MARS

Will present nothing particularly new. His retrograde motion still

continuing, he will rise earlier each evening, and, of course, set

earlier the following morning. Thus, on the 1st, he rises at 4:51 p. m.;

on the 15th, at 3:35 p. m.; and on the 29th, at 2:23 p. m. He sets on the

mornings immediately following these dates at 7:29, 6:23 and 5:15; or, on

the first date about twenty minutes after, and on the latter date about

one hour and twenty minutes before sunrise; during the month taking his

place as an evening star. His motion amounts to 9° 7′ 11″ of arc, and as

he is going farther from the earth, his diameter grows smaller, being

15″ on the first, and only 13.2″ on the last of the month. On the 10th,

at 4:40 a. m., he is 9° 43′ north of the moon, and a little east of the

nebula _Præsepe_ in _Cancer_.
