Note 1554 — BUTTER.

Historia Animal. iii. 20, p. 384: πᾶν δὲ γάλα ἔχει ἰχῶρα ὑδατώτη, ὃ καλεῖται ὀῤῥὸς, καὶ σωματῶδες, ὃ καλεῖται τυρός. Omne lac habet succum aquosum, qui dicitur serum, et alterum corpulentum, qui vocatur caseus.—P. 388: ὑπάρχει δ’ ἐν τῷ γάλακτι λιπαρότης, ἣ καὶ ἐν τοῖς πεπήγοσι γίνεται ἐλαιώδης. Inest in lacte pinguedo, quæ in concreto oleosa fit. This is the translation of Scaliger; but by Gaza the latter part of the passage is translated as follows: “quæ etiam concreto oleum prope trahit.” It appears to me doubtful what ἐν τοῖς πεπήγοσι properly means. The comparison of oil occurs also in Dioscorides and Pliny. Aristotle, in all probability, intended to say that the fat part of milk was observed under an oily appearance in cheese made of sweet milk from which the cream had not been separated; and that indeed is perfectly agreeable to truth.
