INTHODUCTION. 
The powers of Nature, in the enchanting grandeur of the 
vegetation, which I witnessed during my travels in British 
Guiana, have become indelibly stamped upon my mind ; and 
since my return to Europe and my sojourn in Australia, by 
comparing the vegetation and scenery of these countries with 
those of tropical regions, they have become more and more 
vivid at the present time. Many years have elapsed since 
these lovely pictures unfolded themselves before my eyes ; 
and being still as fresh in my memory as if I had seen them 
but yesterday, I am induced, on the eve of my life, to offer 
a slight sketch of them to the lovers of Botany.
