dance of plant and animal life, and especially 

 the curious restrictions governing their range, 

 seemed, at first acquaintance, inexplicable. 

 The biologist now drew attention to the fact 

 that all the species represented were but curi^ 

 ously developed forms of types already known 

 to the scientific world. They had suffered but 

 little variation, though many had increased enor^ 

 mously in size. Furthermore, it was known 

 that such species could at one stage or another 

 in their life ^history be transferred for great dis- 

 tances by wind agency. Also many, even in 

 adult state, after remaining frozen for long 

 periods, maintained the power of reaniniation 

 when thawed out. ^ In the light of this inform 

 mation, it seemed most reasonable to suppose 

 that the invasion of plant and animal life had 

 come from warmer climes through the agency 

 of the anti'trade winds. ^ It was just about
