DISCOVERY OF THE ICHTHYOSAURUS. Nearly forty years ^ 

 elapsed since the attention of the scientific world was first 

 directed to the fossil remains of this extraordinary tribe of^ 

 marine reptiles by a memoir, by the late Sir Everard Home, on j 

 a cranium, and other parts of the skeleton, that were exhibited 

 in the then celebrated museum of Mr. Bullock, in Piccadilly. 

 Teeth, vertebrae, and other detached parts of the skeleton of! 

 these animals, had attracted the notice of the earlier collectors 

 of British fossils ; but until Sir Everard Home's communi- ! 

 cation to the Royal Society, in 1814, no definite idea as to 

 the nature of the originals had been entertained. The ano-|j 

 malous character of these fossil skeletons, which in certain 

 parts of their structure resembled those of fishes, and in; 

 others those of crocodiles, suggested the name, so happily 

 chosen by my friend Mr. Kb'nig, the accomplished " Keeper of 

 Mineralogy and Geology of the British Museum," of Ichthyo- \ 

 saurus, 1 or fish-like lizard ; a name by which this group 



a fish, and Saupos, lizard.
