D. page 117. FEET OF DINORNIS ROBUSTUS.-As the specimens described in the text are the only perfect series of the bones of the feet hitherto found in juxtaposition, the dimensions of the principal parts will interest the Ornithologist; but I must refer for details to my Memoir on the Geology of New Zealand, "Journal of the Geological Society of London," vol. vi. p. 338; or to "Pictorial Atlas of Organic Remains," p. 10.

Tarso-metatarsal: length, 17 inches; circumference of proximal end, 11; of the distal end, 15.

Toes: length of the inner toe, 9 inches; middle toe, 111⁄2; outer toe, 9.

Middle toe length of first phalanx, 44 inches; second, 23; third, 1; fourth or ungual bone, 3 inches.

E. page 229.-The following is another extract from the eloquent Address of Sir Charles Lyell on that occasion, (Feb. 20, 1835.)—“ The Wollaston Medal has been awarded to Mr. Mantell for his discoveries in Fossil Comparative Anatomy, particularly of the genera Iguanodon and Hylæosaurus.' There are few of you, gentlemen, I believe, entirely unacquainted with the results of Mr. Mantell's investigations in this department of science,-few who have not either read of them in his works, or seen them in his splendid Museum. That collection, now at Brighton, which has already been visited by thousands of persons, is of itself a monument of original research and talent, well deserving, even if he had never written on the subject, as high a mark of distinction as the Society has conferred upon Mr. Mantell this day. It is an assemblage of treasures which the mere industry of a collector could never have brought together, and which wealth alone, even had Mr. Mantell possessed it, could not have purchased. It required his zeal, inspired by genius and directed by science, to bring to light, and, as it were, call into existence, so many monuments of the former state of the animate creation. Gentlemen, you will, I am sure, allow me to dwell somewhat at length on this topic, as one which is to me of no ordinary interest, for it is now nearly twenty years since I first had the good fortune to become acquainted with Mr. Mantell; before I had the honour of knowing any one of the leading members of this Society; before, indeed, I had heard of the existence of the Society itself. At that time the collection at Lewes was in its infancy, yet contained osteological remains of that class, for the illustration of which it has since become so celebrated; even at that time my friend had indulged sanguine anticipations, from seeing only a few bones and teeth, of the splendid discoveries he should make in regard to these gigantic saurians; even then he foresaw some of the results which have since been realized. I had afterwards many opportunities of revisiting Lewes, more than once in

company with Dr. Buckland, and after each interval found Mr. Mantell's Museum enriched with new discoveries, some of his former theories and conjectures confirmed, and new views opening upon his mind. Mr. Greenough has pointed out to you how strikingly a recent discovery of an assemblage of the bones of the Iguanodon grouped and imbedded in one mass of rock, has shown the sagacity with which Mr. Mantell had put together the disconnected remains when first discovered. All the bones in that specimen are such as he had previously considered as belonging to the Iguanodon, with no intermixture of those which he had rejected as probably referable to other saurians."

F. page 232.-Baron Cuvier on the Iguanodon. For the reasons stated in the text, I would beg the paleontologist who may feel any interest on this subject to peruse M. Cuvier's remarks on the teeth of the Iguanodon, in "Ossemens Fossiles," tome v. pp. 351, 352. The only other notice of the Iguanodon by this illustrious philosopher, is in the edition of his "Discours sur les Revolutions de la Surface du Globe," published in 1826. "Les sables ferrugineux placés en Angleterre audessous de la craie, contiennent en abondance des crocodiles, des tortues, des mégalosaurus, et surtout un reptile qui offrait encore un caractère tout particulier, celui d'user ces dents comme nos mammifères herbivores. C'est à M. Mantell, de Lewes en Sussex, que l'on doit la découverte de ce dernier animal, ainsi que des autres grands reptiles de ces sables inférieurs à la craie :-il l'a nommée Iguanodon." In August 1830, I submitted to Baron Cuvier, then in London, many teeth and bones from Tilgate Forest, and was confirmed in my opinion as to the probable dentition, and structure of the maxillary organs, of the Iguanodon, by his unqualified approval; and so much was his interest excited, that he made arrangements to visit me at Lewes the following week; but unfortunately the revolution broke out at Paris, and M. Cuvier was summoned from England: we never met again.

G. page 280.-Drawings of Wealden Reptiles presented to Professor Owen. The Wollaston fund, awarded me with the medal by the Geological Society in 1835, amounting to between 20l. and 307., was expended on drawings (by Mr. Dinkel, now of 17, Upper King Street, Bloomsbury,) of the principal bones of the Iguanodon, Hylæosaurus, &c. in my collection, with a view to publication: the Maidstone Iguanodon, the large specimen of Hylæosaurus, and figures of both slabs of the Goniopholis, (in Room III. Case A,) were of imperial 4to size; the remainder were in 4to, and comprised more than one hundred figures. In 1841, the state of my health rendering it improbable that I should ever be able to resume my scientific researches, I presented the whole of these beautiful drawings to Professor Owen, who then contemplated a work on British Fossil Reptiles. A plate of reptilian teeth in Professor Owen's Odontography," and the two lithographs of the Maidstone Iguanodon

1 These remarks refer to the Maidstone Iguanodon, then recently discovered. The Members of the "Palæontographical Society" are requested to compare the above statement with that given in the last Monograph on Cretaceous Reptiles."

in the "Palæontographical Monograph" of the present year, are the only drawings of that series hitherto published.

I. page 335.-The Author's Collection of Fossils from the Chalk and Wealden Deposits of the South-East of England, &c. "When the first edition of this work (The Wonders of Geology') appeared, my collection, consisting of upwards of 20,000 specimens, was exhibited at Brighton by the Sussex Scientific Institution as the Mantellian Museum, with a view to its permanent establishment as the basis of a County Museum. That expectation was, however, defeated; for though I would willingly have made any pecuniary sacrifice to accomplish what appeared to me so desirable an object, yet after the decease of my noble and lamented friends the late Earl of Egremont, and the Earl of Munster, who ardently and liberally supported the measure, the plan was abandoned. I therefore, in compliance with the suggestion of my scientific friends, disposed of the entire collection to the Trustees of the British Museum."-Extract from the Preface to the Second Edition of the "Wonders of Geology." The sum given for this collection, on which I had expended at least 7,000l. during a period of 25 years, was 4,000l.; the expenses and risk of removal from Brighton to London, were incurred by the Trustees.

K. page 367.-Mr. Hawkins's Collection. The specimens figured in the first edition of Mr. Hawkins's "Memoirs of Ichthyosauri," &c. were valued by Dr. Buckland and myself, at the request of the Trustees of the British Museum. The collection consisted of several hundred specimens, and the total amount paid for the same was 1,250l. Among the items were:-The large Ichthyosaurus, (ante, p. 381), 2107. Cranium with orbital plates, (Pl. V.) 257. Ichthyosaurus, (Pl. VII.) 1007. Plesiosaurus; the matchless specimen in Case D. (ante, p. 340), 2007.
