200 BOTANICAL INFORMATION. 
tracing which the plants are viewed collectively, with reference 
to each other and to their places. A first volume will de- 
scribe the Botanico-geographical features of Britain. Suc- 
ceeding volumes will compare the botany of other parts of the 
globe with that of Britain. 
2nd. Areas of British Plants—intended to show how far the 
various plants have been ascertained to extend over the sur- 
face of Britain and other parts of the world; each species 
being here taken singly, in rotation, and traced through Bri- 
tain and the rest of the earth’s surface. A first volume will 
show the Topographical Areas; the species being traced 
through those eighteen Districts of Britain, which were ex- 
plained in the discontinued edition before referred to. A 
second volume will be devoted to their Geographical Areas; 
the species being traced through larger sections of the 
earth generally. : : 
3rd. Localities of British Plants—intended to bea compila- — — 
tion of local lists and localities; the precise plan of this 
work being left undecided at present. E 
(N.B. It may be well to mention here, that manuscript 
localities are no longer wished from other botanists, unless 
they can be accompanied by specimens in confir mation.] 
It will be more easy to understand this proposed change in 
the arrangement of the subject, after glancing over the sub- 
joined pages, which are given as explanatory examples of the — — 
different volumes.. The “ Topographical Areas" will probably Wa 
be first ready for press; and this will be followed by the . 
* Botanical Geography of Britain." Some further delay be- 
comes unavoidable under the change of arrangement, which 
makes it necessary for all the Orders to be equally advanced; 
one as another, before the species of any of them can be 
printed. The former plan might have produced the better 
work in the end, if all the Orders could have been completed; — 
but with great uncertainty of completion, it seems more ad- 
visable to make each volume a whole by itself. Should the - 
author's labours be terminated abruptly, even after printing 
only a single volume, the curtailed work, though rendered less
