On the Cyclones af Tasmania, ke. 423 
7th. ‘The shower of burnt leaves, &c. reached New Zealand 
(Otago), on the morning of the 7th February. 
In Van Diemen’s Land, on the night of the 6th, a violent 
hurricane accompanied the hot wind. At Hamilton, the 
crashing and uprooting of forest trees was sublime—fences, 
palings, &c. were whirled in mid-air. The heat was intense, 
The whole of the “new country” adjacent to the Repulse 
and Gordon Rivers was in flames. 
At New Norfolk, property worth £1,000 was destroyed. 
A verandah was blown some yards into the air, and alighted 
on the house. 
Two seamen of the Aleméne, French corvette, were drowned 
at Hobart Town by the capsizing of a boat. The hurricane 
at Hobart Town was accompanied by vivid flashes of light- 
ning, but no thunder nor rain. 
In a hot wind the. thermometer will be a much more sen- 
sitive index than the barometer. ‘Though the hot wind was 
the proximate cause of the atmospheric disturbance on the 
6th February, yet the resulting phenomena, both on land 
and at sea, were undoubtedly greatly influenced by the 
immense area in a state of intense conflagration. The baro- 
metrical and thermometrical fluctuations were, therefore, the 
results of the combined action of the bush-fires and the hot 
wind. ‘The effect on the barometer of a hot wind alone I 
have shown by a curve of eighteen readings during fifteen 
hours, at Sydney on the 23rd and 24th of March, 1849. 
(Fig. VII.)* 
These comparatively inconsiderable barometric depressions 
tend to show that the atmospheric disturbance produced by 
a hot wind is not a Cyclone.
