I send you enclosed a mandate for 396 francesconi, which is what M. Torlonia incorrectly designates a hundred pounds--but as we count in the money of the country, that need make no difference to us. I have just finished an additional act to “Prometheus,” which Mary is now transcribing, and which will be enclosed for your inspection before it is transmitted to the bookseller. I am engaged in a political work--I am busy enough, and if the faculties of my mind were not imprisoned within a mind, whose bars are daily cares and vulgar difficulties, I might yet do something--but as it is-- Mary is well--but for this affair in London I think her spirits would be good. What shall I--what can I--what ought I to do? You cannot picture to yourself my perplexity. Adieu, my dear friends. Ever yours, faithfully attached, P. B. S. TO MR. JOHN GISBORNE. _Florence, Jan. 25th, 1820._ My dear Sir, We have suddenly taken the determination to avail ourselves of this lovely weather to approach you as far as Pisa. I need not assure you--unless my malady should violently return--you will see me at Leghorn. We _embark_; and I promise myself the delight of the sky, the water, and the mountains. I must suffer at any rate, but I expect to suffer less in a boat than in a carriage. I have many things to say, which let me reserve till we meet. I sympathise in all your good news, as I have done in your ill. Let Henry take care of himself, and not, desiring to combine too many advantages, check the progress of his recovery, the greatest of all. Remember me affectionately to him and to Mrs. Gisborne, and accept for yourself my unalterable sentiments of regard. Meanwhile, _consider well your plans_, which I only half understand. Ever most faithfully yours, P. B. Shelley. TO MR. AND MRS. GISBORNE. _Pisa, Feb. 9th, 1820._ Pray let us see you soon, or our threat may cost both us and you something--a visit to Livorno. The stage direction on the present occasion is, “exit Moonshine and enter Wall;” or rather four walls, who surround and take prisoners the Galan and Dama. Seriously, pray do not disappoint us. We shall watch the sky, and the death of the Scirocco must be the birth of your arrival. Mary and I are going to study mathematics. We design to take the most compendious, yet certain methods of arriving at the great results. We believe that your right-angled Triangle will contain the solution of the problem of how to proceed.
