TO ROBERT JAMESON, ESQ.

PROFESSOR OF NATURAL HISTORY IN THE UNIVERSITY OF EDINBURGH,

This small Volume is respectfully inscribed by the Author, as a token of gratitude for his kindness to himself, as a Memorial of the friendship and patronage extended by him to the Gentlemen, the incidents of whose lives it records, and as a Testimony of the estimation in which his character is held for his assiduous cultivation of Physical Science in all its branches, and for his unwearied, enlightened, and generous efforts to inspire, not only the Students of his class, but the Public at large, with a love for the study of Nature.
