Bermuda in Periodical Literature, -with oc- 

 casional References to other Works. A 

 Bibliography by George Watson Cole. Pp. 

 ix + 275. Printed for the Author. 1907. 

 This volume contains 248 pages of refer- 

 ences and 24 pages of index; the references 

 are arranged alphabetically by publications, 

 the index by subject and author, thus pro- 

 viding easy access to the contents. Each title 

 is followed by a brief note which gives the 

 characteristic features of the article, and 

 these notes constitute a feature quite as valu- 

 able as the references themselves. 



On the last page is a list of references to 

 libraries in which a copy of the work cited 

 was found. By the choice of fonts and skill- 

 ful use of insets the various items of a cita- 

 tion are clearly difEerentiated to the eye, and 

 the page is made attractive. The range of 

 periodicals cited is very wide, and they cover 

 not only newspapers and magazines, but pro- 

 ceedings of learned societies. The range of 

 subjects is unrestricted, and taken together, 

 they comprise nearly all that has appeared con- 

 cerning history, description and natural his- 

 tory for the last fifty years. The last division 

 has been especially well done, for it became 

 apparent to Mr. Cole, soon after beginning 

 his compilation, that Bermuda has been a 

 favorite field for the geologist, the botanist 

 and the zoologist. In the preface he says: 



Bearing this in mind, a special effort has been 

 made to render the record of their labors as com- 

 plete as possible. In order to do this, references 

 are made to some works which are not periodicals, 

 mostly, however, by authors who have also made 

 contributions to periodical literature concerning 

 the ilora and fauna of those islands. 



The result of this special effort has been to 

 provide in one volume a reference to nearly 

 every addition made to the flora and fauna 

 since (and including) the Challenger expedi- 

 tion. The value of such a gathering to the 

 botanist and the zoologist can not be over- 

 estimated, and this compilation, moreover, has 

 proved to be exact and accurate at every point 



tested by the reviewer. Some idea of the 

 manner of treatment may be gathered from 

 the fact that nearly fourteen pages are re- 

 quired for the direct excerpts from the Chal- 

 lenger report, to say nothing of the entries of 

 articles appearing elsewhere on the Chal- 

 lenger material. The references on birds go 

 back to 1849 and come down to 1904; those 

 on flora extend from 1700 to 1906 ; those on 

 geology from 1833 to 1906. Moreover, the 

 index takes account of the changes in nomen- 

 clature (e. g., " Leptocardians, Goode (1877), 

 19. See also Asymmetron"), so that the dif- 

 ficulties due to this unfortunate obstacle are 

 minimized. 



While natural history is amply represented, 

 the other subjects are not neglected. Twenty- 

 four pages are given to citations from the 

 New Tork City daily papers and seven pages 

 to those from the London Times. The total 

 number of citations is 1,382. 



Taken as a whole, the work is a masterpiece 

 of bibliography. To take up the chronicles of 

 a somewhat remote island and set them down 

 in order in these days of wide-spread publica- 

 tion seems a task almost impossible to per- 

 form in a creditable manner, and a thankless 

 task when done. Mr. Cole's work is excel- 

 lently well done, and he will earn the hearty 

 thanks of every botanist and zoologist who 

 has occasion to use the volume. In view of 

 the forthcoming tercentennial celebration to- 

 be held in Bermuda next year, the colony may 

 well thank Mr. Cole for so handy a volume 

 of reference.
