[ Richard Owen ] Autograph Letter Signed ('Rd. Owen') to an unnamed correspondent.

Two pages, 12mo, fold marks, good condition, text clear and complete. My first lecture I published in May last 'On the Classification & Geographical Distribution of Mammalia" | 8vo Parker's, Strand. | The matter of the other three lectures will appear in a work on fossil Mammalia in the Press (Murray) [presumably "Summary of the succession in time and geographical distribution of recent and fossil Mammalia " (1859)]
