standing the extreme analogy observable be- 

 tween the climates of Madeira and Teneriffe, 

 the plants of the first of these islands are gene- 

 rally less delicate to cultivate in Europe, than 

 the plants of Teneriffe. The cheiranthus longi- 

 folius of Orotava, for instance, freezes at Mont- 

 pellier, according to the observation of Mr. De- 

 candolle ; while the cheiranthus mutabilis of 

 Madeira passes the winter there in the open 

 ground. The heats of summer are of less con- 

 tinuance at Madeira, than at Teneriffe. 



The region of the vines exhibits, among it's 

 vegetable productions, eight kinds of arborescent 

 euphorbia • mesembrianthema, which are mul- 

 tiplied from the Cape of Good Hope to the Pe- 

 loponnesus; the cacalia kleinia, the dracsena, 

 and other plants, which in their naked and tor- 

 tuous trunks, in their succulent leaves, and their 

 tint of blueish green, exhibit features distinguish- 

 ing the vegetation of Africa. It is in this zone, 

 that the date tree, the plantain, the sugar cane, 

 the India fig, the arum colocasia, the root of 

 which furnishes the lower class with a nutritive 

 fecula, the olive tree, the fruit trees of Europe, 

 the vine, and corn are cultivated. The wheat 

 is reaped from the end of March to the begin- 

 ning of May : and the culture of the breadfruit 

 tree of Otaheite, that of the cinnamon tree of the 

 Moluccas, the coffee tree of Arabia, and the 

 cocoa tree of America, have been tried with
