84 Extra METEOROLOGICAL OBSERVATIONS, APRIL 16—JuLy 31, 1845. 
ADDITIONAL METEOROLOGICAL NOTES. 
1845. 
da. oh. m. 1 
Apr. 16 11 Cirri radiating from about NE by E., but they are formed of bars lying NW by N. and SE byS.; — 
there is a circle of light round the moon of the usual dimensions of the halo, but the interior | 
of the circle is as luminous as the circumference ; the corona is not well coloured. if 
Apr. 21 16 10, Crepuseular arch, 7° altitude; sun’s upper limb visible at 17” 20™. 
Apr. 22 16 7. Crepuseular arch ; reddish vapour, 3° altitude ; bright yellow, 6° altitude ; white, 9° altitude. 
17 27. a Lyre watched till now, when 4 of the sun’s diameter is visible above the horizon ; had the 
eye been a little better cared for at first, I have no doubt but it might have been seen when 
the sun was completely above the horizon; the eye was kept upon the star by placing the 
eye, the star, and a corner of the Observatory in the same vertical. 
Apr. 25 11 Light on horizon to 8. } W., like from a fire. 13h 58™. Very bright to N by E., altitude 10°, 
as if the moon were shining through the clouds. 14" 6™. Bright-red glare, covering a cir- 
cular space of 10°; the reflection (?) is only from the upper clouds (cirro-strati ?) and there 
is a black patch in the midst of the glare: this is perhaps the reflection of a fire as it oceurs 
in exactly the opposite point of the horizon from the light seen at 115, 
May 1 5. Beautiful and vivid double rainbow, the extremities within 150 yards of the observer ; four re- 
currences of the red could be observed in the supplementary bows, but the red or reddish colour 
only could be detected, forming narrow bows within the primary; the secondary bow very 
distinct. 
May 1 11. Strong twilight (?) to NNW. 11" 6™,. Meteor to E., altitude 45°, moving towards SE. 
Thunder-storms to-day 13 miles off to SSW. 
May 4 12 59. A meteor moved up from about 45° above SE., to 65° above E. Crepuscular light throughout 
the night. 
May 15 19. Many varieties of cirro-strati, chiefly in woolly sheets ; a few sheets of mottled cirro-strati, lines 
of cirro-strati lying N. and S., like lines of very small cumulo-strati; zigzag lines to N. ; 
cumulo-strati to NW.; loose cumuli on Cheviot. 
July 31 1 50. Clouds moving up from §. and SE., very thick and black, the clouds have a variety of motions 
inter se. 2 0m, Thunder to SE. 2™, Rain®. 4™, Another peal to SE, Very little rain 
after 20™. 
2 15—20. Occasional peals from SE. 
22. A flash of lightning, thunder in 78. 
25. A fine streak to E., altitude 45°; thunder in 635. 
26. A fine streak to E., from altitude 20° to horizon, having the appearance of waves in a rope | 
shaken. ' 
27. A double flash to E., forming an arch from E by S. to E by N., altitude 15°. 
29. A very complex flash to E., altitude 6°, interval 125. 
30. Streak to E., altitude 6°. 
35. A large streak went parallel to the horizon to NE., and then bisected itself at right angles, stretch- 
ing over about 30° of horizon, interval 125., altitude 10°. 
38. A streak about 10° long inclined to the horizon at 80° to NE., interval 88, like an illuminated 
serpentine copper wire. 
40. About 20 flashes have been seen since 20™, the rolls have been almost uninterrupted, 
40. Flash to NNE., interval 105. 
41. Flash to NNE., interval 8:—105, 
48. Two flashes, one to NE by E., and the other to N., interval 22s. 
44, Flash to NNE., interval 138, altitude 5°. 4 
45. Three streaks pependicular to the horizon to N by E., interval 30s. | 
Flash to N by E., interval 335. he 
One to NE., altitude 15°, and another to N., interval 11s from NE.; the thunder continued — 
at intervals to NE. and N. ‘<a 
3.10. A flash to NE by N., altitude 10°, interval 145 ; this is the only flash seen since 2 45™, although — | 
the lightning was looked for, All the flashes or streaks had the same character, viz., like | 
the undulations of a slack rope. The thunder like the sound of a cart’s wheels moving over | 
very irregular pavement, with many variations of intensity. Thunder heard last about 3" 35™, |
