Doubleday. Page & Co., tgoz.
Mr. Dugmore's well-known nature phor tographs are a sutficient guarantee of his fitness to prepare a manual nn methods in nature photography. and he has placed the lesson of his own experience clearly before his readers. There are chapters on the outfitI exposing, developing, etc., photo» graphing birds and their nests. animals. reptiles, insects, tish. trees, shrubs and flowers, all so well illustrated as to show that the atrthor practices what he preaches. Particularly would we call attention to the photograph of the Woodcock racing page 22, which. made with an isochromatic plate and a ray filter, antl printed in sepia. is as beautiful and satisfactory a picture of this bird on its nest as we ever expect to see.
The photographs of reptiles. fish, etc, are equally good, and serve to confirm our opinion that Mr. Dugmore is the leading nature photographer in this country. A slip on page 7 makes a decrease at one-half in the diameter of the diaphragm. talls tor only twice. instead of four times as long an exposure, and may lead the amateur into difficulty if it he not correctedt—F.

THE pavements-r m: Coma ru FINITIVE FEATHER. By R. M. Bull. Mus. Comp Zoo|.. xl. . pp.146>186.pll. reix. Oct., 1902. Ornithologists constantly deal with the
color of birds’ plumage. btrt the character
of the color, whether it he title to pigments. featherstructure or both, are matters to be determined by the histologist and physicist.
The ornithologist can describe results. but
a determination of the prot~esses which have
brought them to pass requires a special train~
ing and knowledge at technique. such as few ornithologists possess, It was therefore exceedingly fortunate that Dr. Strong’s in- terest in birds should have let! hiln to de- vote portions of two years, while working
in tlte Harvard Zoological Lahorato study of the colors of feathers. The result» of his labors form a contribution to science of the first importance and are of especial interest to students of birds.
It is not possible at this time to present even an abstract of Dr. Strong‘s researches, but we may at least state that they not only
to a
revealed no evidence of repigmentation of a grown feather or ot a change in the t-olor of existing pigment, hrrt induced him to her lieve that changes of this character are not possibletil“. M. c.

'I‘he birds of the Bahamas. >0 far specimens are concerned, are well known; btrt few of the many naturalists who have
visited these islands have ltad Mr. Bonltote‘s opportunities to study Baharnan ltirtls in their haunts. His ' Field Notes,’ therefore, form an acceptable and important mn- tribtttion to otrr knowledge of Ballanran bird-life.
Six excellent photographs front nature of birds and birds‘ nests add not a little to the interest and value of this paper. the picture or the Noddy on its nest being an especially good hit at him photographyfir. M. (r.
