Before the reader proceeds to the perusal of the following Memoir, it may be proper to inform him—that the first and second parts of it have been chiefly selected from various Journals, which Mr. Martyn was in the habit of keeping, for his own private use, and which, beginning with the year 1803, comprehend a period of eight years. The third part is extracted from an account which he drew up of his visit to Shiraz in Persia; in which some occasional observations on the state of his own mind and feelings are interspersed. It is termed a Narrative by Mr. Martyn: and had his life been spared, it was probably his intention to have enlarged it, for the use of the Public, or perhaps to have communicated it, nearly in its original shape, to his intimate friends. From the style and manner of it, at least, it may be presumed not to have been exclusively intended (as the Journals above-mentioned evidently were) for his own recollection and benefit.—The greater part of these papers were upon the point of being destroyed by the writer, upon his undertaking the voyage to Persia; but, happily, he was prevailed upon, by the Rev. D. Corrie, to confide them under a seal to his care, and by him they were transmitted from India, to the Rev. C. Simeon and J. Thornton, Esq. Mr. Martyn's executors, in the year 1814.
