The same remark may Ik? made of the goose, which has only 

 been recently introduced into Bogota. The peacock, guinea-fowl, 

 and pigeon, have undergone no change. The conclusions drawn 

 from the report are, 1*^, That every animal, Hke man, requires 

 time to accustom itself to climate ; and, 2J/^, that domestic ani- 

 mals, when left to themselves, have a great tendency towards the 

 organization of those of the same species in a wild state; and 

 that a very short time only is necessary to produce that trans- 

 formation. 



BOTANY. 



14. Hybrids produced by Species of Rlwdodendron, Jzalea, 

 and Rhodor a fertilizing ecu:h other. — It has been found that the 

 flowers of different species of the genera Rhododendron, Azalea, 

 and Rhodora, fertilize each other, and produce hybrids of end- 

 less variety ; rendering it doubtful whether the generic distinc- 

 tions be well founded. This has occurred at the Earl of Liver- 

 poofs collection of American plants at Coombe Wood ; and still 

 more remarkably, at the Earl of Caernarvon's extensive collection 

 at High Clerc. Mr Gowen, who has paid particular attention 

 to hybrid productions, mentions, that at High Clerc, he saw 

 above a hundred seedling hybrids raised from different varieties 

 of Azalea viscosa and nudijhra, which had been fertilized with 

 the pollen of Rhododendrons intermediate between R, ponticum 

 and R. catawbiense. These hybrids are evergreen in ordinary 

 winters, like the Rhododendrons ; but, in severe frost, shew a 

 tendency to shed their leaves, like the Azaleas. 



ANTHHOPOLOGY. 



15. Craniohgy. — It is in the brain, then, that we are tempt- 

 ed to place the seat of reason ; and aS it appears that the human 

 brain excels that of the monkey, by the number and intricacy of 

 its folds and convolutions, so should we analogically be led to 

 suppose, that the difference in mental endowments, between one 

 man and another, may be connected with a greater amplitude of 

 the surface of the brain, in those who are the most highly gifled. 

 Then it is certain that the skull is formed after the brsdn, and 

 moulded upon it, and that very moderate attention will enable 

 an anatomist, for the most part, to distinguish those prominences
