in the discrimination of the more difficult forms,—Carex and 
Potamogeton, Orchis incarnata and O. latifolia, for instance. 
We also contemplate a brief introduction on the geology and 
physical geography of the county as bearing on the Flora, such 
as is given in all our best local floras. This extensive subject 
will be necessarily much condensed, but references may be 
given to a select bibliography. Mr. W. C. Lucy and Mr. Wrr- 
CHELL have kindly given aid and advice in this branch of our 
work. 
We believe our work will occupy altogether from 250 to 350 
pages, crown 8yvo. and that this size and form is essential to its 
use for field work. We propose that it shall include a thoroughly 
good map, giving my district lines, the surface geology, dis- 
tinguishing the Northern Drift and the Oolite Gravels, and as 
much topographical detail as possible. 
It may also be desirable to have lithographic plates from 
Mr. Harxer’s drawings of some critical forms. 
We hoped that our work might have been published by the 
Club, as the representative body of all branches of local natural 
history; but the necessity that our numerous observations 
should be placed within the reach of a wider circle of readers 
renders this impossible. We, therefore, merely ask the sup- 
port and co-operation of the members of the Club for our 
publication.
