AFRICA. 7^ 
femairi quiet before the dog, it Is not fo mucli 
from a fudden impulfe of fear as from de- 
liberate cunning. While clofe upon the ground 
they imagine themfclves to be concealed from 
the enemy. What confirms this conjedure 
isy that if the dog approaches near enough to 
feize upon his prey, the bird inftantiy takes 
wing, and the hare fcampers away. It will 
certainly not be denied me, that it is fear which 
makes them fly. Such is the powerful elFed 
of inftin£t in every animal at the appearance 
of danger. But why do not the h^re and 
partridge at fight of the dog remain fixed and 
motionlefs with terror, like the ihrike and the 
moufe in prefence of the ferpent ? Why fliouid 
fear give to the former new ftrength, while the 
others die on the fpot, under all the increafing 
fymptoms of agony, and without the power of 
efcaping, as if retained by fome invincible 
force ? The rat does not remain ftationary 
upon the approach of the cat, but haftens away 
the moment he perceives her. May not then 
the look and prefence of a ferpent, and the na- 
ture of the corpufcles that emanate from its 
body, produce a very different effed from the 
emanation and look of the eat ?
