Piazzi Smyth, whose crater is in the neighbourhood, speaks of it in his "Astronomer's Experiment," as the "Piton" crest of the oldest of the triple heads of one central peak or cone of eruption. Rambleta. On the moon it is in a line with, but some distance from, the Teneriffe Mountains Chajona, Rambleta, Alta-Vista, etc. It is a little S. W. of Piazzi Smyth, which is between it and Pico, the latter being well known in the nomenclature of the Island of Teneriffe as the "Peak." See map and sections in "An Astronomical Experiment."

The major and minor semi-axes a and b of the apparent orbits and the angle of position p°. of the major axes are the following I. 21.14 8:46 March ΙΟΟΙ 15:18 6'08 3468 13.88 46.38 18:57 In these apparent orbits the satellites move so that the angles of position decrease, or the direction of their motion is that of the (ordinary) hands of a watch. For the purpose of knowing whereabout the satellites are to be found, it will, perhaps, be sufficient to learn the approximate times of their being at the ends of the major axis or at their greatest northern and southern elongations N. and S. In the cases of Titania and Oberon the approximate hours of their being at the ends of the minor axis, or at their superior and inferior conjunctions, "sup." and "inf." are added.

The General Meeting, February 9th, 1877. William Huggins, Esq., D.C.L., LL.D., F.R.S., &c., President, in the Chair. Secretaries-Mr. Dunkin and Mr. Ranyard. The minutes of the preceding General Meeting were read and confirmed. John Sidney White, Esq., 13, Bolton Gardens, South A. Mason Worthington, Esq., of Sandiway House, George Francis Hardy, of Rothbury House, Stroud Green, were duly elected Fellows of the Society. The annual report of the Society shows that two legacies have been received in the course of the past year; the one a sum of £2,000 Consols, under the will of the late Mr. Carrington, and the other a sum of £200 under the will of the late Mr. T. C. Janson. Twenty-nine new Fellows have been elected in the course of the past year, and after making deductions for deaths, resignations, and expulsions, the number of Fellows has increased by 12 in the course of the year. Amongst the obituary notices is one of Miss Anne Sheepshanks, a sister of the Rev. R. Sheepshanks, who was for many years a secretary of the Society. Miss Sheepshanks founded during her lifetime, in memory of her brother, the well-known astronomical scholarship which bears his name in connection with Trinity College, Cambridge. She also handsomely endowed the Cambridge Observatory, and at her death bequeathed to the Astronomical Society many valuable books from her brother's library. The Society's library has also been enriched in the course of VOL. XV. |
