The Liverworts, British and Foreign, by Sir Edward Fry, G.C.B., and 
Agnes Fry. London: Witherby & Co. Pp. VIII. and 74. 1/6. 
This little book is intended as a companion volume to ‘ British Mosses,’ 
by the same author, and follows a similar plan, his object being to excite 
an interest in these lowly, but interesting plants. The forty-nine illus- 
trations are the work of his daughter, Miss Agnes Fry, and serve to show 
the more important structures met with in the different groups. After 
describing a thallose and foliose liverwort, chapters follow on the Ricciex, 
Monoclee, Anthoceree, Marchantiee and Jungermanniew, dealing with 
the more general characters of the groups. Other brief chapters deal 
with modes of reproduction ; Elaters ; Odour and Water Supply ; Alterna- 
tion of Generations; Classification and Distribution. The work is not 
intended for the specialist, and is written in the main in non-technical 
language. In attempting this great difficulties are encountered, and we 
think it would be better to explain and illustrate clearly the more impor- 
tant technical terms, and use them than try to find substitutes which are 
often misleading. To give only one or two examples: On page 4, he 
refers to the ‘ Archegone, or fertilized female cell’ though on page 7, he 
says the archegone ‘ consists of the ovum or female cell, and a flask-shaped 
vessel containing it.’ Rhizoids are usually referred to as ‘ rootlets’ and 
‘ root hairs,’ terms which have a definite botanical meaning, and ought not 
to be applied in this loose way. It is by such usage that they lose their 
significance, and render necessary still more technical terms which it is 
desirable to avoid.
