The star appears to be at about 10'."5 at minimum, the change in brightness lasts six or seven hours and the minima follow each other at intervals of about 21.8 hours. It is probably of the Algol type. /3 Lyrae.--In A. N. 4005 Mr. S. Beliawsky, a student in the University of St. Petersburg, gives a light-curve of this variable star based upon his reduction The Light Curve Of p Lyr.e. of the observations made by Professor Glasenapp during the ten i ears 18921902. The curve is in general like those which have been previously published but presents some minor differences. Missinjf Stars.--Mr. J. Guillaume states, in.4. N. 4005, that the star BD. 4-17, 344 9'."5, R. A. (1855)= 2" 12m 290; Decl. + 17 50'.8, was missing from the skv on Feb. 4, 6, 8 and 9, 1905. Mr. Ludendorff also, in A. N. 4006, calls attention to the star BD. + 37, 855, 9ra.5 R. A. (1855) 3" 51m 0."49; Decl. + 37 35'.5, which he finds to be missing from photographs taken Nov. 26, 1896, and Oct. 16, 1899. Variable Star Y Aurigae.--The Monthly Xotices of the Royal Astronomical Society, England, for January 1905, contains an excellent paper by Mr. A. Stanley Williams on the Variable Star Y Aurigae, in which he gives a determination ot the elements of the light variation of the star from a long series of observations by himself, extending from Feb. 6, 1901 to Apr. 20, 1904. According to the light-curve the star wanes steadily for about two days and a quarter, is almost at a stand still at minimum for a dav, then rises to maximum in a little over half a day, remaining at maximum for only a very small fraction of a day. The total period of the variation is 3.8590 days or 3d 20" 36" ' 58b, t...
