e smaller one even with that aperture.

Other objects in Orion, to be found with the aid of our map, are: Sigma
627, a double star, magnitude six and a half and seven, distance 21", p.
260 deg.; Omicron Sigma 98, otherwise named iota Orionis, double, magnitude
six and seven, distance 1", p. 180 deg., requires five-inch glass; Sigma
652, double, magnitudes six and a half and eight, distance 1.7", p.
184 deg.; rho, double, magnitudes five and eight and a half, the latter
blue, distance 7", p. 62 deg., may be tried with a three-inch; tau, triple
star, magnitudes four, ten and a half, and eleven, distances 36", p.
249 deg., and 36", p. 60 deg.. Burnham discovered that the ten-and-a-half
magnitude star is again double, distance 4", p. 50 deg.. There is not much
satisfaction in attempting tau Orionis with telescopes of ordinary
apertures; Sigma 629 otherwise _m_ Orionis, double, magnitudes five and
a half (greenish) and seven, distance 31.7", p. 28 deg., a pretty object;
Sigma 728, otherwise A 32, double, magnitudes five and seven, distance,
0.5" or less, p. 206 deg., a rapid binary,[2] which is at present too close
for ordinary telescopes, although it was once within their reach; Sigma
729, double, magnitudes six and eight, distance 2", p. 26 deg., the smaller
star pale blue--try it with a four-inch, but five-inch is better; Sigma
816, double, magnitudes six and half and eight and a half, distance 4",
p. 289 deg.; psi 2, double, magnitudes five and a half and eleven, distance
3", or a little less, p. 322 deg.; 905, star cluster, contains about twenty
stars from the eighth to the eleventh magnitude; 1267, nebula, faint,
containing a triple star of the eighth magnitude, two of whose
components are 51" apart, while the third is only 1.7" from its
companion, p. 85 deg.; 1376, star cluster, small and crowded; 1361, star
cluster, triangular shape, containing thirty stars, seventh to tenth
magnitudes, one of which is a double, distance 2.4".

[2] The term "binary" is used to describe double stars which are in
motion about their common center of gravity.

Let us now leave the inviting star-fields of Orion and take a glance at
the little constellation of Lepus, crouching at the feet of the mythical
giant. We may begin with a new kind of object, the celebrated red
variable R Leporis (map No. 1). This star varies from the sixth or
seventh magnitude to magnitude eight and a half in a period of four
hundred and twenty-four days. Hind's
