On Atmospheric Disturbances, and on a remarkable Storm at Bombay on 
the 6th of April 1848. By Lieut-Colonel Sykes, V.P.R.S. 
Numerous are the expressions of surprise in England at the extraordinary cha- 
racter of the meteorological phenomena since last year. Mr. Glaisher of the 
Royal Observatory, Greenwich, in remarks on the weather during the quarter 
ending the 31st March last, says, “The weather during the past quarter has been 
remarkable in many respects. The daily temperature has been above the average ; 
yet there has been exceedingly cold weather between the 20th and 26th January ; 
and the temperature of the preceding quarter was in excess to the amount of 3°-4. 
The mean temperature of evaporation and of the dew-point above the average; the 
mean weight of water in a cubic foot of air of the same value as for the preceding 
six years. The quantity required to complete saturation 0°47 of a grain; the ave- 
rage for the preceding six years being 0°36 of a grain. The barometer was 07132 
below the average of seven years and the readings remarkable; and the great fluc- 
tuations in the readings appear to have been general, and differing from any period 
since 1800.” A sympeisometer in my house in Albion Street, Hyde Park, in De- 
cember last, fell 1 inch in twenty-four hours without a storm; and I have frequent 
records of rain without the sympeisometer being moved. A correspondent of the 
Times, in a letter dated Bermondsey, 7th Dec. 1847, speaks of the sudden and extra- 
ordinary changes in the atmosphere, and adds that his barometer, which stood at 
29°92 at 11 p.m. Sunday, 5th Dec., had on Monday the 6th, at 8 a.m., sunk to 
28°92, a difference of 1°2 inch in nine hours; and at 12 o’clock Monday night of . 
the 6th, it stood at 28°54; a difference of 1:38 inch in twenty-five hours, the air in 
that interval having been relieved of pressure at the rate of 326 lbs. on every square 
foot of superficial area. Magnetic instruments also have shown unusual disturb- 
ances. The fall of rain has been nearly double that of the preceding six years, and 
2% inches above the average since 1815. The range of a protected thermometer was 
from 71°°5 to 15°°7 or 55°°7 ; but a thermometer on the grass at Durham fell below 
zero; and on the 12th of July preceding it stood at 87 in the shade in London. 
In the north of Scotland in January, correspondents wrote, ‘“‘ We have had the 
extremes of weather.” Strange as it may appear, two gentlemen, Mr. Stericker and 
Mr. Whilburn, were frozen to death in September in Invernesshire. Short intense 
frosts and rapid thaws characterized the winter in England. At Madrid, in January, 
the cold was intense, yet in Lancashire there were some fresh sprigs of hawthorn 
3 inches in length, and leaves of the honeysuckle open; and the primroses and fox- 
gloves were as much advanced as if it had been the month of March; and the wild 
fowl, which usually pass in November, did not pass until the middle of December. 
On the 12th of December, near Penzance, four whirlwinds occurred, unroofing 
houses and overturning furze and turf-ricks, and carrying with them great quan-
