IN fpeaking of the Euphorbia Feplus, I had oceafion to take notice of the difficulty which Students in Bo- 

 tany find in inveitigating the Clafs and Order of this Genus, and endeavoured to make it eafier to them : in 

 this plant the parts of the fructification are fomewhat 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 

 to Warts for the purpofe of deftroying them ; but even in this cafe, great care mould be ufed in its applica- 

 tion. My, friend Mr, William Wavell lately informed me of a cafe which fell under his notice in the 

 Ifle of 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,,
