Since he returned to America he has sent me one of the lithographic copies of a very remarkable work he has published on Liniar Associative Algebra It is difficult, and although I cannot study it for more than two hours at a time without being fatigued, I am happy to say I have not lost my facility in mathematics I have several works bearing on the subject in question but I would be much obliged to you if you would send me Sir William Hamilton's lectures on Quarternions- Though I fear there will not be a second edition of my last work during my life, I have brought it up to the present year by adding Tyndalls on the colour of the sky, [Huggins] on the motions of the stars &c. and lastly on the structure of the Sun & the nature of the corona which according to the late observations will probably afford direct proof of the existence of the ethereal medium hitherto hypothetical though on it the undulatory theory of light and all its consequences depend. I am continually adding to the narrative of my life so I have been very busy, besides during the war the newspapers occupied much of my time but I had plenty of it for the autumn and winter have been so bad that I could seldom drive out We had a very short visit from Pentland, he is so much disgusted with the state of Rome that I should not be surprised if he did not return he will surely not pass through Paris in its distracted state I have no sympathy for the French they are so ungrateful for the bounty of England. The British fleet has been here for a short time, I had a visit from Admiral [¿]ton who is an old acquaintance, a first rate iron clad remains supplied to be as a refuge for the Pope, but he seems to be inclined to remain at the Vatican protected by his troops. Our beautiful view is shut out by a wooden building for a Naval exposition and will be for some months which is great nuisance I hear it does not promise much My daughters unite with me in kind remembrances to Mrs and Miss Murray. Yours very sincerely Mary Somerville 1871 Apl 5 Somerville Mrs
