NIGER EXPEDITION. 137 
in the ill-fated Congo Expedition: when he again saw the 
Peak of Teneriffe, he welcomed it as a familiar object, and 
bade it adieu, rejoicing that a still more novel field of inquiry 
was opened to him, beyond this scene of his early exertions. 
A few short months terminated his life and hopes : like Vogel, 
he fell a victim to the dread fever of the pestilential coast of 
Africa: like him, too, he was a martyr in the cause of Bo- 
tanical Science. 
Possessed of so many and such touching associations, no 
naturalist-voyager can see the Fortunate Isles rising, one 
by one, on the horizon of the mighty Atlantic, without some 
feeling of melancholy, while reflecting on the fate of these his 
two predecessors, both most accomplished Naturalists of their 
age and day; and whose prospects and hopes were i in — | 
respect as bright, perhaps brighter, than his own. ` 
The excellent and beautiful work of Mr. Webb, on the 
Natural History of the Canaries, leaves little to be said, 
especially of their Botany ; and renders even an enumeration 
of the few species gathered by Vogel and the Botanist ofthe — — 
Antarctic Expedition unnecessary ; for they were all collected — — 
within a very few miles of Santa Cruz, during a very hurried ——— 
walk, and scarcely include a dozen kinds. This locality w = 
one of the most barren of the whole group, especially in the — 
immediate neighbourhood of the sea. The broad frontal of 
cliff and mountain, reaching upwards for severa 
feet above the town, and fore-shortened to 
seaward, presents a progressive increase of verdure from -
