96 brilliancy on the 20th. Full moonlight prevented any further records of the vanishing star, but taking advantage of a very fine interval during the totality of the lunar eclipse of June 1st, its invisibility was satisfactorily established; and though sought for on every suitable opportunity throughout the following five months, it has not since re-appeared.

The light comparisons actually made were as follows:

Of the other new variable, situated in the constellation Sagittarius, little more can be said than that it was first seen on July 19th 1883, as a somewhat ruddy star of the 8½ magnitude; and that from then until the present time it has slowly and steadily diminished to the 12th magnitude, or one twenty-fifth of its greatest recorded intensity of light. Dates of its actual invisibility in previous years cannot be furnished as in the case of U Scorpii, but if visible at all it was most certainly less than 11½ magnitude on August 30th 1859; on July 22nd, and on August 7th 1860.

The approximate positions of the two new stars, reduced to 1860, are:
