$2.00, This is the 19th issue of this valuable publication replete with so much information that we may call it a real "multum in pardo." The reader who wishes to know something about the heavens will find here the exact time of sunrise and sunset, the. moon's phases, occulations of stars, eclipses, and 12 neat little charts, one for each month, showing the constellations visible on the horizon at 8,30 p.m.
brief notes, we are told that the side real day is shorter than the mean day, and that the most fav-curable time for observing _the vi of Saturn will be from Feb-to April, and again after August.
The special articles—though we confess they are a little abstruse for us—deal with the Mount Wilson telescope of 100 inches, donated by Mr. Hooker. This powerful instrwrent is most helpful for decomposing binary stars, such as Capella (the goat-star) and others. The article on new; stars, which suddenly blaze up in the heavens, is of absorbing interest. The theory that they encounter extinct worlds, or that the high pressure of their gaseous clements causes an internal explosion. is now discarded, and it is admitted that their meeting with tiny particles of cosmic matter explains sufficiently the phenomenon. The dark voids observed in the Milky Way, and generally known as "coalsacks," are filled with minute cosmic dust, and a body passing through it produces such friction that the star blazes up all of a sudden, and then gradually falls back into the nebular state.
