470 Meteorological Observations 



peared confused flimsy cirri with cirrostratus, aimulostralus, 

 and fieecv curnuhis \n successively lower regions. A bright 

 meteor appeared about halt" past ten l\ M. 



Oct. 31. — Clear morning, with a line oF cirrostrafm east 

 and west, followed by much cloud showing features oi' cirrus 

 and cirrncumulus with cinnulwi below, and hazy air. The 

 temperature increased at night, with wind and rain from 



s. vv. 



Nov. 1. — Wind and rain from S.W. very warm. 



Nov. 2. — Long and gentle showers from S.W. various 

 clouds in the intervals; high wind by night, which blew 

 over large masses of fleecy cumulus. 



Nov. 3. — A strong wind from S.W. in the morning 

 blew over large masses oi' ci/muius and anmdostratus; thrflugh 

 the breaks cirrus appeared in a lofty station ; as rhe day ad- 

 vanced the wind fell, the quantum of cloud decreased, and 

 a sort of irregular confluent cirrocmnulus became most pre- 

 valent ; in passing to tb.is cloud the cirrus presented various 

 appearances. Some brilliant meteors at night. 



Nov. 4.-'^ — Showers before light; fair day; a shower 

 about three in the afternoon, petroid cumuli intersected by 

 cirrostratus and others. 



Nov. 5. — Wind and rain from S.W. all the morning; 

 about three o'clock it became fair and calmer, and the 

 night vias clear with some light confluent cirrocumulative 

 clouds. > 



Nov. 6. — Calm misty morning followed by much rain; 

 it held up for several hours during the day, but returned at 

 night with light gales from S.W. 



Nov. 7' — Fine dav and cooler than hitherto; cirriis spread 

 about in loose masses; also in some places in tufts; fea- 

 tures o't cirrocumulus appeared; and also cuvnilus. A lit- 

 tle before nine a large meteor was seen by several persons 

 in the neighbourhood : its motion was irregular. Wmd W. 



Nov. 8. — Kain more or less all day, with calm air. 



* In the progress of nimbificaiion the following- phenomena may be fre- 

 quently observed : The iitriis losing its cirriiorm (igurt becomes a confused 

 and dense veil s'velling downwards to meet ntmidiis below, which rises ir- 

 regularly upwards ; but the charige to (uinutuslislus precedes visible inos« 

 culation: aUer the nnnlnis has formed, a crown of cirrose structure maybe 

 seen exiending upwards as if conducting electricity from an upper region, 

 while the shower is nourished from below by fleecy cnmali, which float un- 

 der and become lost in it. 



I have observed that v.hcn ntnnili pa's to cumxih'.'jnjti^ they move much 

 slov.er though ii. the srime wind: Is :his to be attributed to their increase 

 of density iii proportion to the surface they present to the v.ind ?
