of spontaneous motion. Spheres of distribution depending on climatic
relations. Regions of vegetation, and classification of the genera of
animals. Isolated and social living plants and animals. The character of
flora and fauna is not determined so much by the predominance of separate
families, in certain parallels of latitude, as by the highly complicated
relations of the association of many families, and the relative numerical
value of their species. The forms of natural families which increase or
decrease from the equator to the poles. Investigations into the numerical
relation existing in different districts of the earth between each one of
the large families to the whole mass of phanerogamia -- p. 346-351. The
human race considered according to its physical gradations, and the
geographical distribution of its simultaneously occurring types. Races and
varieties. All races of men are forms of one single species. Unity of the
human race. Languages considered as the intellectual creations of mankind,
or as portions of the history of mental activity, manifest a character of
nationality, although certain historical occurrences have been the means of
diffusing idioms of the same family of languages among nations of wholly
different descent -- p. 351-359.
