GIANTS AND PIC. MIES. 



is named mantclU. In 1822, about 64 years ago, ^Frs. ^rantoll 

 found the first tooth imbedded in a mass of coarse conglomerate 

 wliich had been brought as ' road m<'tal ' from one of the 

 quarries of the Weahlen formation of Tilgate Forest. Sub- 

 sequently, other teeth and fragmentary remains were found. 

 In 1834 Mr. Hensted found in the Kentish-rag quarries of the 

 Lower (Ireensand formation of Maidstone, a connected series 

 of V)one8 of a young individual en«bedded in stone in a con- 

 fused manner, flattened and distorted. We are sorry to say 

 that sul)sequent discoveries have brought our Iguanodon Into 

 disrepute. In 1878 a remarkable discovery was made in 

 Belgium of a deposit containing twenty three huge Iguanndons. 

 Three years were subs(?qMently spent in extracting them and 

 associate fishes, and reptiles. After seven years' labour two 

 huge entire skeletons have been set up in the Court j-ard of 

 the Museum at Brussels. One is the Lpumodon MantclH, 

 whose height is more than 10 feet, — its total length measured 

 along the back is about 20 feet. In its erect position it 

 occupies 12 feet horizontal s[)ace. Its companion is still 

 larger. The Ljuanodoii lii'rni.xmrtroms is about 15 feet in 

 lieight, — measured along the back it is over 30 feet in length. 

 In its erect position it covers nearly 24 feet of horizontal 

 space. Thus after the space of more than 60 years the true 

 character of these Wealden giants has been fully revealed. Its 

 appearance, when erect, 's Kangaroudike. 



At the Centennial Exhibition, IMiilaikdphia, Mr. Hawkins 

 erected a restoration of the Hadrosauvus Foulldi, whose 

 remains had been found in the Cretaceous beds of New Jersey. 

 This closely resembles the Iguanodon. It was about 28 feet 

 in length. It was jilaced in the English Department, and 

 towered over the passage between it and the Canadian Depart- 

 ment. It was a reproduction of the restoration, with the 

 original remains, which lie had erected in the Museum of 

 the American Academy of Natural Sciences, Philadelphia. 

 America excels in IMnosaurs. Prof. Marsh is entitled to the 

 lionor of making known the largest number. More than thirty 

 genera have b«jen described.
