METEOROLOGICAL ABSTRACT. 211 



inary degree of warmth was maintained by a liit;h wind, that blew conftantly from 

 S. W. and S. S. W. bringing with it the air and temperature of the foiithern parts 

 of the Atlantic. This wind prevailed over fuch an extent of the ocean, and blew 

 with fuch violence, that it forced back, a fleet of Britifb men of war, after it had 

 endeavoured, in vain, for fix weeks, to make its pafl'age to the Weft Indies. 



It muft be remembered, that the great cold of the preceding winter was with 

 a wind N. N. E. and fometimes N. N. W which blew very moderately. 



On the 23d of January there was a hurricane from S. S. W. that blew down 

 trees and unroofed houfes : The barometer fell very low, and did not rife to its 

 ordinary height for more than ten days. 



In March the weather was cold, 3° below the middle temperature of February; 

 eaft winds prevailed, and the premature appearances of vegetation, produced by 

 the mildnefs of the preceding feafon, fullered a fevere check. April was more fa- 

 vourable ; but in May the weather again became cold, with eaft winds, remarkably 

 dry and parching. The grafs every where fuffered extremely from this month. 



On the 3Cth there was a hurricane at London, and at Portfmouth on the 31ft. 

 On both thefe days the barometer here was very low, 28.53, though the wind was 

 no more than a brilk gale at S. W. 



In June the mean temperature was not fo high by 2° as in ordinary fea- 

 fons. The wind, though weft, was ufually from the northern points of the femi- 

 circle. 



July was worfe than June, and its mean temperature 3° under that of a tole- 

 rable feafon. Great apprehenfions were entertained for the crops, which, without 

 the fine weather that fucceeded in Auguft, muft have been ruined. The heat ot this 

 month, which was at a medium about 61^°, was not fo remarkable for being great as 

 for being uniform ; the thermometer, for a great part of the month, was not below 

 63°, even in the night. There was a great deal of funfhine, and the wind almoft con- 

 ftantly W. S. W. 



The firfthalfof September was little inferior to Auguft. On the 21ft, the 

 wind, from the S. W. came round to the N. E. ; a confiderable fall of rain follow- 

 ed, and the weather became colder, and continued to be fo in Oftober : the medium 

 temperature of which was 3 degrees lower than the average. 



A SMART froft fet in on the 29th of November, and next morning the thcrmo. 

 meter flood at 26°. This froft continued till the loth of December, with an 

 intenfity very unufual fo early in the winter. On the evening of the 5th the ther- 

 mometer was at 21°. Between the loth and 13th the froft had almoft difappeared; 

 but it returned on the 14th with confiderable feverity, and continued till the 28th, 

 when it broke up entirely. The thermometer was at 19° on the 26th, and in many 

 places lower. The fame froft was felt in England, where there were local colda of much 

 greater intenfity, the thermometer, in fome places, having been as low, it was faid, as 

 — 10. A trad of very mild and open weather began on the 31ft of December.
