Two more original letters in Csoma’s handwriting are extant, written by him at Kanum, and addressed to Mr. B. H. Hodgson, resident at Katmandú, in answer to certain questions which that gentleman addressed to Csoma. These documents also are now in the possession of the Hungarian Academy of Sciences. They were generously presented by Mr. Hodgson in 1882, with a request for them to be preserved among the relics of the late Tibetan scholar, in the archives at Budapest. These letters refer to questions of much scientific interest at the period when they were written, and throw light upon the history of Buddhistic literature, when Hodgson and Csoma were fellow-labourers in the same field of Oriental learning. They have not been published before, and deserve, therefore, to find a place in this biography. The first letter is dated 30th December 1829, and reads thus: “Sir,—I beg to acknowledge the receipt of the volume you have favoured me with, which reached me on the 21st instant. I feel much obliged for the kindness you have done me, in making me acquainted with the names and contents of so many valuable works you have brought to public notice, and with many other things respecting Buddhism in Nepal. Since you desired me that I should make any remarks on the twelfth article of the volume, I beg you will kindly accept of some observations I take the liberty to make on the subject. And I beg to have me excused for my not having been more particular, as perhaps you had expected from me; my circumstances have not permitted me to do otherwise. 2. “(With reference to p. 410, &c.) Tibetan words, if written properly, are very distinct for the eye, but very confused for the ear, as they are generally uttered. In the whole of Tibet there is but one mode of writing, with respect to orthography; there are several ways of pronunciation, according to the several distant provinces. Hence that great discrepancy in the catalogues of Tibetan words furnished by several Europeans. There are to be found in Tibet several examples of alphabets used anciently in India. The late Mr. Moorcroft had sent to Calcutta a copy of the same set that have been exhibited in the plates. The Lantsa letters and their skeletons (that have been likewise represented on the same plate) are used sometimes by the Tibetans now too for inscriptions. They generally use their own characters, either the capital or the small. Their literature in general is contained in books written in any of these two. When one is acquainted with the principles of the Tibetan language, he can read easily both.
