Note 532 — BOOK XII. THE NATURAL HISTORY OF TREES.

Fée remarks, that at the present day we are acquainted only with one kind of myrrh; the fragments which bear an impression like those of nails being not a distinct kind, but a simple variety in appearance only. He thinks, also, that Pliny may very possibly be describing several distinct resinous products, under the one name of myrrh. An account of these various districts will be found in B. vi. c. 32.
