This must be one of the earliest descriptions of the relatively new field
of ecology:

       "Ecology," as it is coming to be universally considered, is the
science of cause.  It is constantly asking "Why?" and not until can we can
answer "because," have we solved a problem in Ecology.  It is the capping
stone of the other branches of biological investigation.  Morphology
describes an organ or character; physiology shows us how it works and what
it does; ecology, building on these, tells how and why the character or
organ arose.  It, then, must be considered as more than the old Natural
History.  Although the value of the latter cannot be overestimated, more
must sooner or later be done."
