246 Meteorological Observations 



Feb. 26. — Haze in the mornins, fair day with various 

 clouds, and very clear at night. W. 



Feb. 27. — White frost, features of cirrostratus and others, 

 followed by a rainy afternoon, but a fair night. 



Feb. 28. — Frosty morning and hazy; fair day, cumuli, 

 cumulostratus, and cirroeuniulative masses above ; a sort of 

 vapour intervened, increasing in density ; at night showxrs 

 and increased temperature. 



Feb. 29. — Foggy early, then loose ill-defined cirri; above, 

 cumulus and cumulostratus; much cloud in the after- 

 noon. S. 



March 1. — Cumulus and cumulostratus, subcirrocumu- 

 lative masses above; in the evening petroid cumulostrati 

 rose in mountains all round, and cii-rostruti increased in 

 density, swelled downwards, inosculating, and threatening 

 nimbification ; a long vertical band of yellow light ap- 

 peared above the sun, occasioned probably by refraction 

 through a thin diiFused cirrostratus. Wind rose at night. 



March 2. — A north wind prevailed all day, with cumulo- 

 stratus, and occasional forniatiou of nimbi, which gave 

 light showers of snow and hail : clear night. 



''March 3. — Hoar-frost and overcast sky, followed by 

 small rain; very dark at night. S. 



March 4!. — Misty, followed by small rain; fair intervals 

 during the night, with a brisk breeze S.W. and N.W. 



March 5. — Clouds in different altitudes; sunshine at 

 times; a breeze from N.W. ; during the day nimbification, 

 or at least that state of density near approaching to it, was 

 conspicuous in many places. Cirrostratus spread far and 

 wide, in the evening threatening rain. 



March 6. — Rainy morning early, when it cleared ; masses 

 of cumulus floated along in the wind as usual, and in a re- 

 gion much higher appeared the cirrus, in some places 

 stretched along in bands, in others ramifying in many di- 

 rections; here wavy or like granulations, there disposed in 

 tufts; in short, it presented all those various and ever- 

 changing figures which I have often before had occasion to 

 speak of, as denoting a great irregularity in the distribution 

 of the electric fluid, to which this cloud appears to serve as 

 a conductor. The cirrocumulus also formed in many places. 

 Dark cloudy night. 



March 7. — Fine morning, and a breeze from W. Flocks 

 of loose cumulus float in the wind ; cirrostratus stretched 

 along rather higher : still more lofty the cirrus exhibits itself 

 luider a variety of changing forms, forming here and there 

 cirrocumulus of multiform appearance. During the day
