ALS to E. Knight. In English. Date: "[London?] 57 Upper Morton Street, Friday." 1 p., with fragment of address ("E. Kni[ght]) and postal hand stamp to verso. In full: "Dear Knight, I do not wish to neglect a professional pupil, and therefore you are very welcome, to an early or late hour, any Friday you will let me know. Should you wish for a lesson—my suffering with this Concert is terrible—the day of my Second Service [?], was taken again but now I hope it is all right. & beg your acceptance of the inclosed[sic] ticket, and give the letter to Mr. Knight with my Comp[imen]ts [?], that was ready for you this morning—be so kind to send me the title of the German grammair Mrs. Ries {?] has given you—Yours sincerely  Ferd[inand] Ries." Text of letter is complete but address to verso is not; remaining leaf was probably second sheet of a bifolium. "Mr. E. Knight" remains unidentified. 7.25 x 4.25 inches (18.5 x 10.5 cm).

An interesting if somewhat mysterious letter from the German composer who was a pupil and secretary of Beethoven.
