Note 1990 — BOOK XV. THE NATURAL HISTORY OF THE FRUIT-TREES.

It is generally thought that this was the only variety known to the ancients; but Fée queries, from the story of Pyramus and Thisbe, which represents the mulberry as changing from white to blood colour, that the white mulberry was not unknown to them; but through some cause, now unknown, was gradually lost sight of.
