tion Draco. D’Arrest has calculated the following slosnenia viz.

BP Bo Comet.—On the 29th of August, 1850, Mr. Geo. P. Bond, 
of the Cambridge Observatory, discovered a faint ‘telescopic comet in 
the constellation Camelopardus. It was subsequently discovered by 
four independent observers. The following elements of its orbit by Mr. 
T. H. Safford, Jr., (Astr. Jour., No. 16,) are based on the Cambridge 
observations of Aug. 29, Sept. 3 and Sept. 8

6. Shooting ee of pie. 10, 1850.—Throughout the evening of 
Thursday, Aug. 8, 1850, the sky was quite hazy, and at dawn of the 
next day was L. entirely overcast. The night of Friday, the 9th, 
was clear, and observations fan the expected meteors wes made by 
Messrs. J. L. Blodget, M.C. Weld and myself. Dur 
twenty minutes we noted four hundred and fifty-one different shooting 
stars as follows, viz. 
N. E. s. N.W. 
from Oh. 40m. to. lam. 15 28 12 = 55 
ge van 40 107 69 = 216 
ee 3 43 78 59 = 180 
Of these many were very brilliant, and the majority moved in aths 
which, traced back, would intersect in the vicinity of the constellation 
erseus. 
dy mee of Saturday, the 10th, was also clear. From 10" to 124 
s. Bradley, Blodget and Root observed three hundred and 
po me diferent shooting se as follows, viz. 
8. Ww. 
10h.—11h. 48 80 AG =e 173 
1th.—12h. 55 36. ORs 139 
From midnight to 3 a.m., Messrs. Wm. Hillhouse and H. W. Brins- 
made observed three hundred and fifty-one different shooting stars, al- 
though many were lost by an intermission of about an hour on the part 
of one of the observers. 
The foregoing facts show oe the usual meteoric period of Ase aa 
was fully sustained the presen 
t may be worthy of owe that a slight display of the 
Borealis was seen here during most of the night of the 9th, ang 
on the night of the 10th. E, C. Herrick.
