The Progress of the Race 
[ 105 ] 
We shall pass over many intermediary 
species, wherein we may see the gradual 
lengthening of the tongue, enabling more 
nectar to be extracted from the cups of 
corollas, and the dawning formation and 
subsequent development of the appara- 
tus for collecting pollen, — hairs, tufts, 
brushes on the tibia, on the tarsus, and 
abdomen, — as also claws and mandibles 
becoming stronger, useful secretions being 
formed, and the genius that presides over 
the construction of dwellings seeking 
and finding extraordinary improvement 
in every direction. Such a study would 
need a whole volume. I will merely 
outline a chapter of it, less than a chapter, 
a page, which shall show how the hesitat- 
ing endeavours of the will to live and be 
happier result in the birth, development, 
and affirmation of social intelligence.
