[1] The transmitted headword ἡβός is otherwise unattested, but it is in fact an error for ὑβός : see upsilon 10. In the Hippocratic corpus -- see under next note -- this word occurs at Aphorisms 6.46. See also Theocritus, Idylls 5.43, and LSJ s.v. on both headword and (at web address 1) gloss.
[2] The mss preserve this name as either (abbreviated) Hippost, corrected to Hippokr, or else Hippolytos, and the ethnikon supports Kuster's 'Hippokrates' (iota 564, iota 565, iota 566, iota 567, iota 568, iota 569).
