moves. The marvellous resemblance of Cleora lichenaria even 
deceived one of these lizards after the larva had moved more than 
once. The instant the caterpillar became rigid, the lizard was 
puzzled and seemed unable to realise that the apparent piece of 
lichen was good to eat. After a few moments, however, the lizard 
was satisfied, and ate the caterpillar with the keenest relish.”—(The 
Colours of Animals, pp. 40-1.) 
But if it could be shown that the hare was concealed 
by its colour, so as to make it absolutely invisible when 
motionless ; if it could be shown that the animal only 
moved under conditions in which it was perfectly safe to 
do so, it would still be in danger, for it carries with it 
and leaves behind it an aroma which is as delightful to 
the nostrils of the enemy as it is fatal to the concealment 
of the victim. It is conjectured that in classical times one 
kind of dog was employed to find the hare upon its form, 
and others to chase it. It was found by scent and chased 
by sight. The modern huntsman follows as 
“ the patient pack 
Hang on the scent unwearied.” 
And Somerville is so enamoured of this sport that he 
denounces those who hunt the hare by sight in language 
worthy of an ecclesiastical anathema. It may further 
be observed that the hare is as aware of its danger from 
this source as from the quick eyes of those who can see 
through its concealment. So much, then, for the colour 
of the hare, so often quoted as a result of the action of 
Natural Selection, because it is saved by its invisibility. 
But that implication can scarcely be sustained. It is seen 
by the experienced sportsman, while it is quite invisible 
to the novice. It is seen by the merest novice the moment 
that it begins to move. It is found and followed by scent 
as well as by sight. 
In the same way, it can be shown that the protection of 
winter white, which some animals assume, does not confer
