to attain an importance far superior to that to which the
Daguerreotype has risen.

The American mind needs a waking up upon the subject, and I
think your book will give a powerful impulse in this direction.
In Germany a high degree of perfection has been reached,
and I hope your countrymen will not be slow to follow.

Your interesting account of the experiments of Mr. Wattles
was entirely new to me, and is another among the many evidences
that when the age is fully ripe for any great discovery,
it is rare that it does not occur to more than a single mind.

Trusting that your work will meet with the encouragement which your trouble
in preparing it deserves, and with gratitude for the undeserved compliment
paid to me in its dedication,

I remain, very sincerely,
Your friend and well wisher,
E. ANTHONY.
