broken physical nature, yet this would hardly belong to our department. 
We shall be pleased if we succeed in calling particular attention to a 
work written in a fine philosophical spirit, with a true English practical- 
ity, and in a style excellent for its plainness and lucidity. 
We may add that the “ getting up” of these volumes is quite com- 
plete. Printed ina large clear type, and on excellent paper, it is indeed, 
a delight merely to read such writings. ere are, moreover, constant 
wood-cuts intercalated in the text, which, for cleanness, are in keeping 
with the rest of the “work” of these volumes ; and, finally, what we 
always like to see, there is a very complete and convenient index at 
the end. W. I. B.

1, New Comet, IV of 1853, (Astr. Journal, 64.)—On the night of 
Sept. 11, 1853, Mr. C. Bruuns, in Berlin, detected near the forward paw 
of the Great Bear,a “ large faint nebulous comet, resembling a star- 
cluster.” Its position Sept. 11, 134 12™ 153-3 was RB. A. 126° 59’ 11-5, 
and Decl. + 44° 51’ 33-6. Its position Sept. 15, 128 18™ 538-8 was 
132° 22' 8-9 in R. A., and + 42° 29' 545 in Decl. Up to Sept. 
17, no indications of a tail were visible, and the nucleus continued to 
present the appearance of an unresolved nebula, with numerous points 
of light. From the observations of Sept. 11, 13, 15, Mr. Bruns had 
deduced the elements given below, which however, owing to the disad- 
vantageous position of the comet, he considers as being only a tolerable 
approximation.
