terially improved. I have, therefore, taken the present opportunity of acknowledging the readiness with which this additional information has been supplied, and of offering Mr. Brown my best thanks.
It now only remains for me to add, that the views with which these volumes are illustrated were engraved by Mr. Finden from my own sketches on the spot: the charts, which are reductions of those in the Admiralty Atlas, were engraved by Mr. Walker; and the three plates of Natural History by Mr. Curtis, from drawings made from the specimens by himself, by Henry C. Field, Esq., and by Miss M. Field; to each of whom I take this opportunity of returning my best thanks, and also of bearing testimony to the correctness with which the respective subjects have been represented.
London, March 20th, 1826.
