My dear Fanny — I am sorry to hear you have been so unwell: now you are better, keep so. Remember to be very careful of your clothing — this climate requires the utmost care. There has been very little alteration in me lately. I am much the same as when I wrote last. When I am well enough to return to my old diet I shall get stronger. If my recovery should be delay’d long I will ask Mr. Abbey to let you visit me — keep up your Spirits as well as you can. You shall hear soon again from me.
Your affectionate Brother
