Comets and Meteors: Their phenomena in all ages; their mutual relations; and the theory of their origin.

Comets; Meteors
The fact that all great displays of the November meteors have taken
place at intervals of 33 or 34 years, or some multiple of that period,
had led to a general expectation of a brilliant shower in 1866. In this
country, however, the public curiosity was much disappointed.[22] The
numbers seen were greater than on ordinary nights, but not such as would
have attracted any special attention. The greatest number recorded at
any one station was seen at New Haven by Professor Newton. On the night
of the 12th 694 were counted in five hours and twenty minutes, and on
the following night, 881 in five hours. A more brilliant display was,
however, witnessed in Europe. Meteors began to appear in unusual
frequency about 11 o'clock on the night of the 13th, and their numbers
continued to increase with great rapidity for more than two hours; the
maximum being reached a little after 1 o'clock. A writer in Edinburgh,
Scotland, thus describes the phenomenon as observed at that
city:--"Standing on the Calton Hill, and looking westward,--with the
observatory shutting out the lights of Princes Street,--it was easy for
the eye to delude the imagination into fancying some distant enemy
bombarding Edinburgh Castle from long range; and the occasional
cessation of the shower for a few seconds, only to break out again with
more numerous and more brilliant drops of fire, served to countenance
this fancy. Again, turning eastward, it was possible now and then to
catch broken glimpses of the train of one of the meteors through the
grim dark pillars of that ruin of most successful manufacture, the
National Monument; and in fact from no point in or out of the city was
it possible to watch the strange rain of stars, pervading as it did all
points of the heavens, without pleased interest and a kindling of the
imagination, and often a touch of deeper feeling that bordered on awe."
At London about 1 o'clock a single observer counted 200 in two minutes.
The whole number seen at Greenwich was 8485. The shower was also
observed in different countries on the continent.
[22] The first indication of the approaching shower was the appearance
of meteors in unusual numbers at Malta, on the 13th of November,
1864. In 1865, as observed at Greenwich and other stations, they
were still more numerous.
In 1867 the display was generally observed throughout the United States.
From the able and interesting reports of Commodore Sands and Professors
Newcomb, Harkness, and Eastman, we derive the following facts in regard
to the shower as seen at Washington, D. C.:
Commencement 1_h._ 0_m._ A.M. Nov. 14.
Maximum 4 20 " "
End 5 0 " "
Number of meteors per hour at maximum 3000
Mean height on first appearance 75 miles.
" " on disappearance 55 "
Position of radiant, R. A. 151°, Decl. 22-1/2°.
