graphy, and illustrates it largely by lists of plants peculiar or charac- 
teristic of the several spots noticed. We have not space to transfer 
these interesting remarks and lists to our pages, but feel sure that our 
readers. will peruse them with much pleasure in the book itself. 
rt the third, Botany, is a complete and elaborate local flora of 
North Yorkshire. The country is divided into nine districts, and the 
plants of each of them are recorded in the same manner as in the 
Floras of Hertford, Cambridgeshire, and Essex. Mr. Baker endeavours 
to decide the claims of the plants to be considered as (1) natives, (2) 
colonists, (3) denizens, and (4) aliens, and add a few (5) as incognita. 
We doubt the possibility of doing this to any great advantage, even after 
the labours of Mr. Hewett Watson with that object. The author seems to 
have followed the teaching of that eminent botanical geographer with as 
much success as could be expected. It is pxotable that fei dip 
used in some other books may be better, 
viz. (1) native, (2) possibly introduced, (3) probably ii pe 
(4) certainly introduced. But even on the latter plan the cases where 
persons will differ as to the position held by plants are very numerous. 
The range in altitude through which each plant is found seems to have 
been carefully observed, and forms an interesting feature in the work. 
The country is well suited for it, the stations extending from the level 
of the sea to an elevation of 2580 feet. The number of species of 
flowering plants, Ferns, Zguisetacee, and Lycopodiacee, is summed up 
as follows :— 
= Classifying the plants of North Yorkshire according to their categories of 
citizenship, as in the list now completed, we obtain the following result :— 
Natives 10,5199 noe og 
Colonists eqn ee

“ Of the 992 species of the three higher grades of citizenship, 948 are ascer- 
tained as plants of the Lower, 413 of the Middle, and 126 of the ripper zone. 
A more detailed classification of the species according to their altitudinal range 
will be found at p. 188; and an attempt at a classification of the native 
according to the plan of their distribution in North Yorkshire will be found .
