ANIMAL INTELLIGENCE. 31 
the mandate imposed upon their kind by a superior power, 
conveyed through a channel hitherto inscrutable, how could 
animals lower than dogs—hermit crabs, for example—be de- 
clared incapable of receiving similar supersensory stimulus ? 
In justice to Mr Myers’ memory, let it be said plainly that 
he never lent himself to any such hypothesis. On the con- 
trary, his whole treatise is confined to human personality, and, 
among human beings, only the elect, as it were; those who 
have begun to realise their latent privileges. He compares 
the process of supersensory development to the primitive 
stages of animal evolution, when the pigment spot on the 
skin of some rudimentary organism first became sensitised 
to light, and the creature received a novel sensation. 
The frontier between human beings and other creatures 
can only be drawn dogmatically and, so to speak, irrationally. 
Their characteristics and actions blend imperceptibly. Rather 
than accept Mr Myers’ exclusive doctrine, it is easier for minds 
accustomed to ponder upon the behaviour of animals to be 
frankly teleological, and to admit the probability of a Supreme 
Being and His invisible ministers communicating decrees 
through a medium of which none is more than dimly and 
speculatively conscious. 
Assuming a First Cause, instinctive activities in the lower 
animals may be regarded as the comparatively simple and 
intelligible results of forces initiated by him, acting unerringly 
in prescribed directions by means of co-ordinate organs 
modified by evolution. It is in accordance with the plan of 
nature that, in their performance of instinctive activities, 
certain insects should unconsciously take an indispensable part 
in the fertilisation of flowers specially adapted to take advan- 
tage of their visits. An extreme instance infinitely more he- 
wildering presents itself when the preservation of the race of 
both insect and plant depends upon the insect acting with as 
much circumspection and precision as could be shown by a 
human cultivator. Such is the well-known behaviour of the 
yucca moth (Pronuba vucasella). This insect haunts ex- 
clusively the flowers of the yucca, and, collecting pollen from 
one blossom, kneads it into a pellet which she carries by means 
of specially enlarged palps in her flight to another flower.
