Hi Mark,

Googling indicates source as "The History of Biological Theories" by 
Emanuel Radl (1930).  Radl contrasts Darwin and his followers with 
Leibniz' essentialism--

It was just this idea that Darwin and his followers combated in
using the same words. They asserted that between
isolated phenomena there are only unessential differences ;
in Nature things merge by insensible gradations one into
the other, just as, for instance, the hamlet becomes the
village, the village the little town, the large town, the city.
The distinction between these terms is merely a matter
of arithmetic, or of an arbitrary scale in the minds of those
who use them, s
