Note 121 — LETTER XXXIII.
Reading edition
The part of the sandy coast, considered by Robinson to be the desert of Sin, has no tarfa bush, much less manna. Concerning the regions where manna is found, Cf. Ritter, p. 665 sqq. That Eusebius also considers the wilderness of Sin to extend to Sinai, is already mentioned. [Σίν, έρημος ἡ μετάξυ παρατείνουσα τῆς Ἐρυθρᾶς Θαλάσσης καὶ τῆς ἐρήμον Σίυα]
