[Footnote 151: The foolish fashion of this citron-wood
prevailed at Rome among the men, as much as the taste for
pearls among the women. A round board or table, four or five
feet in diameter, sold for the price of an estate
(latifundii taxatione), eight, ten or twelve thousand pounds
sterling (Plin. Hist Natur. xiii. 29). I conceive that I
must not confound the tree citrus with that of the
fruit citrum. But I am not botanist enough to define
the former (it is like the wild cypress) by the vulgar or
Linnaean name; nor will I decide whether the citrum be the
orange or the lemon. Salmasius appears to exhaust the
subject, but he too often involves himself in the web of his
disorderly erudition (Plinian. Exercitat. tom. ii. p. 666,
etc.).]
