First edition, one of the rare copies on Japan paper, of which no mention is made. Half dark blue shagreen binding, smooth spine richly decorated with gilt typographical and floral motifs, some rubbing traces on one joint and the lower headcap, gilt fillet outlining the marbled paper boards, pebbled paper endpapers and pastedowns, original wrappers preserved, top edge gilt. A handsomely bound copy. Provenance: from the personal library of Gustave Le Bon with his bookplate representing Buddha meditating in the lotus position pasted on a pastedown.
