BERMUDA IN PERIODICAL LITERATURE, with occasional refer- 

 ences to other works : A Bibliography, by George Watson Cole 

 1907. Pp. xii+275. " By far the greater part of what has been 

 written concerning Bermuda has appeared in various periodicals and 

 the publications of learned societies. These writings may roughly 

 be divided into historical and descriptive, and those relating to natural 

 history. Of history, properly speaking, little has appeared ; but 

 many descriptive articles have been written by tourists and others 

 who have visited those beautiful islands. Their geographical situa- 

 tion and subtropical fauna and flora early attracted the attention of 

 those interested in scientific phenomena. Soon after beginning this 

 work it became apparent to the compiler that the Bermudas have for 

 the past half-century been a favorite field of the zoologist, botanist 

 and geologist. Bearing this in mind, a special effort has been made 

 to render the record of their labors as complete 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 flora and fauna 

 of those islands." 



The scope of this work is sufficiently indicated in the above quota- 

 tion from the author's preface. Mr. Cole has made the bibliography 

 of Bermuda a labor of love for many years, and the number of titles 

 brought together here will surprise even those who have been inter- 

 ested in things Bermudian. The notes given under all important 

 titles amount to a digest of the papers. Thus in dealing with biolo- 

 gical articles, all species described from Bermuda are cited, and ex- 

 tracts are given to show what of interest any paper contains. To the 

 naturalist interested in Bermuda the work will take its place as an 

 indispensable reference book ; but Mr. Cole's delightful notes give 

 the opus a merit all its own ; it is really a readable bibliography.
