arly equal, distance 3", p. 156 deg.. A low
power suffices to show the three stars in 19, their magnitudes being six
and a half, seven and a half, and eight, distances 15", p. 312 deg., and
215", p. 358 deg.. Webb describes the two smaller stars as plum-colored.
Plum-colored suns!

At the opposite end of the constellation are two fine doubles, Sigma
1333, magnitudes six and a half and seven, distance 1.4", p. 39 deg.; and
38, magnitudes four and seven, distance 2.9", p. 235 deg..

Under the guidance of map No. 6 we turn to Leo, which contains one of
the leading gems among the double stars, gamma, whose components, of the
second and fourth magnitudes, are respectively yellow and green, the
green star, according to some observers, having a peculiar tinge of red.
Their distance apart is 3.7", p. 118 deg., and they are undoubtedly in
revolution about a common center, the probable period being about four
hundred years. The three-inch glass should separate them easily when the
air is steady, and a pleasing sight they are.

The star iota is a closer double, and also very pretty, magnitudes four
and eight, colors lemon and light blue, distance 2.17", p. 53 deg.. Other
doubles are tau, magnitudes five and seven, distance 95", p. 170 deg.; 88,
magnitudes seven and nine, distance 15", p. 320 deg.; 90, triple, magnitudes
six, seven and a half, and ten, distance, 3.5", p. 209 deg., and 59", p.
234 deg.; 54, magnitudes four and a half and seven, distance 6.2", p. 102 deg.;
and 49, magnitudes six and nine, distance 2.4", p. 158 deg..

Leo contains a remarkable variable star, R, deep red in color, and
varying in a space of a hundred and forty-four days from the fifth to
the tenth magnitude. It has also several nebulae, of which only one needs
special mention, No. 1861. This is spindle-shaped, and large telescopes
show that it consists of three nebulae. The observer with ordinary
instruments finds little to see and little to interest him in these
small, faint nebulae.

We may just glance at two double stars in the small constellation of
Sextans, situated under Leo. These are: 9, magnitudes seven and eight,
distance 53", p. 292 deg.; and 35, magnitudes six and seven, distance 6.9",
p. 240 deg..

Coma Berenices (map No. 6) includes several interesting objects. Let
us begin with the star 2, a double, of magnitudes six and seven and a
half, distance 3.6", p. 240 deg.. The color of the smaller star is lilac
