plates, at the close of the volume, full representations of both 
the greater and the lesser Nubecula, as seen by the naked eye. 
The telescope, however, makes amends for any disappointment 
which may have been felt on first meeting with these celebrated 
members of the southern hemisphere. ‘This noble instrament 
reveals to us, instead of faint “patches” of light, a wonderful 
congeries of nebulew, for the most part scattered here and there 
without any apparent order, but still presenting, among its sub- 
inate members, marks of symmetry and organization. A 
large sheet among the plates at the end of the volume, affords us 
the gratifying spectacle of both the nubecule, as seen in the 
twenty-feet reflector ; and fine drawings of the more curious sub- 
ordinate groups, are also given among the engravings of remark- 
able nebule. The Nubecula Major is situated at an average dis- 
to the square degree, which by far exceeds any thing to be met 
vith in any other region of the heavens. Even the most crowd- 
ed parts of the stratum of Virgo, in the wing of that constellation, 
or in Coma Berenices, offer nothing approaching to it. It is evi- 
dent from this, and from the intermixture of stars and unresolva- 
ble nebulosity which probably might be resolved with a higher 
optical power, that the nubecule are to be regarded as systems 
sui generis, and which have nothing analogous in our hemis- 
phere.” p, 147. : 3 7
