W. Carpenter, Esq., Baltimore.
Dear Sir,--I am obliged to you for the copy of your "One Hundred
Proofs that the Earth is not a Globe," and for the evident kindness of
your intention in dedicating the work to me. The only further remark
it occurs to me to offer is that I call myself rather a student of
astronomy than an astronomer.
Yours faithfully,
RICHARD A. PROCTOR.
P.S. Perhaps the pamphlet might more precisely be called "One hundred
difficulties for young students of astronomy."
