[Footnote 1: By the well-known eminent anatomical artist, Mr. Flower, of 22, Lambeth Terrace, Lambeth Road.] The condition and position of the bones, and the nature of the deposit,--evidently an ancient morass, in which the New Zealand flax (_phormium tenax_) once grew luxuriantly,--remind us of the very similar circumstances in which the extinct gigantic Elks in Ireland, and the Mastodons in America, have occasionally been found engulfed in peat bogs and morasses; and, as my son emphatically observes, it is impossible to arrive at any other conclusion than that the Moa to which these feet belonged, had sunk down in the swamp, and perished on the spot. Vertebræ and other parts of a skeleton of a bird of the same proportions, were dug up near the feet. As the specimens under examination are the first examples in which the entire series of the phalangeal and ungueal bones have been found in natural connexion with the metatarsals, I subjoin the admeasurements of the several parts, to render the peculiar construction of the feet in one species of the lost race of the colossal birds of New Zealand, more obvious to those who may feel interested in the subject.
