obligations and sincere thanks to the Peninsular and Oriental Steam
Navigation Company, for conveying, without charge, all small parcels
of books, instruments and specimens, addressed to or by myself.

snare; nor, I regret to say; has the lithographer, in all cases, been
content to abide by his copy. My drawings will be considered tame
compared with most mountain landscapes, though the subjects comprise
some of the grandest scenes in nature. Considering how conventional
