The VEGETABLE SYSTEM. 
Upon thefe principles, uncertain as they may be, I {hall endeavour 
to bring the prefent fubjecft to a tryal. Its own Seeds are carefully 
fown in a place diftind and diftant from that where it now grows ; 
and in an experiment-bed deftined for fuch purpofes, the Flat Eryngo, 
and more than one Scabious, are placed in pairs clofe together, as if 
growing from one Root j to affift, if there be any fuch, the mixt im- 
pregnation. 
If in this place. Plants of this kind arife, I {hall judge it certain that 
it is Mulifh, and rifes from this accidental mixture j if its Seeds fown 
in diftant ground produce it, and none rife from the purpofely aflociated 
Plants, I own I {hall begin to judge it a fpecies from the creation, a Plant 
before unknown. In that cafe, it will deferve the place it holds here j 
and the rank of a new Genus muft belong to it : but I exceedingly 
doubt it ; for the Cup, though fo diftant from Scabious, feems true 
Eryngo ; and the harp’d end of the radical Leaf, together with its hol- 
low Footftalk, feem equally the Flat Eryngo j though its Flowers are 
plain and abfolute Scabious ; and the wingy Segments of that very Leaf, 
feem alfo to belong to a Plant of that kind.

The Head is globular ; the general Cup is compcfed of one 
range of filmy Segments, and is fhorter than the Flowers ; 
the feparate Flowers are cut into Segments, which turn
