126 REMARKS ON THE WEATHER. 1842. 



SEPTEMBER. 



and seen in the dark grayish-blue beyond, with a patch or two of the brightest blue sky ; the sky is 

 just seen through the scud in the zenith and to E. ; it is difficult to tell whether there is a bluish- 

 gray cloud or only the sky seen through the scud : raining : about this time the ends of a double 

 d h d h rainbow were seen. 



1 20 — 2 5. Scud. 6^. Small patches of greenish sky to SSE. : some low patches of scud from SW. : drops 



of rain. 



2 20 — 3 9. 20**. Thin scud sailing very quickly ; denser near horizon : ragged cirro-cumuli above moving 



very slowly ; sky in zenith. 23** — 5*^. Scud : light rain at 5^. 8** 40™. Three diflFerent currents 

 of air observed at present ; the highest carries loose patches of scud from W by S. ; the next 

 lower, larger and darker masses from NW by W. ; and the lowest, thin vapoury patches of scud 

 from NNE. ; the direction of the wind at the surface is NNE ^ E. (SW. at 5**.) ; the greatest 

 mass of clouds is from NW by W. ; the upper current is very slow ; in a few minutes the lowest 

 current nearly ceased, it was previously the swiftest : quantity of clouds 9-0. 



4 20 — 5 5. 20*^. Linear cirri and cirrous haze : thin cirrous nests. 23*^. Scud, &c. : cirrous haze seen near 



horizon : clouds moving very slowly. 2''. Thick scud. 5*^. Scud : other clouds above stationary, 

 or nearly so. 



5 20 — 6 5. 20*". Scud : cirro-cumuli. 23*^. Loose cumuli and scud ; the cumuli moving slowest. 2''. 



Cumuli and scud. 5*^. Large mixed cirro-cumuli and cumuli : sky on NE. and NW. horizon, on 

 the NE. it is light green ; clouds black to SE. 



6 20 — 7 5. 20^. Linear cirri radiating across the whole sky in feathered masses from the W. point of the 



horizon ; on the E. horizon the linear cirri lie N. and S. parallel to the horizon ; the feathers of 

 cirri extend from W. to 30° from E. 23**. Loose cumuli moving slowly : cirro-strati higher, 

 moving much slower : sky in patches : detached cumuli and cirrous haze on E. horizon. 2**. Loose 

 cumuli : cirrous haze and cirro-strati seen above stationary : sky in detached patches. 5^^. Thick 

 cirrous haze, through which the sun scarcely projects a shadow : thick banks of dark clouds here 

 and there : the clouds have a perceptible motion from S. by E. : stormy-looking. 



7 20 — 8 5. 20^ — 23*^. Scud : light rain. 2*^. Scud ; the sun's rays penetrating some openings. 5^. Loose 



cumuli and scud : linear cirri and cumuli above. 



8 20 — 9 5. 20*^. Scud : homogeneous : light drizzle. 23''. Scud. 2'^. Scud : cirro-cumuli : cirro-strati, 



like sheets of white paper to E. : dense cumuli round horizon. 5^^. Detached masses of scud or 

 loose cumuli : pinnacled cumuli and other clouds above moving much slower : cirro-strati on horizon : 

 very black to NW. 



9 20 — 10 5. 20''. Thin scud : cirro-cumuli above. 23''. Scud: cumuli, &c. above. 2^. Scud and cumuli : 



cirri like flames, radiating towards NW. and W. 5^. Scud and loose cumuli : cirro-cumuli above, 

 moving very slowly. 



11 20 — 12 5. 20''. Scud: cirrous haze near S. horizon; a few minutes before this the sky was overcast ; 



clearing off rapidly from W. : thick and dull to E. : wind rising : in a few minutes the sky was again 

 quite overcast. 23''. Scud : sky on NW. and NE. horizon, where cumuli are rising. 2''. Cumuli : 

 cirrous haze on S. horizon. 5''. Cumuli to W. : fine linear cirri, like pencils of the finest hairs, 

 the root being to E., pointing E. and W., and reaching over 75° in length from E. to past the 

 zenith ; they are visible over the whole sky, lying quite parallel to each other, and apparently 

 springing from a kind of reticulated cirrus, which forms a portion of the circumference of a circle, 

 whose centre is in the E. and radius 20° ; the roots of the cirri appear to move on this circum- 

 ference, the cirri apparently describing a greater circle : cumuli moving slowly. 



12 20 — 13 5. 20''. Very thick; appearing to radiate from N. and S. : cirro-cumuli in the zenith, and thick 



cirro-strati to E. 23''. Nearly homogeneous : some small patches of scud. 2'' — 5''. Large dif- 

 fuse cirro-cumuli : specks of sky here and there : the sun's rays through the interstices of the 

 cirro-cumuli project a faint shadow. 



13 20—14 5. 20'' — 23''. Scud : nearly homogeneous : patches of sky at 20''. 2''. A strip of sky on NE. 



horizon. 5''. Patches of sky to SE. and S. : cumuli on ESE. horizon. 



14 20 — 15 5. 20''. Thick mist, rendering trees invisible J of a mile distant: large loose cirro-cumuh. 



23''. Cumuli and large cirro-cumuli ; cumuli lower and moving quicker than the cirro-cumuli. 

 2''. Loose-edged cumuli : sky in patches. 5''. Very large cirro-cumuli : very black to NNW : 

 sky seen between the cirro-cumuli. 



15 20—16 5. 20''. Cirro-cumulous scud: different kinds of cirro-cumuli above: linear cirri still higher. 



23''. Cirrous haze : scud and cumuli : linear cirri to E. with small patches of cirro-cumuli : the
