It was owing to Jane's untiring exertions at this time that her health began to suffer. One other consequence too, but of a less tragical kind, was due to Henry's illness. The physician that attended him--supplementing, no doubt, Mr. Haden--was one of the Prince Regent's physicians, and he, either knowing or hearing (for it was now an open secret) that Jane Austen was the author of _Pride and Prejudice_, informed her that the Prince greatly admired her novels, 'that he read them often, and kept a set in every one of his residences; that he himself had thought it right to inform His Royal Highness that Miss Austen was staying in London.' The Prince did not so far condescend as to desire to see Miss Austen in person, but he instructed his librarian, Mr. Clarke, to wait upon her and show her any civility in his power. The result was that on November 13 Jane was shown over the library and other apartments at Carlton House, and in the course of the visit Mr. Clarke announced that if Miss Austen had any other novel forthcoming, she was at liberty to dedicate it to the Prince. We cannot tell what may have been the exact amount of pleasure given to Jane by this piece of information, as Cassandra was at that time also in Hans Place, and there is therefore no letter of Jane to her on the subject. But, at any rate, Jane was loyal enough to wish to do what was right and proper in the circumstances. Consequently, on November 15, we find her writing to Mr. Clarke as follows:-- SIR,--I must take the liberty of asking you a question. Among the many flattering attentions which I received from you at Carlton House on Monday last, was the information of my being at liberty to dedicate any future work to His Royal Highness, the Prince Regent, without the necessity of any solicitation on my part. Such, at least, I believed to be your words; but as I am very anxious to be quite certain of what was intended, I entreat you to have the goodness to inform me how such a permission is to be understood, and whether it is incumbent on me to show my sense of the honour by inscribing the work now in the press to His Royal Highness; I should be equally concerned to appear either presumptuous or ungrateful. To which Mr. Clarke replied:-- Carlton House: November 16, 1815. DEAR MADAM,--It is certainly not _incumbent_ on you to dedicate your work now in the press to His Royal Highness; but if you wish to do the Regent that honour either now or at any future period, I am happy to send you that permission, which need not require any more trouble or solicitation on your part.
