their number, fituation, and other circum-

clafjes and orders ; his families, or genera, 
are formed from all the parts of the bloffom 
or fructification ; his species, which are in- 
dividuals of the families, from the leaves of 
the plant ; the varieties, from any accidental 
circumftance of colour, tafte, or odour: the 
feeds of thefe varieties do not always produce 
plants fimilar to the parent, but frequently fuch 
as refemble that fpecies to which the parent 
belonged. Having given a fketch of the phi- . 
lofophy of the fyftem, the next thing to pro* 
ceed to is the examination of the different 
parts of a bloffom, or, according to Linneus, 
the fructification. Nor is a knowledge of any 
other than the engliih tongue neceffary to 
the acquirement of the language of botany: 
the latin pupil may know that the w r ord calyx 
fignifies cup, but that will not affift him in 
the knowledge of the various fpecies of ca- 
lyxes which he will have to retain in his me- 
mory; the common meaning of words is not

and cup and calyx require equal explanation
