gainft the Gravel. We will fuppofe no more 
known concerning this Kind. A Perfon defirous 
of extending this ufeful Knowlege, finds that by 
the Tafte of the Root, which is infipid, and its 
mucilaginous Quality, he might have gueffed 
this to be its Virtue, from what he before knew 
of Medicine. The next Plant he meets, we will 
fuppofe is the common Mallow, and afterwards 
the little white flowered Mallow, which lies upon 
the Ground; he taftes the Roots of thefe, and 
he finds they are like the other: He will therefore

Roots, have been led to guefs that their Virtues

this, he might have been thence led to-tafte them, — 
and by that have been confirmed:in it: But he 
might be carried farther; he would find the fame
