By the side of our drawings, it is desirable to 

 put a sketch of the general appearance of the whole 

 individual ; and if it be a tree, to add a scale of the 

 size. 



In our descriptions, if we be accustomed to the 

 technical details of botany, we should be careful 

 to note those particulars which are not easily seen 

 in an herbarium, such as the exact insertion of the 

 parts of the flower and the fruit, especially when 

 the organs are very small ; the precise construction 

 of the grain, &c. 



In climbing plants, when any species be found 

 which resemble European, it is particularly^ neces- 

 sary to notice which way they twist round their 

 support ; the traveller, supposing himself in the 

 place of the support, his face turned tov/ards the 

 south pole, to ascertain if they ascend from right 

 to left, or from left to right.
