2Q% Dr. Herschel’s Astronomical Observations 
owe their origin to some former common stock of nebulous 
matter. 
To refer astronomers to the heavens for an inspection of 
these and the following nebulae, would be to propose a repeti- 
tion of more than eleven hundred sweeps to them, but those 
who wish to have some idea of the nebulous arrangements 
may consult Mr. Bode's excellent Atlas Coelestis. A succes- 
sion of places where the nebulae of my catalogues are uncom- 
monly crowded, will there be seen beginning over the tail of 
Hydra and proceeding to the southern wing, the body and 
the northern wing of Virgo, Piate 14. Then to Coma Bere- 
nices, Canes venatici, and the preceding arm of Bootes, 
Plate 7. A different branch goes from Coma Berenices to 
the hind legs of Ursa major. Another branch passes from 
the wing of Virgo to the tail and body of Leo, Plate 8. 
It. will not be necessary to point out many other smaller 
collections which may be found in several plates of the same 
Atlas. 
On the other hand, a very different aspect of the heavens 
will be perceived when we examine the following constella- 
tions. Beginning from the head of Capricorn, Plate 16, thence 
proceeding to Antinous, to the tail of Aquila, Plate 9, to Ramus 
Cerberus, and the body of Hercules, Plate 8, to Quadrans 
Muralis, Plate 7, and to the head of Draco, Plate 3. We may. 
also examine the constellations of Auriga, Lynx, and Came-- 
lopardalus, Piate 5. 
In this second review, it will be found that here the absence 
of nebulae is as remarkable, as the great multitude of them ini 
the first mentioned series of constellations*
