Went on Friday to Battersea to hear Robert Eden deliver a lecture in the school-room--one of a course he is delivering upon anatomy, or rather upon different parts of the human body--and demonstrating the utility of cleanliness, the danger of drunkenness, and mixing precept with information for the benefit of as mixed an audience as ever was assembled, but who seemed much interested and very attentive. There were many of the gentry of Battersea, male and female, the tradespeople, workmen, the boys of the school, and a rough, ragged set of urchins, labourers on the railroad--in all about 300 people. The lecture, which was upon the arm, was very fluently given; the lecturer is not sufficiently master of his subject to make his explanations very lucid and perfectly intelligible, but he conveys good general notions, and introduces such a mixture of anecdote and illustration as makes it sufficiently entertaining. The undertaking is highly laudable; it is carried on with great zeal and spirit, very considerable ability, and, as far as it has gone, with complete success. Dined yesterday at the Hollands': Normanby, Melbourne, and Luttrell; pretty good talk. Melbourne, rather paradoxical, asserted that 'men with quick feelings were always the worst men; that he could not work out the proposition metaphysically then, but that he should do.' It was the assertion of Brougham's having quick feelings which elicited the saying, though certainly Brougham is not the _worst_ of men: far from it, nor did he mean to say so. Brougham denies this pamphlet, and says he cannot be the author for this reason: the pamphlet reasserts something about Melbourne which he had asserted in one of his articles in the 'Edinburgh Review.' Melbourne, when he read that article, wrote to Brougham, and told him that as he was sure he did not wish to misrepresent him, he informed him that he had never entertained the opinions nor given the vote there ascribed to him. Brougham replied, admitting his error, and promising to correct it, offering to do so at Melbourne's option in another number of the 'Edinburgh Review,' or _in some other work_ (I forget what). Melbourne wrote back, in rather a jocular strain, that he thought it would be preferable to have the correction in the same publication as the statement, to which Brougham sent a good-humoured answer, and there it ended. After this, he says that he could not by possibility repeat the very same thing in another work that he had already engaged to recall, and this is certainly strong. At the same time there are things in it which no other man could have written. Just before it came out he was preparing something for the printer, for he came into my room with a parcel of proof-sheets in his hand, which I fancied were for me to frank to Macvey Napier, and I said so; when he replied, 'Oh no, they are going to the printer here.' It is after all not improbable that it was a joint production--his and Roebuck's--
