. On thes Spectrum of Coggia’s Comet; by Dr. Huce ns. —The 
hew waa noticed in this communication was 1 Bid the bands of the 
omet were so far shifted as to ee ee there really 
was carbon in the comet—that tbe relative motion of the approach 
of the comet to the earth was fonvate miles per second. The 
comet really, however, approached the earth at the rate of twenty- 
it w as therefore uncertain whether the 
motion of matter within the comet. The brighter portion of the 
head of the comet was due evidently to a larger proportion of the - 
matter giving a continuous spectrum. It seeme probable, there- 
fore’ to the “autnor that the nucleus was solid, heated by the 
sun and throwing ont matter which formed the coma and tail; and 
part of this was in a gaseous form, giving the spectra of bright 
ilnes, The other portion existed probably in small incandescent

e-fifth of the whole light was reflected solar light.—Proe. Bri it.
