The appearance of an unpretentious work dealing with mosses 

 and hepatics, and practically devoid of technical terms, strikes 

 one rather as a novelty. The above artistic little volume is 

 certainly calculated to arouse enthusiasm in the subject with 

 which it deals, this being a remark which we should be very 

 chary of making with regard to the majority of works dealing 

 with cryptogams. It professes to be nothing more than an 

 introduction, but it is a sound and thorough one, and eminently 

 practical. The chapter on the collection and preservation of 

 specimens is particularly useful. Unlike most specialists the 

 author seems to be extremely particular in the matter of the 

 perfection and " finish " of his slides, regarding air-bubbles as 

 veritable bogies and sparing no pains to get rid of them. We 

 are rather surprised that he does not advocate the use of the 

 air-pump, which will generally induce even the smallest and most 

 artfully concealed bubble to reveal its whereabouts. Mosses and 

 Liverworts ought to have decidedly beneficial influence in popular- 

 ising the study of its title-subject, and we wish it success.

To recommend a work of this kind to a diatom enthusiast is 

 somewhat upon a par with recommending nuts to a monkey. 

 Perhaps, however, we may be justified in mentioning its existence
