geographical situation and distribution of animals are quite un¬ 
known.—Two sets of laws in operation on the geography of animals 
primary and secondary.—Primary law of dispersion of the animal 
kingdom from the equator to the poles,—this influence of heat elu¬ 
cidated by the distribution of animals on continental mountains.— 
The whole earth inhabited.—The law of arrangement of the indi¬

mary laws. The last primary law applicable to tribes as well as 
species.—Statement of facts not referrible to any known law,—ex¬ 
amples of these.—Climate considered as a secondary influence on 
animal dispersion.—Geographical position and arrangement of 
a country considered as a secondary law,—connected influences of 
these two laws on our Fauna.—General assertions relative to our 
climate,—its effects on migration of birds,—further considerations re - 
relative to our climate.—Influences of human operations on animal 
geography.—Food considered as an influence on habitats,—“ polity 
of nature,”—relative effects of food and weather on the migration of 
birds,—other effects of food.—Anomalous circumstance of habitats 
in some animals.—Hostility of man considered, the advantages and 
disadvantages of his attacks on animals.—Plans intended to be pur¬

Zoology of Dartmoor. —Physical incapacity of the Moor to sup¬ 
port an extensive Fauna.—Ancient Fauna of this spot when a 
forest.—Considerations relative to the quadrupeds of the Moor, and
