Within Emile Littreés classification of Hippocratic works, class ten consists of three lost works, two of which appear to have been treatises on the treatment of serious wounds and on the extraction of arrows. The sources for their titles—Erotian, Galen, an eleventh-century Arabic MS and the twelfth-century MS Vat.graec.276–disagree on minor points, but it is clear that they are all referring to the same works.
