They are fo vifcid and acrimonious, that a Per- 
fon by reducing a Pound or two of either Sort in- 
to Powder, and not faking Care to avoid the finer 
Parts that are raifed out of the Mortar, is efredted 
in a fhort Time with a difficult Refpiration, Bleed- 
ing at the Nofe, fpitting of Blood, Inflammation 
and Swelling ot the Eyes, Face, or fometimes 
of the Throat, with the like Symptoms; which 
either of their own Accord, or by opening a Vein, 
difappear in a few Days. Further, being boiled 
in Water they give out a large Quantity of 
Mucilage, which is fo thick and tenacious, that 
a ftrong Expreffion is required to drain it through 
Linen. 
By Spirit of Wine, from eight Ounces of gray 
or Peruvain Ipecacuanha, were got ten Drajjrhms of 
Refin. From the fame Quantity of the Root, by 
common Water, were obtained three Ounces and a 
Half of a gum mous Extradl. The Powder re- 
maining, after the Gum and Refin had been ex- 
tradled from eight Ounces of the Root, weighed 
four Ounces. 
From eight Ounces of brown or Brafilian Ipeca- 
cuanha were got fix Drachms of Refin : and the 
fame Quantity of the Root yielded one Ounce and 
three Drachms of Gum. The Powder remaining, 
after the Gum and Refin had been extradled from 
eight Ounces of the Root, weighed fix Ounces. 
Hence it appears that the Quantity of adtive 
Principles, that is, of Refin and Gum, is greater 
in the gray Sort than in the brown. 
The refinous Extract is ftrongly emetick. The 
gummous Extradl likewife vomits, though but very 
little ; yet it fometimes cures Dyfenteries, whilft 
the Refin, on the other Hand, does not. The Pow- 
der remaining after the Ext radii on of the Gum and 
Refi n is altogether inert ; fince it neither vomits,
