“June 13th, 1811. _Resolved_--That a letter be written to Mr. Professor Davy requesting him to favour the Dublin Society and the Irish public with a further communication of the recent discoveries in chemical philosophy, and to deliver a course of lectures in their laboratory for that purpose, in the months of November and December next; and requesting that he will also repeat to them, at the same time, the course of lectures in geological science which he has read this year to the Royal Institution; and that he will be so good as to procure for the Society copies of as many of the geological sketches referred to in that course as he may think necessary for the elucidation of the subject; and further requesting him to superintend the construction of a voltaic battery of large plates, for the use of the Society, to be transmitted to them in time for these lectures.” We next read: “December 5th, 1811. _Resolved unanimously_--That the thanks of the Society be communicated to Mr. Davy, for the two excellent courses of lectures in chemical and geological science which, at their request, he has delivered in their laboratory, full of valuable information; and which have not merely continued, but materially increased, the spirit of philosophical research in Ireland. “_Resolved unanimously_--That Mr. Davy be requested to accept the sum of £750 as a remuneration on the part of the Society.” On the occasion of his second visit Trinity College, Dublin, conferred on him the degree of LL.D. It was the only mark of distinction he ever received from any University. Before he gave his lectures he visited Edgeworthstown, as we learn in a letter from Maria to Miss Ruxton: “Davy spent a day here last week, and was as usual full of entertainment and information of various kinds. He has gone to Connemara, I believe, to fish, for he is a little mad about fishing; and very ungrateful it is of me to say so, for he sent to us from Boyle the finest trout! and a trout of Davy’s catching is, I presume, worth ten trouts caught by vulgar mortals.” To his mother he writes: “Ballina, Ireland, _October 24th_. “MY DEAR MOTHER,--I am safe and well, in a remote and beautiful part of Ireland, where I have been making an excursion with two of my friends. I shall return to Dublin in two or three days, and shall be very glad to hear from you or my sisters there. I hope you are all well and happy. “I heard from John a few days ago; he was quite well and in good spirits.
