A minute description of this bone was given by the professor, who pointed out the peculiar interest of this discovery on account of the remarkable character of the existing fauna of New Zealand, which still includes one of the most extraordinary birds of the struthious order ("running birds"), viz. the Apteryx, and also because of the close analogy which the event indicated by the present relic offers to the extinction of the Dodo in the island of Mauritius. On the strength of this one fragment he ventured to assert that there once lived in New Zealand a bird as large as the ostrich, and of the same order. This conclusion was more than confirmed by subsequent discoveries, which he anticipated; and, as we shall see, his estimate was a most moderate one, for the extinct bird turned out to be considerably larger than the ostrich. Later on he received from a friend in New Zealand news of the discovery of more bones. In 1843 a collection of bones of large birds was sent to Dr. Buckland, Dean of Westminster, by the Rev. William Williams, a zealous and successful Church missionary, long resident in New Zealand. On sending off his consignment Mr. Williams wrote a letter, of which we give the greater part below. /* "Poverty Bay, New Zealand, February 28, 1842. "Dear Sir, */ "It is about three years ago, on paying a visit to this coast--south of the East Cape, that the natives told me of some extraordinary monster, which they said was in existence in an inaccessible cavern on the side of a hill near the river Wairoa; and they showed me at the same time some fragments of bone taken out of the beds of rivers, which they said belonged to this creature, to which they gave the name Moa. "When I came to reside in this neighbourhood I heard the same story a little enlarged; for it was said that this creature _was still existing_ at the said hill, of which the name is Wakapunake, and that it is guarded by a reptile of the lizard species [genus]; but I could not learn that any of the present generation had seen it. I still considered the whole as an idle fable, but offered a large reward to any one who would catch me either the bird or its protector...." These offers procured the collection of a considerable number of fossil bones, on which Mr. Williams, in his letter, makes the following observations:-- "None of these bones have been found on the dry land, but are all of them from the banks and beds of fresh-water rivers, buried only a little distance in the mud.... All the streams are in immediate connection with hills of some altitude.
