INTRODUCTION.

In the feven preceding inrtaneef, the Cups are figured alone, fepa- 
rated from the Common Head, and diverted of their Flowers j that 
the dirtinCt form of each might be feen, without the incumbrance or 
confufion of anv other part. But that it may be alfo feen how they 
appear in complex Nature, they are reprefented in the fucceedir.g Fi- 
gures with the Flowers in them. 
Fig. 1 6. gives an example of the Even Cup in the Tea fell, with its 
Flower. 
Fig. 17. gives an example of the Folded Cup in the Thrift , with its 
Flower. 
Fig. 18. of the Simple Cup , in the Globewort, with its Flower. 
Fig. 19. of the Double Cup , in the Scabious, with its Flower. 
Fig. 20. of the Til'd Cup, in the Globe Thirtle, with its Flower. 
Fig. 21. of the One-leaf d Cup , in theBirdweed, with its Flower. 
Fig. 22. of the many-leaf'd Cup, in the Thread wort, with its Flower. 
Under one or other of thefe Orders, may be arranged all the Ag- 
gregate Plants ; for Nature, fo far as yet known, has given no other 
differences in their particular Cups : yet it fhould feem, that between the 
Plants of the fixth and feventh Order, there will be atfome time found 
whole Genera of intermediate Characters for it is not ufual with Na- 
ture to leave chafms in her works, or to pafs over great deficiencies 
in number of the parts. We are here, though in an artificial fyftem, 
tracing her fteps, fo far as may be in fuch fetters, with an awful 
reverence. 
With refpeCt to the five firrt Orders, their differences arife in a way 
perfectly natural, and the four fucceeding may be deduced plainly from 
the firrt, by a meafured Scale, in the fame method of gradual divifior, 
by which Plants themfelves, in the true fcale of nature, afeend above 
one another by a meafured addition of parts. The folded Cup is no 
more than the even one, with an exuberant edge ; the fimple Cup 
is only the folded one, cut down between the Plaits ; the double Cup 
is the fimple one, throwing off its outer Rind toward the bafe, in one 
feries and the til’d Cup is only the double one, with Films fplit off 
outward, in feveral feries.
