τὸν πταρμὸν. This was one of the remedies prescribed by Eryx. in 185 E, hence the def. article. προσφέρειν is a vox propria for medical “applications,” cp. 187 E, 268 A; Hippocr. de flat. 1 οἷος τ᾽ ἂν προσφέρειν τὰ ξυμφέροντα τῷ σώματι: id. de affect. 1 ο_σα δὲ τοὺς χειροτέχνας εἰκὸς ἐπίστασθαι καὶ προσφέρειν καὶ διαχειρίζειν κτλ.

τὸ κόσμιον. This is in ridicule of the theory of medicine stated in 186 C ff and of the use of the term κόσμιος in 187 D, 188 C.

[Ἀριστόφανες]. I follow Sauppe and Hug in regarding the proper name as a gloss on ὠγαθέ: as a rule, ὠγαθέ stands alone.
