probable that that plant had been ufed in its (lead. 
Upon getting a fpecimen, it appeared that this had 
been indeed the cafe ; as alfo, upon farther enquiry, 
that it was the juice of the root only, and not of 
the leaves and ftalks, that had been adminiftered. I 
might here obferve, that the expreffion from the 
root is not to be depended upon after the plant is 
advanced towards its flowering Rate, as the root 
then becomes light, fpungy, and almoft deditute of 
juice. 
If you judge this cafe not improper to be laid 
before the Royal Society, you will do me the honour 
of prefenting it. Mr. H n himfelf is fo much 
convinced of the efficacy of the medicine, that he is 
defirous of its being: known to the world. 
I do not enter into any reafoning on this occur- 
rence ; 1 relate it only as a fadl, and defire it may 
have no more weight than every judicious phyfician 
knows is due to a fingle infiance. How far it may 
be proper to give this juice a farther trial, I will 
not take upon me to determine ; but muft, as an 
encouragement to any who may chufe to venture 
upon it, inform them, that it has not on all perfons 
lo much power in producing naufea and ficknefs, as 
in the cafe here before us. 1 am,
