14 Dr. H. Woochoard — On Iguanodon Manfelli. 



M. Fages, the Director of the Bernissart Coal-mining Companj'-, 

 deserves the thanks of all scientific men for his liberality in aiding 

 in so generous a manner this important undertaking. 



After seven years' labour, two huge entire skeletons adorn the 

 great glass case in the Court-yard of the Museum in Brussels. That 

 of ',Iguanodon Bernissartensis cannot be less than 15 feet in height, 

 and measured along the dorsal line is rather over 30 feet in length, 

 covering nearly 24 feet of ground in its erect position. That of 

 Iguanodon Mantelli (see Plate I.) is less in size, and its bones are 

 more slender generally. Its height is rather over 10 feet ; its total 

 length, measured along the back, is about 20 feet, and it covers in its 

 erect position (as represented in our Plate) 12 feet of ground. 



These magnificent specimens, which I have had the good fortune 

 to visit and study repeatedly, during the j)ast five years of their 

 development, are unrivalled, and their reconstruction reflects the 

 highest credit on M. L. F. De Pauvv, the accomplished controller of 

 the workshops in the Royal Museum of Natural History, Brussels, 

 of whose ability as a modeller and reconstructive anatomist I had oc- 

 casion to speak in high praise, in reference to his reconstruction of 

 the Mammoth's skeleton noticed in 1871 (see Geol. Mag. Vol. 

 Yin. pp. 193-8, PI. IV.), also set up in the Eoyal Museum, 

 Brussels. The task of working out these fossils, originally begun by 

 M. G. A. Boulenger, was subsequently undertaken by M. M. L. 

 Dollo, on M. Boulenger leaving the Brussels Museum to join the 

 Zoological Staff of the British Museum, London, in 1882. 



M. Dollo has already published five Memoirs on " Iguanodon " ; ^ 

 one on the Batrachians ; '^ one on the Chelonians ; ^ and one on the 

 Crocodiles * of Bernissart. 



A complete figure of Iguanodon Bernissartensis was published in 

 1883, and reproduced in "Nature" (Sept. 6, pp. 439-43) by Prof. 

 H. N. Moseley, F.R.S., who gives an excellent account of the 

 Brussels Iguanodon. 



In the present year the reconstruction of Iguanodon Mantelli has 

 heen completed and the figure of the skeleton published. From this 

 our reproduction on Plate I. is derived. 



It is hardly possible to over-estimate the importance of the 

 Bernissart discoveries, or the flood of light which they throw upon
