REMARKS ON THE WEATHER. 1842. 133 
DECEMBER. 
20", A great mass of scud covered eighth-tenths of the sky at 195 50™, when there was a 
pretty heavy shower ; it moved off so rapidly that there was only one-tenth of clouds at 20" 0™ ; 
a complete and distinct lunar rainbow seen at 19% 50™: cumuli and nimbi to S. and SE. 23. 
Scud or loose cumulo-strati. 2%. Cirrous scud, chiefly to W. 5". Loose cumuli. 
20%. Cirrous clouds and haze. 234. Scud: fine mottled, pure, and linear cirri above, point- 
ing N. 2. Loose cumuli: fine cumuli on the Cheviots, but the sky covered chiefly with fine 
cirri, radiating fron NNW. and from S. by W., principally mottled, but very thick to W. and NW. : 
linear to E.: hazy to W.: sky to E. 5%, Sky covered with cirrous clouds. 
20%, four-tenths of scud, the rest linear cirri, which covers almost all the sky : corona round the 
moon, radius three diameters. 28%. Scud: varieties of cirri above. 2. Cirrous scud: linear and 
pure cirri of the finest kind, like silken hairs, pointing from WSW. to ENE. 5%. Thick seud : 
cirrous clouds above. 
20 20—20 23. 20. Fine cirri and cirrous cirro-cumuli, moving slowly. 21". Fine cirrous clouds, mottled and 
in strata: cirro-strati. 22%. Fine cirro-cumuli: linear, mottled, and woolly cirri, the latter in 
little bundles lying in strata: woolly cirro-cumuli; some of the cirri extremely fine ; much of the 
upper cirri appears to radiate from NW. 23}. Cirrous clouds: cirro-cumuli of various sizes: finest 
linear cirri highest, pointing from WNW. ; the cirrous clouds are very thick in some places, and 
to the E. become like cirro-strati; the lowest cirro-cumuli are rather large and woolly : about 
235 20™ a few cymoid cirri were seen, and a few most beautiful mottled cirri. 
21 O—21 23. 0%. Large woolly cirro-cumuli moving slowly from WNW. : linear cirri lower, seem as if drifted 
from WNW.; thick towards horizon, cederaceous to SE. 1". The clouds present altogether a 
troubled appearance: the cirrous clouds have become quite thick, and like a semifluid: radiating 
from SE. and NW., lying in dark and light strips: masses of scud or loose cumuli creeping along 
S. horizon from about W. 2". Cirrous clouds thick and spread unevenly over the sky: scud to S. 
35, Some smoky scud very low from WSW.; scud or thick cirrous clouds above it from WNW., 
the cirrous clouds not so thick as at 2": some patches of sky: observed a patch of loose scud moving 
up from SW., which seemed to develop itself as if under the influence of two currents ; when about 
30° high, it showed the prismatic colours, something like diffraction spectra from irregularly striated 
bodies ; the clouds have a gray tinge ; other cirrous clouds above all. 4. The sky has a strange 
appearance: scud very low, very far below the highest cirri, moving in strings like smoke quickly 
trom SW.: higher seud slower from W. : linear cirri in E., and cirro-cumuli in zenith, &c. ; lowest 
cirro-cumuli gray, and moving slowly from about W., lying in bands from N. to 8. ; highest very 
fine, their motion not detected. 5. Scud principally: cirrous clouds seen above: sky in zenith. 
6%. Dark, but masses of scud can still be seen moving up from SW. 74. Quite dark. 8. North 
part of the sky dark; the south part has dark clouds near horizon, but lightens up to zenith, pro- 
bably cirrous haze: stars occasionally visible. 9%. Dark. 10. Scud, radiating from SE. : appa- 
rently cirrous clouds above. 11%. Clear in zenith: heavy clouds to E. 12". Clear streak in S. 
horizon: patches of sky to W. and in zenith. 18. Light clouds in zenith. 14*—155. Dense 
clouds to SE. and NW. 16%. Light clouds on N. and E. horizon; the rest of the sky covered 
with dark lowering scud. 17%. Dark clouds, except on N. horizon, 18"—-195. Cirrous clouds 
on horizon. 20. Sky covered with heavy clouds, especially on horizon. 21". Scud: heavy clouds 
on SE. horizon. 22%, Scud: cirrous clouds. 234. Scud very low and moving quickly from SW. 
patches of sky : cirrous clouds seen above. 
0*. Scud moving rapidly. 15. Scud: cirrous clouds. 2%. Scud: loose cumuli on E. horizon. 
3", Heavy rain: clear to N. 4%. Sky clear, except where cirrous cumuli skirt the horizon on all 
points but NE. 5". Scud: light rain, 6%—74. Scud, &c.: dark. 8". Clear in zenith. 9". Scud. 
10%. Light rain. 
20". In a few minutes rain, and the sky became nearly overcast: sky on SE. horizon: cirro- 
stratiseen there. 23%. Scud, in strata to SE.: a few linear cirri: rain freezing on the palings, &c. 
2h, A mass of cumuli to SE., and on NW. horizon. 5%. Loose-edged cumuli, having a cirro- 
cumulous disposition, moving quickly. 
205, Scud and cirrous clouds. 23%—2, Clear: a few cumuli on NE. horizon, and on Cheviot. 
54, Thin cirrous clouds, with a cirro-cumulous disposition. 
20%, Sky covered with a thin watery haze, which makes a sort of oblong halo round the moon : 
light rain. 23. Cirrous scud: woolly cirri above: portion of a rainbow seen: rain here lately : 
raining heavily on Cheviot. 2. Homogeneous scud : cirrous clouds above: light rain. 5®. Cirrous 
clouds: mottled, linear and woolly cirri, and loose cirro-cumuli:; sky nearly covered with fine cirri.
