Note 520 — I.—PHÆNOGAMOUS OR FLOWERING PLANTS. (continued 4)

The λίβανος of the Greeks, the Latin Olibanum, as well as the Arabic Lubân, and the analogous sounds in other languages, are all derived from the Hebrew Lebonah, signifying milk: and modern travellers who have seen the frankincense trees state that the fresh juice is milky, and hardens when exposed to the air. The word Thus, on the other hand, seems to be derived from the verb θύειν, to sacrifice.
