Professor Gibbs, of the Charleston (S. C.) College, has published in the Charleston Courier some speculations and observations on the great August storm. He says that similar storms have occurred with more Qi less violence, at different isninta in the same general range, for the last three years, on very nearly the same day of the same month. Anticipating the advent of the one this year, he kept a meteorological register ; and distinct evidence of its approach was given by the barometer on the 23d of August^ four days before it reached Charleston. Observing this, he pre'vented some friends from going on a sailing excursion, who would have otherwise been lost. After some statements as to the variations of the barometer, he says the course of the storm may be derived from the follqw-ing facts obtained from the journals, though they are not sufficient to assign with great precision .the path ol the centre of the storm, ! regarded as a revolving and progressive at-| mospheric disturbance:— At Key Westthe, storm prevailed during the 22nd; the wind at N. N, E., shifting to E. S. E. At Mobile, on the evening and night cf the 25th and the morning ofthe 26th, until noon; wind from S. E., shifting to S., then to W., to W. N. round to N. At Pensacola, storm severe on the 25th and 26th, wind E, then S., then W. In upper part of Georgia, heavy fall of rain on the night of the 26th and morning ofthe 27th. At Charleston, high wind on afternoon of 27th and until after midnight; wind S-, very little rain. 1 At New York, violent wind on the night of the 28(h and 29th; course of wind not given. At Boston, storm during the 29th; course of wind not given; fall of rain in that region 3 inches. From tliese facts Prof Gibbs infers that the centre of this storm, originating east ofthe Island of Cuba, passed over the northern portion, .or perhaps the middle of that Island, pursuing a tract nearly westward, reaching MataDzas about noon on the SSd; tllence curving towards the north in a semi-circular path through the'eastern part of the Gulf, at the rate of about ten miles an hour, reached Mobile about midnight of the 25th and 26th, or a little later, thence' northwardly, north-' north-easterly, and north-easterly through Alabama, northern part of Georgia, near Tennessee and North Carolina line, into Virginia, reaching the interior about noon on the 2Bth; thence north-easterly to New York, at midnight on the 2Sth, and to Boston at noon on the 29th, its velocity during the terrestrial part of the course being trom twelve to fifteen miles per hour, and taking just one week for its travels IromMatanzas to Boston. [The storm commenced in New York at 3 P. M. on the 2Bth August, and it was most severe between 7 and 10 P. M. It commen-eed to blow from the south, Wns in the east at 7 o'clock, continued in that quarter for five hours. It shifted to the north, and was in the west the next morning. The rain came not in drops but in sheets. The storms around New York are mostly rotary, and the rain comes either from the south or east.
