I'lMiiaiii in their liiiling places. However, we may assume that 

 sometimes a Ijat is, involuntarily, carried seawards; if so, it would, 

 almost invariably, be swept down b}^ the gale into the sea and 

 perish. We may again assume that it reaches an island; it would 

 probably arrive there in an exhausted or seriously mutilated 

 condition. We may suppose , once more , that it recovers ; but in 

 this case it must, in order to be the founder of a new colony, 

 have been accompanied by, or w^ithin a reasonable space of time 

 be followed by, an individual of the same species and the opposite 

 sex, Ijrought across the w^ater under similar, exceptionally success- 

 ful conditions. It appears safe to assume that this series of liappy 

 coincidences exceedingly rarely occur in nature; so rarely, indeed, 

 that it seems very unlikely that they should have any marked 

 influence on the geographical distribution of bats.
