He gave the approximate period of revolution of some of these: Castor, 342 years; delta Serpentis, 375 years; gamma Leonis, 1,200 years; epsilon Bootis, 1,681 years. Twenty years later Sir John Herschel and Sir James South, after re-examination of these stars, confirmed and extended the results, one pair of Coronae having in the interval completed more than a whole revolution.

We were now in full view of Spencer's gulf, but as yet could observe no signs of the WATERWITCH, which was to meet us at the head of the gulf with additional stores. At night I observed the latitude by altitude of a Bootis to be 32 degrees 41 minutes 28 seconds S. July 2.

In the selection of i Bootis as a test, Arago has taken the precaution of giving its corresponding denomination in other catalogues, and Bailey appends the following note, No. 2062, to 44 Bootis.

Approximate periods were fixed for many of the revolving suns for Castor 342 years; for Gamma Leonis, 1200, Delta Serpentis, 375, Eta Bootis, 1681 years; Eta Lyræ was noted as a "double-double-star," a change of relative situation having been detected in each of the two pairs composing the group; and the occultation was described of one star by another in the course of their mutual revolutions, as exemplified in 1795 by the rapidly circulating system of Zeta Herculis.

Its distance decreased about 1" between 1881 and 1891. It was still decreasing in 1899, when it had become 2.5". The orbital swing is also very apparent in the change of the position angle. The telescopic gem of Boötes, and one of "the flowers of the sky," is epsilon, also known as Mirac. When well seen, as we shall see it to-night, epsilon Boötis is superb.

Indeed ê Coronæ is a sort of miniature of i Bootis, which may itself be considered as a miniature of a Gem.
