It is true that at first sight this table seems to show many surprising 

 anomalies. Bindloe island was known to have forty-two species of 

 vascular plants at the time of Professor Robinson 's writing', and James, 

 which is one of the nearest to it, 153 ; fourteen species being common 

 to the tAvo. Charles, with 267 species, is much farther from Bindloe 

 than is James ; but Charles and Bindloe share twenty-five species. 

 But it is clear that the absolute numbers are misleading in this con- 

 nection, on account of the enormous difference between the numbers of 

 species, or known species, on the several islands. Charles, according 

 to these figures, is florally nearly twice as rich as James ; and, condi- 

 tions being reasonably equal, a greater number of its plants than of 

 those of James should therefore recur on Bindloe. As a matter of 

 fact, the proportion of fourteen James-Bindloe to twenty-five Charles- 

 Bindloe is less than that of 153 James to 267 Charles ; so that a greater 

 similarity between adjacent James and Bindloe than between distant 

 Charles and Bindloe could be more properly asserted than the contrary 

 finding of Professor Robinson.
