price 6s. 
Though at a first glance 6s. may appear a high price for 127 pages octavo in 
a paper wrapper, directly we examine the thirty-two valuable maps of England 
and Wales by which this report illustrates the migratory course of the twenty-nine 
species investigated we see that this charge is fully justified. The proceeds of 
the sale of the report are, moreover, to be devoted to the continuation of the work 
of the Committee. The interesting conclusion is arrived at that two routes 
“appear to be taken by birds of passage through this country — the one from 
Devon and Dorset, through the West of England and North Wales, and so out of 
the country, and the other from Sussex and the south-eastern corner of England, 
probably up the south-eastern coast and out of the country from Norfolk, and 
possibly, from still further north.” 
Birdland Pictures : Twenty four Illustrations from Photographs direct from 
Nature. By Oliver G. Pike. Crofton Publishing Co., Brockley. Price 
3s. 6d. net. 
This is a beautifully printed portfolio of fine enlargements from Mr. Pike’s 
well-known photographs of bird-life. Each plate is about 9 in. by 7 in. and is 
accompanied by a page of letterpress. The subjects are chosen from various 
habitats, from the Razor-bill, Gannet and Puffin of the shore, to Owls, Blackbird 
and Whitethroat, and all are alike admirable. Three or four pictures of nests and 
eggs without the parent birds are included. The inaccessibility of many of the 
subjects seems to have necessitated the employment of a relatively small plate, 
and in its enlargement, whilst the bird is in accurate focus, the surroundings, 
such as foliage, are occasionally somewhat blurred ; but this, perhaps, as in the 
works of some great painters, serves but to enhance the effect of the bird-portrait.

While the complexity of the highest animals affords problems insoluble by the 
biologist, the simplicity of structure of those at the base of the series presents 
similar problems in a form which proves attractive by holding out good hopes of
