REPORT —1854. 
from each of the eight principal point9 of the compass, and the mean force for each 
month. The author remarks that observers at several stations must either use very 
wrong estimates of the force of the wind, or their scale of comparison must differ 
altogether from that furnished by Dr. Lind’s wind-gauge. The discrepancy is so 
great between several of those he found recorded in the Registrar-General's Report 
and his own, that he was nearly induced to reject his own in toto as worthless, till 
he became re-assured by finding great accordance between his own and those of 
Greenwich. He then shows that, according to the directions given by theComnutw 
of Physics of the Royal Society, if we form an estimate for five places which he 
selects" from the Report for the first quarter of 1852, violent storms must have blown 
the entire time at all these places. At Southampton, the average pressure" '■ 
wind is something less than 2 lb. on the square foot. Table V. is a continuation o 
Table VI., published in the Report for 1851. It contains a comparative view of w 
climates of Falmouth, the most southern town in England ; Stone, near Avles Hm 
an inland place about the middle of the southern portion of England; torn, i ■ 
and far to the north; and Southampton, near the coast, but more she e 
Falmouth. Such comparisons as these the author considers most valuft *• 
valuable communication is also accompanied by an exemplar sheet for tne 
March 1854, to show the manner in which the observations arc made, » 
recorded. All the observed facts ore recorded in black ink ; all the rcuuc 
deductions from the fact3 in blue.

Examination of the Storms which have visited England and 
the years 1852, 1853, and 1854, with reference to the Theory oj 
Storms. By John 13. Nevins, M.D., Liverpool. fo |. 
Doubts having been started whether or not the rotatory character o s 
lowed them into high latitudes, the author was led to examine the A or pot 
of storms in England and Ireland for these three years, to ascertain t j o0 from 
they partook of the characters of cyclones, viz. having a progressive^ bgd , 
the west and south towards the east" nod north, at the same time tna ^ watc h 
revolving motion or whirl in the opposite direction to that of the “* rC cordd 
m these latitudes. The observations examined by the author wereJ'‘ os 8 „d at 
in Armagh by Dr. Robinson, at the Liverpool Observatory by M** , c - |t y of t 1 "' 
he Royal Exchange, London. Those made in Armagh register c'omp® 3, 
wind m miles for every hour, and the course to the nearest po» ut 0 , the coo^ 
IhoBe m Liverpool also register the velocity in miles for each hour, _; s ter t--' 
to the nearest two point* of the compass ; whilst those marie in Loniio ^ w tv

shown in detail in a table) by the arrival of the leading phases of tne ^Ir; 
in succession, first at the most westwardly, and then more and m r ^ A 
intervals from Armagh to Liverpool varying from one to t ' ve Armagh' lfc 
commencement and the height of the stem invariably arrived first * ho*; 
at Liverpool, then at London, after distinct intervals. It in some
