Mercury rises nearly at the same time as the sun on the first day, and gradually earlier each day, the interval increasing to an hour and a quarter before the sun on the 30th.

Venus is too close to the sun to be well observed, setting on the Ist about forty minutes after the sun, the interval increasing to one hour on the last day.

Mars may be observed half-an-hour after midnight at the beginning of the month. He rises about forty-five minutes before midnight on the last day.

Jupiter rises about an hour and a quarter after sunset at the beginning of the month, the interval decreasing. Towards the end of the month he rises before sunset. He is at opposition to the sun at midnight on the 19th.

Saturn rises rather more than an hour after midnight on the 1st, the interval decreasing. He rises three-quarters of an hour before midnight on the last day, and is at quadrature with the sun on the roth.

The 24 sketches of Mars, made in 1862 and 1864 by Mr. Banks and Mr. Green, and published in Vol. III. of the Astronomical Register, p. 71; 4 sketches by Mr. Dawes, re-published in the same volume, p. 221, and the 16 sketches by Mr. Webb, published in Vol. IV. of the Intellectual Observer, p. 182, are arranged in the following list according to the longitudes of their central meridians :

* The numbers of Mr. Banks' and Mr. Green's sketches made in 1864 are distinguished by an asterisk from those made in 1862.

The times of Mr. Webb's sketches, No. 3 and 5, which are not given in his paper in the Intellectual Observer, have been kindly supplied by him, as their uncertainty is really not greater than that of the others.

Another list of sketches made in 1862 and 64, of which the present one may be considered a supplement, will be found in the Monthly Notices for April, page 305-307.

were balloted for and duly elected Fellows of the Society.

The President: One of the names for suspension this evening is that of Mr. Lambert, the gentleman from whom the Society has received £500, part of a sum left by his father to be distributed chiefly for scientific purposes, and I am sure you will be happy to record your votes in his favour, as an expression of your acknowledgment of his selection of this Society as one of the recipients of his father's gift.

VOL. XV.

The President: I regret that it is my duty to state that the two Fellows whose names have been suspended in the meetingroom, in accordance with the Bye-laws, are to be expelled from the Society; their names are: Mr. J. Garbut and the Rev. T. Tordiffe. They are each in arrear with their subscriptions eight guineas. I therefore pronounce them to be expelled from the Society for non-payment of their subscriptions.

The President: Before proceeding to the papers to be read, I will mention that Mr. Stone, Her Majesty's astronomer at the Cape of Good Hope, has presented to the Society a volume of tables for facilitating the computation of star constants, which he has just published. In a private letter which I have received from him, he requests me to state that he will be happy to receive applications for copies of these tables from any Fellow of the Society to whom they would be of real use. As we shall

have to proceed at an early hour to the special meeting we have only a short time now for the ordinary business of the Society. There are three gentlemen who have viva voce communications to make to us. I will call on Mr. Marth first.

Mr. Marth: I will occupy only a few minutes of your time in
