oe GREAT FISH-LIZARDS 61 
breast-bone of a lizard, the paddles of a whale or dolphin, and the 
vertebree of a fish! No wonder that naturalists and palezonto- 
logists, whose realm is the natural history of the past, were obliged 
to make a new division, or order, of reptiles to accommodate the 
fish-lizard. It is obvious that a creature with such very “mixed” 
relationships would be out of place in any of the four orders into 
which living reptiles, as represented by turtles, snakes, lizards, 
and crocodiles, are divided. Here is what our late friend Professor 
Blackie said of the Ichthyosaurus— 
* Behold, a strange monster our wonder engages ! 
If dolphin or lizard your wit may defy. 
Some thirty feet long, on the shore of Lyme-Regis, 
With a saw for a jaw, and a big staring eye. 
A fish or a lizard? An ichthyosaurus, 
With a big goggle eye, and a very small brain, 
And paddles like mill-wheels in chattering chorus, 
Smiting tremendous the dread-sounding main.” 
A glance at our restoration, Plate IV., will show that the fish- 
lizard was a powerful monster, well endowed with the means of 
propelling itself rapidly through the water as it sought its living 
prey, to seize it within those cruel jaws. The long and powerful 
tail was its chief organ of propulsion; but the paddles would 
also be useful for this purpose, as well as for guiding its course. 
The pointed head and generally tapering body suggests a capa- 
bility of rapid movement through the water; and since we know 
for certain that it fed on fishes, this conclusion is confirmed, for 
fishes are not easily caught now, and most probably were not 
easily caught ages ago. 
The personal history of the fish-lizard, merely as a fossil or 
“remain” is interesting; so much so, that we may perhaps be 
allowed to relate the circumstances of his début before the 
scientific world, in the days of the ever-illustrious Cuvier, to
