428 T HE WONDERS OF GEOLOGY. Lect. IV. 



This specimen consists of a considerable number of the 

 bones of the inferior portion of the skeleton of an adult, but 

 not aged, individual. The bones are imbedded in the stone in 

 a very confused manner ; few of them lying in their natural 

 order of juxtaposition, and all being more or less flattened 

 and distorted. The following are the most important, and 

 the best preserved ; but there are numerous fragments, too 

 imperfect to admit of determination. 



Two thigh-bones, each 33 inches long. Plate 111. figs, 1, 2. 



One leg-bone {tibia), 30 inches long. Fig. 3. 



Metatarsal and phalangeal bones of the hind feet ; these much 

 resemble the corresponding bones of the hippopotamus. Figs. 

 4, 4, 4. 



A claw-bone {ungueal bone), which was originally covered by a 

 horny investment ; it resembles the corresponding bone of a 

 land tortoise. Fig. 5. 



Two metacarpal bones of the fore feet, each 14 inches in length. 

 Fig. 6. 



A radius, or bone of the fore-arm. Fig. 7. 



Several dorsal and caudal vertebra? (bones of the spine and tail). 

 Figs. 8, 8, 8. 



Fragments of several ribs. Figs. 9, 9, 9. 



Two clamcles, or collar bones, each 28 inches in length, resembling 

 the bone figured Plate IV. figs. 1, 2, Geology of the South-East 

 of England. These bones are of a very singular form, and 

 differ essentially from any known clavicle. Figs. 10, 10. 



Two large flat hatchet-shaped bones, which belong to the pelvis 

 {iliac bones). Figs. 11, 11. 



A chevron-bone, or inferior spinous process of a vertebra of the tail 

 Fig. 12. 



A portion of a tooth, and the impression of another. — The preserva- 

 tion of these relics was most fortunate, as the identity of the 

 animal with the Iguanodon of Tilgate Forest is thereby 

 jompletely established. 



The geological position of this specimen forms an excep- 

 tion to what has been previously remarked of the remains of 

 the Iguanodon from the Wealden ; for while in the latter 

 the bones are associated with terrestrial and fluviatile ex- 

 uviae only, the Maidstone fossil was imbedded in a marine
