EXPERIMENT XXVI.

The result of the same trial with ipecacuanha was, that number 1 was

of a light brown colour, tasting highly of the ipecacuanha.

Number 2 was of a deep yellow, having the same disagreeable taste

of the lime complained of in the other tinctures, but that of the

ipecacuanha scarcely perceptible.

Number 3 produced a tincture of the colour of red port wine, strongly

flavoured with the ipecacuanha, though it had not so much of the

distinguishing sharpness of that root as number 1.
