“I am very much obliged to you for the copy of your ‘Manual of the Birds of New Zealand,’ which you have been good enough to send me. I regard it as being in every respect a work of great value; and it possesses this great advantage, that from the Diagram of a Bird which you have introduced into it, to illustrate the technical terms used in describing the various species, and from the lucid language in which each bird is described, you have rendered your work a most valuable introduction to the study of the science of ornithology, with the aid of which any student may readily master that subject in so far as it relates to New Zealand, and thoroughly understand any other ornithological work that he may read. In this respect you have rendered a great benefit to the youth of New Zealand.
