(1) Double & Single Creation

as genera local & especially close & natural genera & even where genera are widely extended sections of the genera are generally local, analogy leads to conclusion to a position that species are local

Where same species occur which as above views imply occasional power of connection analagous species occur. Galapagos – when islds near greater chance of diffusion

(2) Alpine plants — temperate form in S hemisphere — Rheæ 2 species of.— allude to degree of separation necessary.

Inhabitants of islands mere number of species

(3) few & not well stocked mice everywhere Dew. Mammifers Frogs, Lizards — Land—shells — Bat & Seals

Relation of ancient geographical distribution with recent

Begin with this Geograph. Distrib most important because if species have descended from common parent, there must be now or have been propinquity — if created no such necessity — In many have been created for conditions alone, or some quite conjectural law.—
