Bones of the IgiiamxJon. 201 



Lewes) of the circumstance, and that 'gentleman visited Maid- 

 stone a few days since, and has communicated to us the follow- 

 ing remarks on those extraordinary osteological remains. 



" The mass of stone in which the bones are imbedded will, 

 when united, form a surface of 8 feet by 7, its thickness vary- 

 ing from a few inches to 2 feet : it consists of the hard variety 

 of the limestone called Kentish rag, which is well known in the 

 south-east of England as an excellent building stone. It abounds 

 in the marine shells characteristic of the deposit, viz. GerviUuBj 

 TrigonicB^ Terebratuke, &c. The surface exhibits a confused 

 layer of large bones, more or less broken, and all of them, with 

 the exception of a few vertebra*, lying without any order or 

 connexion. The following were sufficiently exposed to admit 

 of their characteristics being determined. 



"Two femurs or thigh-bones, each 33 inches in length. 



" One tibia and fibula, about 30 inches in length. 



" Several metatarsal and phalangeal bones. 



" Two unguical or daw-bones (the distal pludangeal) : these 

 very closely resemble the nail-bones of a very large land tortoise, 

 and differ essentially from the claw-lx)ne figured in the Geology 

 of the South-East of England. 



** Several caudal, and a lumbar vertebrae. 



" Fragments of many ribs. 



" Two of those extraordinary bones figured in the Geology 

 of the South-East of England, plate iv. figs. 1, J^, and which 

 probably are clavicles. 



" A fragment of one tooth, and the impression of another, 

 decidedly of the Iguanoddn. 



" There are portions of many other bones visible, and should 

 the proprietor clear away the surrounding stone with care and 

 skill, there can be no doubt that much additional light will Ix? 

 thrown on the osteology of the Iguanodon. Anxious to trans- 

 mit this hasty notice in time for the Edinburgh New Philoso- 

 phical Journal, I must not indulge in any remarks on this soli- 

 tary and interesting fact of the occurrence of the remains of the 

 gigantic lizard of the Wealds in the marine arenaceous beds of 

 the chalk.
