distinguish the nucleus from the tail at that point. The denseness of 
the nucleus was so great that Mr. C. has no doubt that it might have 
been visible upon the sun’s disk if it had passed between it and the ob- 
server. This dense appearance he considers due in part to the fact 
that the tail was foreshortened by projection, and so directed with ref- 
erence to the earth, that the nucleus must have been seen through a 
considerable mass of the matter of the tail. Notwithstanding the difh- 
culties resulting from the nearness of the comet to the sun shining in 
its strength, Mr. C. succeeded in remy with an desiroment of reflec- 
tion the following measurements, v

_ The first of these measures Mr. Bs iidons feliatite within 15"; 
and the other two may be taken as near approximations. Due allow- 
ance must of course be made for the motions of the two bodies during” 
the depot of observation. When the sun was in the plane of the me- | 
tidian, the angle made by the line joining the centres of the sun and 
sae with the lower vertical, on the eastern side, was about 73°.

10. Second Comet of 1843.—M. Victor Ve an astronomer at- 
tached to the Paris Observatory, discovered May 3, 1843, a telescopic 
comet on the limits of the constellations Cygnus and Pegasus. It is a 
feeble nebulosity, of an oval shape, and about 3’ diameter, with a sen- 
sible condensation of light towards the centre. It was seen by Sir J. 
South at ee on. the 10th of the same month,—Lond. Ath. 
May 13, 1843.

night, which was one of uncommon sereneness. The number of me-

number, visible after midnight, at she seasons,—or from twelve to 
an hour for an individual obsery
