[Illustration: Fig. 13.--Slab xxv. restored from Stuart (from Michaelis).] Slab xxviii. is original; slabs xxix.-xxxi. are casts from the originals at Athens; No. 65 (on slab xxix.) is a marshal beckoning to the riders. [Rightnote: XXXII.] [Sidenote: 75.] The fragment (in slab xxxii.) containing the head of No. 75 and the horse's head, having been discovered in 1850 in the collection of Sculptures at Marbury Hall in Cheshire, was presented to the Museum in 1850 by J. H. Smith Barry, Esq., the owner of that collection. A small fragment, cast from the original at Athens, and added to slab xxxiv., is not engraved by Michaelis. [Rightnote: XXXV.] [Sidenote: 85.] The fragment (in slab xxxv.) which contains the head of No. 85 and of a horse, after having been in the possession of the Society of Dilettanti, passed from that body to the Royal Academy, by whom it was presented to the British Museum in 1817. [Rightnote: XXXVII.] [Sidenote: 89.] The fragment (in slab xxxvii.) containing the head of No. 89 and a horse's head, of which a plaster cast is adjusted to the marble, is now at Athens. [Rightnote: XXXIX.] [Sidenote: 97.] The head of No. 97, on slab xxxix. was formerly in the Pourtalès Collection, at the sale of which in 1865 it was purchased for the British Museum, and inserted in its place on the frieze. [Rightnote: XLII.] [Sidenote: 107.] [Sidenote: 106.] On the last slab of the north side, the procession is still in a state of preparation, so that this slab prepares a transition to the west side. In the foreground is a rider (No. 107), standing by his rearing horse, whom he holds by the rein with his right hand. In the background beyond this group is a mounted figure (No. 106), so entirely concealed by the rearing horse in the foreground that the only evidence of his presence is his right hand advanced just beyond his horse's shoulder point. [Sidenote: 109.] [Sidenote: 110.] To the right is a rider (No. 109) standing by his horse, and in the act of drawing down his chiton under his girdle in front, while a youthful attendant (No. 110) assists him by pulling it down behind, or perhaps by tying the lower girdle over which the folds were drawn. The attendant carries on his shoulder a folded chlamys, probably that of his master. WEST FRIEZE OF THE PARTHENON. [Sidenote: =326.=]
