east. If Nova Persei be now visible it will be seen quite 
near the horizon, together with Algol and Alpha Persei, 
and the Hyades also farther to the west, all of them near 
to setting. Over in the northeast almost exactly, Vega may 
be seen just rising, while Cassiopeia and Cepheus have 
reached their lowest culmination, one on each side of the 
meridian, thus fixing the limit of the region of stars that 
never set to the Manchester observer. 
While surveying this portion of the heavens the observer 
may, if he can crane his neck sufficiently, see a small group 
of third and fourth magnitude stars between L,eo and Ursa 
Major. This is the constellation Ursa Minor. Although 
so few are now visible yet it contains fifty-three stars, only 
one of which is of the third magnitude and five of the fourth. 
This is comparatively a modern constellation, having been 
formed by Hevelius out of the surplus stars between Leo 
and Ursa Major ungrouped by the ancients. 
Directly east of the Dipper and Ueo Minor can be seen, 
perhaps half way between the Dipper and Arcturus, a star 
of the third magnitude. This is Cor Caroli or Charles’ 
Heart, so named by Sir Charles Scarborough in memory of 
King Charles the First. It is the most prominent star in 
the constellation Canes Venatici, the grayhounds, or hunt¬ 
ing dogs. This also is a modern constellation, having been 
made by Hevelius out of the ungrouped stars between Bootes 
on the east, and Ursa Major on the west. These hounds 
are represented on the pictorial star maps in pusuit of the 
Great Bear which Bootes, the mighty hunter, is following 
around the pole, while he holds in his hand the leash by 
which they are fastened together. Their names are Asteri- 
on and Chara. 
South of Canes Venatici and on a line drawn fromRegu- 
lus to Arcturus and about two-thirds the way may be seen 
a beautiful cluster of small stars between the fourth and 
fifth magnitudes, their confused lustre somewhat resembl-
