B will be richer and more varied than A. I call groups based
on these considerations Orders, or, if based on modifications
of the same sort of idea, Suborders. A given science with a
special name, a special journal, a special society, studying
one group of facts, whose members students understand
one another in a general way and naturally associate together,
forms what I call a Family, or [a?] smaller A subdivision of
it on the same principle, but taken more minutely, I
term a Subfamily. I can give no such definitions of genera
and species, not having carried my classification of the sciences
to these minutiae. For it is to be understood that I
have not first laid down fixed my definitions of branch, class,
order and family, and then adapted the classification
to those definitions, but on the contrary the classification
was first entirely formed with the exception of (except that the categories of
