gaze; but after it passed behind the dense cloud, and having waited a little I was 
about to start, it reappeared near the horizon. There were no stars visible by 
which I could fix its point of appearance, or its track; but its course seemed to 
me very nearly east—perhaps a little south of east. 1 
Eoyalton , New York, Lat. 43° 6', Lon. 78° 40'. Observed by Lewis Swift, who 
says that the meteor passed from W.N.W. to E.S.E. “ a little south of the zenith,” 1 2 
and that it was in sight probably about 1J minutes. 
Sag Harbor , New York, Nos. 106, 147, 153, 212, and 231. Communicated by 
Ephraim N. Byram, by whom also the measurements were made of positions 
estimated by the observer, John C. Smith. These estimates and measurements 
were kindly made at the request of the author, more than two months after the 
meteor appeared, and must of course be less reliable than if they had been made 
at the time. 
Saratoga, New York, Lat. 43° 6', Lon. 74°. Reported time 10 o’clock. 3 
Search (steamer), No. 3. Communicated by Capt. George G. Meade, Superin 
tendent of the U. S. Lake Survey, and Lieut. Orlando M. Poe, Engineer and 
Astronomer, from observations made by the latter. After remarking that he had 
a very distinct view of the meteor at times, though the sky was so much obscured 
by light clouds as to render it impossible to project its path upon the heavens by 
reference to the stars, Lieut. Poe says that when first seen in a direction between 
E. by S. and E.S.E., “ it appeared to be a brilliant ball, of one-half the moon’s 
diameter, and at an altitude of about 40°. The direction of its path was from 
N.W. to S.E., and extended through nearly 10° of arc. It brilliantly illuminated 
the clouds in its vicinity, and moved very slowly, occupying about 20 seconds of 
time in passing over the space estimated above. 4 5 It did not, while visible to me, 
break into fragments.” 
Seneca (barque), No. 11. Observed by Capt. Feinhagen of this vessel, off 
Barnegat light. Another account of this observation adds that the motion was 
“ tremulous,” and the duration about 30 seconds. Time 9h. 45m. 
Sneeden’s Landing , New York, Lat. 41° 3', Lon. 74°. Reported in the New 
York Evening Post to have passed almost vertically over this place.® 
Southampton , New York, Nos. 66, 70, and 149. Copied from a newspaper 
report, in which the observer, under the signature “ H,” says of the meteor, that, 
“ At about 9h. 50m. 6 o’clock it was seen about 25° high to shoot upwards, like a 
rocket, from the constellation Leo Major;” that it “passed near Corona Borealis, 
crossing the meridian a little south of the zeniththat it separated when near the 
1 According to the calculated path, the course of the meteor, when it passed the meridian of Romeo, 
was S. 78° 12' E. 
3 According to the calculated path, the meteor passed about 20 miles south of the zenith. 
3 Calculated time of meridian passage 9h. 47m. 49 sec. 
4 According to the calculated path, the apparent are described in 20 seconds was over 30°, and the 
meteor, at the end of that interval, was within 10° of the eastern horizon. 
5 According to the calculated path, the meteor passed 9 or 10 miles N.E. from the zenith. 
6 Calculated time of meridian passage at Southampton, 9h. 54m. 29 sec.
