128 NATURAL SCIENCE [February 



American Geologist. V. The most useful text-books and hand-books. 

 The palaeontological list includes Gaudiy's " Essai de pak'ontologie 

 philosophique," and Von Schlotheim's'" Petrefaktenkunde," but neither 

 the " Paleontologie Frangaise " nor Goldfuss' " Petrefacta Germaniae." 



VI. List of public and private geological, etc., collections in Germany. 



VII. Address-book of German geologists, mineralogists, and palaeon- 

 tologists. This includes addresses of people in 8t Petersburg, Vienna, 

 Holland, La Plata, East Africa, and — no, we cannot find China. 



VIII. Short report of the Seventh International Geologists' Congress 

 at St Petersburg. Short it is, but finds room for many errors. IX. 

 Talile of formations, according to H. Crediier. A correlation-table 

 would have been some use, or even a detailed list of German terranes. 

 This is useless. X. Declination-table for 1897. XL Table of 

 measures of length reduced to the metric system. XII. Specific 

 gravities of many elements, minerals and rocks. XIII. INIap-scales. 



A smaller percentage of error, a bringing up to date, a stronger 

 flavour of internationality, the omission of the diary and blank pages, 

 and a reduction of price, would ensure a large sale for this publication 

 in future years. A complete address-book of geologists comparable 

 to Friedliinder's admirable " Zoologisches Adressbuch " is a want of the 

 day ; so also is a complete list of geological periodicals, such as that 

 which used to appear in the defunct " Geological Record." Dr Keilhack 

 may be commended for his attempt, and recommended to try again. 



Birds as they Live 



With Natuke and a Camera, being the Adventures and Observations of a Field 

 Naturalist and an Animal Photographer. By Richard Kearton. Illustrated by 

 180 pictures from photographs by Cherry Kearton. 8vo, pp. xxi. 368. London, 

 Paris, and Melboirrne : Cassell & Co., 1897. Price 23s. 6d. 



This volume has been written to show the experiences of Mr Kearton 

 and his brother when searching for and obtaining those beautiful 

 photographic portraits of British birds so familiar to our readers. We 

 sincerely hope that the author and the artist have not laid the seeds of 

 a rheumatic old age, and that one result of their joint productions will 

 be their enfranchisement from the toil for daily bread, with the con- 

 sequent advantage to science which would undoubtedly accrue. The 

 first 134 pages of Mr Kearton's book deal with St Kilda, whither the 

 brothers journeyed in 1895, to study, among other things, the St Kilda 

 wren {Trorjlodytcs 'parvulus). Of this bird he has given photographs, 

 together with its nest, and noted the peculiarities it shows in com- 

 parison with the wren of the mainland. Puffins, fulmars, gannets, 

 shags, and many other birds are delightfully illustrated in this part of 

 the volume. Chapter IV. relates the author's experience of game- 

 keepers, their friends and foes, and is illustrated by pictures of various 

 unfortunate animals in gins, and other traps. Chapter V. treats of 

 nests, eggs, and young, and here it is that the photographer scores 

 his triumphs ; the beautiful little pictures of the coal-tit and the wren 

 entering her nest are the perfection of careful and patient photo- 

 graphy. Further chapters deal with catching song-birds on Brighton 

 Downs, duck-decoys, and the various methods employed by the 

 brothers Kearton in cliff-climbing and descending, and in securing 

 their photographs.
