I had an opportunity of developing my ideas, that have already been published on the subject, more fully. The doctrine has, as I apprehended it would, excited the attention of philosophers throughout Europe. Two journals in the German language came into the Royal Institution whilst I was there from Saxony, both of which were about half filled with translations from the papers I have written on this subject and comments upon them. Dr. Ainslie was occasionally one of my audience, and his sons constantly. He came up at the concluding lecture, expressed his high satisfaction, and he believed it was the same sentiment with all or most of the audience. I saw my successor, William Allen, fairly launched. He gave his first lecture on Tuesday, preceding my conclusion. I was an _auditor_ in this case--the first time--and had an opportunity of surveying the audience. Amongst others of distinction the Bishop of Durham was present. In lecturing on optics I got six ribbands--blue, pink, lilac, red, green, and brown--which matched very well, and told the various audience so. I do not know whether they generally believed me to be serious, but one gentlemen came up immediately after and told me he perfectly agreed with me. He had not remarked the difference by candle light. Throughout the year 1803 scarcely a trace of Count Rumford’s name can be found in the records of the Institution. On January 24, when writing from Munich to the clerk, Mr. Savage, about his house in Brompton Row, he only begs his compliments to Dr. Young and to Mr. Davy, and on November 11, the clerk having asked him about an account relating to the Institution, he wrote from Paris: I assure you that I have not the smallest recollection of having received from Mr. Hunter, the solicitor of the Institution, the account you mention in your letter of the 7th ult.; and had I in fact received it, I should most undoubtedly have laid it before the managers of the Institution. I can imagine no reason which could have induced me to keep it back; and, as all the affairs of the Institution in my hands were kept with the utmost care and regularity, as you can testify, it is not likely that I should have mislaid and forgotten it. This is all I can say on the subject, and I hope and trust that this declaration will be satisfactory to the managers of the Royal Institution and to Mr. Hunter. I expect to be in England in the course of the winter.
