MERCURY

Will be evening star during the entire month. But it matters little, so

far as seeing it with the naked eye is concerned, until near the close

of the month, whether it be morning or evening star. On the 1st it sets

at 4:35 p. m., and is then too near the sun to be seen. On the 30th it

sets at 6 p. m., a few minutes before the moon, and about 5½° south of

the latter body. On the 31st it sets at 6:03 in the evening, about one

and one-third hours later than the sun, and 1½° north of where the sun

disappears. On both these evenings, and for several days both before and

after these times, this planet is visible to the ordinary eye, and by its

bright white light is readily recognized. Although visible several times

each year, it is a remarkable fact that it has been seen by comparatively

few persons. In the higher latitudes it is much more difficult to see

than in the lower, and the atmosphere of some parts of Europe is very

unfavorable for its observation.
