 .—Sunday, March 24th, 1878, will long be remembered as the date of the capsizing of, with loss of about 300 lives, at four p.m., off , on the east side of the Isle of Wight. The violent but brief atmospheric disturbance which was the cause of this catastrophe appears to have advanced from the N.W., and reached the north of England about ten a.m. Taking a south-easterly course, snow began to fall at Leicester about 1:45, and was followed by a strong gusty wind, but in an hour all was over. The barometer here fell but little, from 29.599 at nine a.m., to 29.494 at 12:45, and 29.477 at nine p.m. The next morning showed a marked recovery—23.731. The following interesting notes will show that the squall was of a more severe character in the West Midlands. The situation of the Eurydice—but a short distance to the S.E. of high cliffs, behind which chalk downs rise to a height of 800 or 900 feet, will sufficiently explain the way in which the squall took the vessel by surprise. The squall advancing from the N. W., the vessel was screened from it until it burst down the steep slope of the land in full fury.

The following notes on the weather of March 24th, are from observers whose names will be found in the Meteorological Returns for March, in Connection with their respective stations:—, (Chesterfield.)—Lightning, with snow. .—A sudden dense storm of snow, covering the ground inches deep, with a violent wind. . (Cheadle.)—The snow squall which swept across England from N. to S., reached Wean about noon, and cleared off about 12 45. .—A terrible snow storm, of short duration, burst over here at 2 p.m. .—Thunder and lightning, with violent wind, accompanying a snow storm. , (Shrewsbury.)—Violent storm at noon; darkness and heavy snow, , (Bishop's Castle.)—The snow storm or cyclone was very violent here about noon, and was followed by a display of Aurora Borealis at night,, (Bishop's Castle.)—The squall struck here with one terrific gust at 12 noon. .—A severe snow storm with strong N.W. wind at 12 noon: lasted about an hour. Bar, 29.431 at 12¼; Temp. 35.5. .—The storm burst on us very suddenly from the N.W. at 1240, The barometer only fell two-tenths of an inch from 9 a.m., and quickly recovered, .—The storm struck here about 1 p.m. with the contrast in less than two minutes from bright sunshine to a perfect hurricane of wind, dust, and snow so thick and dense that nothing could be seen twenty yards off, was most extraordinary. It was all over and bright sunshine in about ten minutes. Bar, at 9 a.m. 29.84, at 1 p.m., 29.44. .—Snowstorm 12 to 12 30, then clear till 6 p.m. .—Rapid fall of Bar. Snow from 1.30 to 6.30 with squalls of wind.

Lepidoptera.—On April the 18th, on the banks of the Great Western Railway between Reading and Oxford I saw three specimens of C. Ednsa; also, one of C. Rhanni—E. H. Maycock.

The Harebell with White Flowers.—In 1875 I observed a number of white harebells on a bank in the parish of Dalby, on the chalk hills or wolds in the east of Lincolnshire. If I am in the same locality this Summer I will look for them, and can then answer the two last questions.—A. E. J.
