large species of a dull red colour, with very long tentacles 
trailing behind it as it drifts with the tide, is by far the worst, 
and the effect of its ‘‘thread-cells’”” on some skins is serious. 
Rubbing with whisky or chloroform is said to be the best 
remedy. The C&rysaora is a pretty species, with black and 
yellow spots on the margin of the disk or ‘‘bell.” I was stung 
by one of these while bathing at Colwyn Bay, on July 26th, 
1868, on the fore-arm. The pain was very acute at first, but 
went off entirely in less than half-an-hour. Of the other two 
common Acalepha, I have tumbled Rfzzostoma pulmo about while 
bathing, without feeling the smallest unpleasant sensation. 
This is the large species, with a deep bell, having somewhat 
the appearance of ground-glass of a more or less blue colour, 
and short thick tentacles. The fourth species, Aurelia aurita, 
which may be known by the four violet rings seen through the 
transparent colourless disk, is also, I believe, quite harmless. 
These facts are worth mentioning, as many people are deterred 
from bathing without cause, when these two last species are 
abundant. A: O!W.

THE CLIMATE OF CHESTER. 
By A. O. Waker, F.LS, 
The District adopted by the Chester Society of Natural 
Science, comprising as it does the sea-coast of Flintshire and 
Denbighshire, and reaching to the S.W. corner of Cheshire, 
has, for its area, a very varied climate. In the former portion 
the close proximity of the most mountainous portion of N. 
Wales on the S.W., and of the sea on the N.E., has a very 
marked effect in modifying it; while in the latter the climate is 
much the same as that of the central area of England generally. 
The climate of the coast has been dealt with in another paper 
in this number, and as we are without accurate information as 
to temperature and rainfall for the extreme south-western 
portion, I shall confine my remarks to the City of Chester. 
I may, however, here refer to an excellent paper (‘‘ Twenty-five 
Years’ Rainfall in Wirral”—Phillipson & Golder, 1889) by 
Mr. REGINALD BUSHELL, in which much valuable information 
will be found on the Rainfall in Cheshire. 
The Climate of Chester itself may be taken as intermediate 
between that of the coast and of the interior. The rainfall is a 
moderate one, but the average number of days on which rain 
falls is large in proportion to the amount of rain. Extreme cold 
is rare, the lowest temperature recorded of late years being that
