A CATALOGUE OF OBSERVATIONS OF LUMINOUS METEORS, 79 
‘and explosion twenty miles above it, upon the meridian of Land’s End. The 
flight of 360 miles appears to have occupied seven or eight seconds of time. 
Meteor, 1861, November 15th, 10" 14™ p.m. 
The meteor described by Mr. Nash at Greenwich, and Mr. Herschel at 
Shooter’s Hill, although identical, do not admit of useful comparison with one 
another, nor with that observed by Mr. Greg at Styall, near Manchester,—the 
base-line in the former case being too small for such a purpose, and the third 
meteor being apparently distinct from the former two. 
Meteor, 1861, November 19th, 9 38™ 30s p.m. 
_ The Ipswich and Norwich accounts place the audible explosion of this bril- 
liant meteor at no great height between the two towns ; thirty miles of height 
must be allowed to it for the altitude as seen from Exeter, although such a 
height is at variance with the view obtained from Greenwich and North Fore- 
land. It is not impossible that explosion, audible at Norwich and Ipswich, 
and perhaps also at North Foreland, may have depressed the last portion of 
the flight, for this was hidden from view at Exeter. The near verticality 
at North Foreland, the passage over the moon (whose altitude was 38° E. by 
8.) in the eastern parts of Kent, and the low southern position of the nucleus 
as first perceived by Messrs. Hill at Woodford, Mitchell and Harmer at Tun- 
bridge, and James Rock, jun. at Guestling, show this meteor to have taken a 
nearly meridian and nearly horizontal course. A flight of 260 miles in 10 
or 12 seconds, from fifty-five miles above Paris to thirty miles above Beccles 
(between Suffolk and Norfolk), is found to satisfy the whole of the accounts 
with considerable accuracy. 
Meteors, 1861, November 24th, 8 0™ p.m, 
The resemblance of these meteors is casual,—the lines of sight of com- 
mencement lying widely upon opposite sides of the base-line between the 
stations, while those of termination approach no nearer than twenty-six miles 
upon the southern side of the base-line. 
Meteors, 1861, December Ist, 9" 15" p.x. 
The resemblance of these meteors is not borne out by the uranographical 
positions assigned to them at the two distant stations,—the point of com- 
mencement having little or no parallax with considerable deviation of the 
lines of sight, while the lines of sight of termination lie upon opposite sides 
of the base-line. 
Meteor, 1861, December 8th, 8" 16™ p.m. 
At Dungannon in Ireland this meteor appeared to fall vertically, while at 
Wakefield (Yorkshire) it passed overhead. The observation of Dr. Walker at 
Birkenhead (Seacombe), assigns Strangford, on the Irish coast, as the spot 
between these two towns where the body would have struck the earth. By 
Mr. Redford’s account, from Silloth near Carlisle, the height at disappearance 
is found to be fifty miles above the sea, halfway from Lancaster to the Isle of 
Man; the height above Wakefield eighty-five miles, and at Hull 110 to 115 
miles. Modified by the remaining accounts, a course of 160 miles from 110 
miles above Hull to forty-five miles above the Irish Sea, twenty miles E. of 
| Douglas Town, performed in six or eight seconds of time, appears to be a near 
approximation to the truth. It is possible that an explosion loudly heard at 
Lancaster and Southport, but not heard at Douglas, may have caused the 
deflection by which the meteor in the latter portion of its flight appeared sta-
