Palms and birches are both found in Asia Minor; but I permitted them to grow side by side, thereby committing an offense against the geographical possibility of vegetable existence.

The birch, in this locality, flourishes in the mountainous region, the palm, according to Griesbach (Vegetation of the Earth, Vol.

I, p.

319) only appears on the southern coast of the peninsula.

The latter errors, as I previously mentioned, will be corrected in the new edition.
