Sir Joseph's maxim, which I hope will be adopted by all the members, is--"let it be given to the most worthy." I have no doubt that Mr.---- would fill the situation with credit, and that he is a very worthy man; but, from all that I can learn, his claims are much inferior to those of W----. We want not merely a civil, gentlemanlike, honest man, but a man a little accustomed to calculation, to astronomical observation, and to experiment. I am in a delightful country here--the Valley of the Tyne--enjoying a few days' leisure after a rather hard chemical campaign, and preparing health and spirits for another in Ireland, where I am going next week. I hope to be in London by the first week in December. I intend next summer to go into Cornwall--God willing; and I will not go through without seeing you, and telling you that, under all circumstances, I shall always think of you with the warmest esteem, and shall always be Your sincere friend, H. DAVY. In the following year, Davy was again solicited by the Dublin Society to deliver lectures in their laboratory; and at a meeting of the members on the 13th of June 1811, a series of resolutions were passed, by which he was empowered to procure copies of many of the geological sketches referred to in a course of lectures he had delivered on Geology at the Royal Institution; and also to superintend the construction of a large Voltaic battery, for the illustration of the proposed lectures. In compliance with this request, Davy delivered two distinct courses; one on the Elements of Chemical Philosophy, the other on Geology, for which he received the unanimous thanks of the Society, and as a more substantial testimony of their gratitude, the sum[97] of seven hundred and fifty pounds; the receipt of which Davy acknowledged by the following letter. [97] These Courses were more numerously attended than those in 1810, there having been issued about five hundred and twenty-five tickets; the proceeds of which were 1101_l._ 2_s._ TO B. MAC CARTHY, ESQ. ASSISTANT SECRETARY TO THE DUBLIN SOCIETY. Dublin, December 9, 1811. SIR, I have received your letter, inclosing a draught for seven hundred and fifty pounds Irish. I am very much gratified by the thanks of the Dublin Society, for the courses of lectures which I had the honour of delivering in their laboratory; and I am proud of their opinion, that they will be useful to the Irish public. The attention, candour, and indulgence with which they were received by the audience, I shall remember with the warmest feelings of gratitude as long as I live. I have the honour to be, Sir, with much esteem, your obliged and obedient servant, H. DAVY.
