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

species.—Statement of facts not referrible to any known law,—ex- 
amples of these.—Climate considered as a secondary influence on

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
