found my Pulfe much fuller and quicker $ 1 had an Appe- 
tite, and found my felf much more vigorous, and could 
bear Labour much better and eafier than before. 
But T did not rely on this Trial alone, imagining that 
this Alteration might proceed from the Pveft that we had 
that Day : But four Days after, finding myfelf fo fatigued 
and weary that I could fcarce fet on Horfe back, a Man- 
darin who was in company with us perceiving it, gave 
jne one of thefe Roots: I took half of it immediately, 
and an Hour after I was not the leaft fenfible of any

I would advife them not to make lefs than Ten Dofes 
of an Ounce, and not to take of it every Day, It is 
prepared in this manner ; The Root is to be cut into thin 
Slices, and put intoan Earthen Pot well glazed, and filled 
with about a quarter of a Pints of Water Paris Meafure 5 
The Pot mu ft be well covered, and fet to boyl over a 
gentle Fire $ and when theWater is confumed to the quan-
