soluble in alkalies, and yielded a whitish-yellow precipitate 
on the addition of acids. 
The original aqueous solution was again rendered alkaline 
and re-agitated with amylic alcohol. A small amount of a — 
slightly bitter yellowish extract was yielded, which failed to - 
afford any alkaloidal reactions, but reduced an alkaline copper 
solution after previous boiling with a dilute acid. 
In another experiment the powdered tubers were percolated 
with amylic alcohol, and the percolate agitated with cold water ; 
a colourless aqueous solution was obtained, which darkened 
during evaporation, leaving a yellowish residue. On the addi- 
tion of cold water to this extract a portion dissolved, while the 
remainder swelled up into a soft mass similar in appearance to 
recently precipitated partly dried aluminum hydrate. On heat- 
ing with water this dissolved, and on concentration, white — 
warty masses separated, which under the microscope were seen — 
to be destitute of crystalline structure. This principle is pro- 
bably allied to inulin, but as far as we are aware no observation 
has hitherto been recorded on the solubility of inulin in © 
~ amylic alcohol. 
The fresh tubers afforded no reaction for starch. Saccharine 
matter was present which reduced Fehling’s solution. A bitter 
principle, an easily oxidizable resin, and a resin acid were also 
present in addition to the principle which we have mentioned — 
as being probably allied to inulin.
