To JOHN GEORGE CHILDREN, Esquire, F. R. S. L. & E.
The kindness which a traveller receives when in a distant land, must
ever be among his most pleasing recollections your attentions therefore
to me, during any short residence in London a few years since, cannot
easily be forgotten. Suffer me, then, to inscribe this little work to
you as a token of my gratitude.
Our pursuits in the Natural and Physical Sciences have been congenial.
Your interesting researches with your original and magnificent Galvanic
Battery, first drew my attention to the calorific effects of that
mysterious agent; and your works on Natural History have stimulated my
exertions in the same fascinating pursuit.
A large portion of your time and fortune have been devoted to the
patronage or the cultivation of Natural Science so that the dedication
of this work to you, if it were infinitely more worthy of your
acceptance, would be due from me, both as a tribute of high respect, as
well as of grateful acknowledgment.
