968 NEW PUBLICATIONS. 
The deficiency in the upper line of numbers, it must be borne in mind, 
is caused by the absence from Middlesex of a large number of character- 
istically maritime species. From the 826, the 58 species require to 
be deducted to represent the flora as it now stands. No doubt the 
county list is far more likely to be lessened than increased in the future. 
The remainder of the work is occupied by a series of interesting 
biographical notices of the older botanists who have contributed to the 
knowledge of the flora of the county. This is derived to a consider- 
able extent from unpublished material, the Sloane manuscripts in the 
British Museum being the prineipal source of fresh information. Mr. 
Worthington Smith has contributed a list of the Hymenomycetous 
Fungi of the county; the Rev. J. M. Crombie a notice of its Lichens ; 
and Dr. Braithwaite and the Rev. W. M. Hind, a list of Mosses and 
Hepatice. 
Compendium of the * Cybele. Britannica; or, British Plants in their 
Geographical Relations. By Hewett CorrRELL Watson. Part IT. 
Thames Ditton. Printed for private distribution. 1869. (Pp. 201- 
424.) 
It is just a year since we noticed (‘Journal of Botany,’ Vol. VI. 
374-377) at some length the first part of this excellent and useful 
book. Mr. Watson has carried out the intention he expressed in the 
preface to that part, and has not allowed 1869 to pass away without 
completing his ‘Compendium’ so far as the native species are con- - 
cerned 
In this second part, 880 species are treated in accordance with the 
formula of eight lines, which we explained in our notice of Part I. 
The amount of information comprised in each of these formule is 
really amazing, and each affords an excellent example of what may be 
effected by a judicious system of condensation and abbreviation 
It is quite unnecessary to recommend a book which must take its 
place as essential to the library of every British botanist. In a work 
of such extent there must be, of course, many points upon which any 
two individuals will hold different opinions; but, after all, the book is 
mainly a record of facts, and it is on this account that it is of so great 
value, and lays all students of our native flora under obligation to its 
author. = p. 348, in the list of counties for Wolfia arrhiza, 
us ' is erroneously entered for Kent.
