published, although it has been reprinted times out of number ; 

 and to bring such a comparatively venei'able work quite up to 

 date would mean rewriting it almost entirely. This Dr. Bousfield 

 has, we think wisely, avoided, and, while making some very 

 necessary corrections and additions to the preliminary part and 

 the sections relating to preserving and mounting, he has left the 

 descriptive portion mostly untouched, except where the advance 

 of knowledge has made alteration imperative. The first chapter, 

 however, is partly, and the second, third, eleventh and twelfth 

 entirely new ; and the reviser has also given some fresh matter 

 amongst " Pond Life," including two new plates from his own 

 drawings. The twelve original plates by Tuff en West are, of 

 course, unaltered, and except that they are naturally not now 

 quite so sharp as in the earlier impressions, remain amongst the 

 best delineations of microscopic objects in any popular book. 

 We have noticed but few errors of any importance, although 

 " go^T ^®"^^' " ^^ ^^^^ ^^^® ^^ *^^ Palmellacese, but one of the 

 chromogenous bacteria, allied to, if not identical with. Bacillus 

 prodigiosus ; Pediastrum is not a desmid ; Bacillaria imradoxa is 

 hardly a common fresh-vxiter form ; and we greatly doubt if any 

 desmids can now be obtained " from a little pond on Blackheath." 

 In all probability the revised work will continue to be as popular as 

 ever with the class for whom it was originally written. — G. C. K.

Even microscopists, we presume, are not entirely free from the 

 human frailty of desiring to know, on occasion, " Who's Who," 

 and in the volume for 1900 they may find a very copious, if 

 condensed, biographical epitome of everybody who is anybody 

 in these islands. Beyond the information comprised in the title, 

 the book contains particulars of interest on many subjects not 

 otherwise attainable without considerable search : such as, for 

 instance, societies and their officials, newspapers and their editors. 

 Fellows of the Koyal Society, a copious list of abbreviations, the 

 proper pronunciation of our peculiar proper names, and a great 

 deal besides. In fact, " W^ho's Who " is indispensable on every 

 writing-table. Gr. 0. K.
