Volcanic Eruptions and Hurricanes. 239 
’ 
vember, (the latest date of the published observations), we 
find a succession of N.W. and S.E. gales; thus :— 
Ocrozser 7, N.W. gale; 8th to 11th S.E. gale; 9th, very 
cold, and an immense quantity of rain fell; 12th and 18th, 
N.W. fresh; 14th and 15th, 8.E. gale; 16th, a shock of an 
earthquake of greater force and duration than any we have 
hitherto felt in the colony. Wind 8.E. to N.W. during the 
night, blowing a fierce gale, with heavy rain; 16th to 2ist, 
strong S.E. gale. On 19th, very strong 8.E. gale, and at 
5 a.m. a strong shock ; 22nd to 26th, wind N.W.; 27th to 
29th, S.E., fresh; 30th to 3lst, N.W., strong gale, &c. 
The barometrical observations made six times a day on 
board Her Majesty’s ship Fy, at Wellington, from the 15th 
to the 28rd October, are given in the New Zealand Spec- 
tator. The curve is analogous to that already given, but 
ranges much higher, on account of the considerable difference 
of altitude between the position of the ship and that of Mr. 
Chapman’s house. On Wednesday p.M., at the time that the 
curve shows the centre of a cyclone, Captain Oliver, of the 
Fly, writes, ‘‘wind round and round the compass ;” mid- 
night, a gale at south.” 
From the 16th to the 24th October there occurred upwards 
of 1000 shocks. On the 18th November it is stated that, 
“taking the whole of the shocks during the five weeks, only 
four have occurred of sufficient force and duration to do 
damage, though at times as many as fifteen have been counted 
in an hour, and perhaps more than one hundred and fifty in 
the twenty-four hours.” During November the number of 
shocks ranged from two or three to seven or eight a day. 
Now it appears to me that such a continued succession o1 
small shocks implies the immediate proximity of an active 
volcanic orifice. 
Humboldt felt periodic and very regular shocks of earth-
