of the different islands wonderfully different. I give all the follow- 

 ing results on the high authority of my friend Dr. J. Hooker. I 

 may premise that I indiscriminately collected everything in flower 

 on the different islands, and fortunately kept my collections 

 separate. Too much confidenee, however, must not be placed in 

 the proportional results, as the small collections brought home by 

 some other naturalists, though in some respects confirming the 

 results, plainly show that much remains to be done in the botany 

 of this group: the Leguniinosfe, moreover, has as yet been only 

 approximately worked out : 



Hence we have the truly wonderful fact, that in James Island, of 

 the thirty-eight Galapageian plants, or those found in no other part 

 of the world, thirty are exclusively confined to this one island ; and 

 in Albemarle Island, of the twenty-six aboriginal Galapageian 

 plants, twenty-two are confined to this one island, that is, only four 

 are at present known to grow in the other islands of the archipelago ; 

 and so on, as shown in the above table, with the plants from 

 Chatham and Charles Islands. This fact will, perhaps, be rendered 

 even more striking, by giving a few illustrations : thus, Scalesia, 

 a remarkable arborescent genus of the Compositre, is confined to 

 the archipelago : it has six species : one from Chatham, one from 

 Albemarle, one from Charles Island, two from James Island, and 

 the sixth from one of the three latter islands, but it is not known 

 from which : not one of these six species grows on any two islands. 

 Again, Euphorbia, a mundane or widely distributed genus, has 

 here eight species, of which seven are confined to the archipelago, 

 and not one found on any two islands: Acalypha and Borreria,
