THE AMERICAN NATURALIST [Vol. XLIV 



the splendid specimen in the Carnegie Museum, replicas 

 of which have been generously presented by Mr. Andrew 

 Carnegie to a number of the leading museums of Europe. 



In The Field (London) of August 26, 1905, Mr. F. W. 

 Frohawk, a well-known English illustrator, published a 

 note, in which he said, among other things: 



The visitor to the Reptile Gallery of the Natural History Museum can 

 not fail to be struck by the extraordinary pose of the gigantic skeleton. 

 ... It would be interesting to know the reason for mounting the 

 specimen so high on its legs, like some lm-e pachyderm. As it is a 

 inumitic lizard, why should it not be represented in the attitude usually 

 assumed by such animals? . . . Doubtless there is some good reason 

 for mounting it in such an attitude; if so, information on the subject 

 would be welcome. 



No reply was given to this query, except incidentally 

 by Professor (now Sir) E. Ray Lankester, who said in a 

 newspaper interview that "the laterally compressed 

 form of the body, according to the opinion of American 

 students, precludes the idea that the animal could have 

 crawled upon its belly. ' ' 



Shortly after the restored skeleton of Brontosaurus 

 excelsus, which is one of the ornaments of the American 

 Museum of Natural History, had been erected, Messrs. 

 Otto and Charles Falkenbach, assistants in the paleonto- 

 logical laboratory of that museum, made a model, in 



which they attempted to show the Brontosaurus in a 

 crawling attitude. I am indebted to Dr. W. D. Matthew 

 for an illustration of this model, which is herewith 

 reproduced (Fig. 1). This model was discussed at the 

 meeting of the American Society of Vertebrate Paleon-
