I have thus endeavoured to give you a 
fcetch of this infinite Clafs of vegetable pro- 
ductions, called Cryptogamia. By running 
your eye over the characters of the Orders 
and genera, you will-acquire a general know- 
ledge of the principles of this concealed part 
of the Linnaean Syftem ; and with this ge- 
neral knowledge you may reft fatisfied. If 
at any time, in future, you fhouid happen 
to have no better employment than micro- 
fcopical amyfements, the Cryptogamia will 
afford you much entertainment. And now, 
I fancy, we may fay with Virgil 
Clauditejam rivos, pueri>fat frata biberunt. 
Vale.
