The components are nearly equal and rather more than 5" apart (see Plate 3).

Both are white according to the best observers, but the smaller is thought by some to be slightly greenish.
Pollux is a coarse but fine triple star (in large instruments multiple).
The components orange, grey, and lilac.
There are many other fine objects in Gemini, but we pass to Cancer.
The fine cluster Praesepe in Cancer may easily be found as it is distinctly visible to the naked eye in the position shown in Plate 1, Map I.In the telescope it is seen as shown in Plate 3.
The star [iota] Cancri is a wide double, the colours orange and blue.
Procyon, the first-magnitude star between Praesepe and Sirius, is finely coloured--yellow with a distant orange companion, which appears to be variable.
Below the Twins, almost in a line with them, is the star [alpha] Hydrae, called Al Fard, or "the Solitary One." It is a 2nd magnitude variable.

I mention it, however, not on its own account, but as a guide to the fine double [epsilon] Hydrae.

This star is the middle one of a group of three, lying between Pollux and Al Fard rather nearer the latter.

The components of [epsilon] Hydrae are separated by about 3-1/2" (see Plate 3).
