636 DINOSAURIA OF THE CAMBRIDGE GREENSAND. 
Discussion. 
Mr. Cuarteswortu dwelt on the importance of practical experi- 
ments on the effects of exposure and maceration on bones, such as 
those carried out by the author of this paper. 
Mr. Hvurxz bore testimony to the great value of Prof. Seeley’s 
researches ; but said he always felt doubt on the safety of putting 
together the disjecta membra obtained by diggers and coprolite- 
washers. He also expressed doubt as to the generic distinctness of 
Anoplosaurus and Acanthopholis. Of the truly Dinosaurian cha- 
racter of most of the specimens brought forward by the author of 
the paper there was no doubt whatever. 
Prof. SEELEY was aware of the difficulty of dealing with such 
specimens, but had given his reasons for associating the scattered 
bones laid before the Society.
