IN (peaking of the _ Euphorbia Peplus, I had occadon to take notice of the difficulty which Students in Bo- 
tany find in invefligating the Clafs and Order of this Genus, and endeavoured to make it eafier to them : in 
this plant the parts of the fructification are (bmewhat larger ; and it differs from the other Spurges in having 
its leaves finely ferrated. In its acrimonious quality it is inferior to none ; hence it has often been applied 
fo Warts for the purpofe of deftroying them ; but even in this cafe, great care (hould be ufed in its applica- 
tion. My friend Mr. William Wavell lately informed me of a cafe which fell under his notice in the 
°f Wight, where from the application of the juice of this Spurge to fome Warts near the eye of a little 
girl, the whole face became inflamed to a very great degree. 
It is very common in gardens and cultivated ground, flowering in Autumn.
