I have examined the Catalogue of the Library respecting the Art and Science of Warfare. It is but poorly furnished with the most instructive works published during and after the wars of Napoleon. It is the same with the United Service Institution, where I was admitted for the purpose of consulting the books which I required for the composition of the military work that I have in hand, and I have in consequence had to order various books from France at my own expense; but, however, I shall soon have to study the work of which I send you the title: “La grande Tactique du Marquis de Ternay,” Colonel of the Staff. These works, especially that of Martray, I could not procure on account of the expense, but should you think it desirable for the Library to acquire them, it would be of great assistance to me. The Paris edition of Ternay’s work ought not to cost more than 25 francs, and that of Brussels much less. The work which I am engaged upon will be in English, and contain all the information required by officers in the field, from the Sub-Lieutenants of the three branches of which an army is composed, up to the Chief Staff Officer inclusive. It is a serious undertaking as it must be restricted to a portable volume, and include, with clearness and conciseness, the _omne scibile_ of military affairs. With diligence and assiduity, assisted by the studies of my youthful days, I promise myself I shall succeed; still it is a work I shall not be able to finish in less than six or eight months. While thus engaged, I could devote some hours a day to other occupations, and I should like, if possible, to give lessons in the Italian language, literature, and in military art and science. Having been myself major of the staff, I can give good lessons in the latter, and am tolerably conversant with the former. Up to the present time my life has been unusually eventful, and passed mostly amidst dangers—a constant source of anxiety to my family, who have suffered no slight losses on my account. As I am a little more quiet just now, I wish to derive advantage from my acquirements, while awaiting the longed-for moment when I may once again take up arms for our independence. I have been advised to advertise in the _Times_ that I am willing to give lessons; I should not like to do this, it would seem as if I wished to turn my good name to profit, although, instead of such an expedient, I think, if you would, you might greatly assist me amongst your acquaintances, and in any case I am quite ready to follow your advice. With my private life you are not, however, acquainted; but on this I give you full liberty to apply even to my adversaries, whether in opinion, or party, or otherwise, for we all have such. Of languages, I know French well, and for private lessons can make myself understood in English. I have written this to avoid troubling you, and if you
