Note 2 — Chapter VIII

We have already stated, on the authority of Pliny, that the Philænean Altars were of sand; and as they must be looked for in this neighbourhood, we have supposed them to have been erected in the sandy tract which we shall shortly mention in our progress eastward from Bengerwàd. For had they been raised on a spot where other materials could have been easily obtained, it is not probable that any so unstable as sand would have been used for the commemoration of so noble an action as that which occasioned their erection.
