314? An Attempt to ascertain the Animal 



fossil in conformation and structure. [See in our III. 14. 

 figures of a tooth of the recent iguana, and of teeth of the fossil 

 iguanodon. A figure of the animal, the crested guana, and a 

 notice of its habits, are given in the Penny Magazine^ No. 41.] 



" From the character of the fossil remains which more 

 immediately surround those relics of the iguanodon, it is con- 

 cluded that this animal was amphibious, a native of the fresh 

 water, and not of the ocean : calculating on the proportions 

 of the living animal, and supposing the same relative dimen- 

 sions in the fossil as in the [iguana in relation to its] teeth, the 

 individual which possessed the teeth we have been describing 

 must have been upwards of 60 ft. in length. A similar de- 

 duction has been made by Dr. Buckland respecting the size 

 of the iguanodon, from a femur and other bones in the pos- 

 session of Mr. Mantell. 



M It would appear, from the researches of Mr. Mantell, 

 that the iguanodon bore on its head a remarkable horny 

 appendage, as large as and similarly formed to the small horn 

 of the rhinoceros. What he discovered of this is externally 

 dark brown ; some parts of the surface are smooth, others 

 furrowed, as if for the passage of vessels. Its structure is 

 osseous, and there is no external cavity. It does not appear 

 to have been joined to the skull by a bony process, like some 

 horns of mammiferous animals. The horned species are by 

 far most abundant among existing iguanas. The Iguana 

 cornuta of St. Domingo is like the common species in mag- 

 nitude, colours, and general form; but upon the point of the 

 head, between the eyes and nostrils, are found four large and 

 bony tubercles ; behind them rises an osseous and conical 

 horn, which is enveloped by a single scale. The fossil horn, 

 of which we have been speaking, was beyond all question a 

 dependency of this description : there were even found upon 

 its surface impressions of the tegument by which, in all pro- 

 bability, it was connected with the cranium." 



Such is the description we find given of the iguanodon. 

 [Particulars of additional discoveries, by Mr. Mantell, on the 

 iguanodon, are given in p. 99 — 102. of our current volume. 

 Information on it is given in III. 13, 14, 15. 366.] 



I will now give you, for variety's sake, Harris's translation 

 of that part of the 40th chapter of Job, where the behemoth is 

 described (it differs but triflingly from the Scripture one) ; and 

 I may premise that Harris, being of opinion that the behe- 

 moth was the hippopotamus, cannot be supposed to have 

 humoured his translation at all, so as to make it fit the de- 

 scription of so totally a different animal as the iguanodon must 

 have been :
