Living from day to day, without a plan for four-and-twenty hours to come, I form no catalogue of impossible events. Laid up in port for life, as I thought myself at one time, I am thrown out to sea, and an unknown one to me. By so slender a thread do all our plans of life hang! My hand denies itself farther, every letter admonishing me, by a pain, that it is time to finish, but my heart would go on in expressing to you all its friendship. The happiest moments it knows are those in which it is pouring forth its affections to a few esteemed characters. I will pray you to write to me often. I wish to know that you enjoy health and that you are happy. Present me in the most friendly terms to your mother and brother, and be assured of the sincerity of the esteem with which I am, dear madam, your affectionate friend and humble servant, TH. JEFFERSON. Among the many pleasant friendships formed by Jefferson in Paris, there was none that he prized more than that of Mr. and Mrs. Cosway. Both were artists; but the husband was an Englishman, while the wife was born under the more genial skies of Italy. Possessing all that grace and beauty which seem to be the unfailing birthright of an Italian, she united to a bright and well-cultivated intellect great charms of manner and sweetness of disposition. Her Southern warmth of manner, and the brilliancy of her wit and conversation, were fascinations which few could resist, and which made her one of the queens of Parisian society. In Jefferson she found a congenial friend, and held his worth, his genius, and his learning in the highest estimation. When her husband and herself left Paris, she opened a correspondence with him, and it was at the beginning of this correspondence that he addressed to her that beautiful and gracefully written letter, called the "Dialogue between the Head and Heart," which is found in both editions of his published correspondence. Mrs. Cosway's own letters are sprightly and entertaining. I have lying before me the originals of some that she wrote to Jefferson, from which I give the following extracts, only reminding the reader that they are written in a language which to her was foreign, though the Italian idiom adds grace and freshness to the sweet simplicity of these letters. Many of them are without date. _Mrs. Cosway to Thomas Jefferson._ Paris, ----, 1786.
