N atural bodies are divided into three king*

Plants are compofed of three kinds of iTirels; 
vafa fuccofa^ which convey their juices; utricull^ 
which preferve them; and trachea^ which attract 
the air. 
The internal parts of a plant are, the cof'tex^ or

The external parts of a plant are, the root, which 
defcends,and draws nourilhment; the ftem, trunk; 
or flalk, which afcends ; the leaves, whofe office is 
to tranfpire and attract, like the lungs in animals; 
and the fructification, which opens and generates; 
confifting of flower and fruit. 
' The parts of the flower are, the calyx, corolla, 
Itamina, piftil, and receptacle. 
The calyx is the outer tegument or cover of the 
flower, proceeding from the outer bark of the 
plant, and often continuing till the fruit is ripe*
