This alkaloid was doubtless the one which was found associated 4 
with the colouring principle, and to which reference has already © 
been made. e colouring principle gave similar reactions — 
to the one already described. The original aqueous alkalin 
solution left after agitation with chloroform was filtered, an 
then agitated with amylicalcohol. The amylic alcohol solutio 
was of a deep claret colour: it was agitated with dilu 
hydrochloric acid. The amylic alcohol on evaporation left 
’ light green: varrish-like residue insoluble in water or in dilut 
hydrochloric acid. The addition of ammonia to the soli 
extract dissolved a portion, the solution being of a damson-red_ 
colour. The residueinsoluble in ammonia was of a dirty brown 
hae. The addition of acids to the ammoniacal solution p 
cipitated pale greenish flocks. 
The hydrochloric acid solution of the amylic alcohol extr: ot 
was of a deep brown colour, carbonate of soda was add 
which precipitated brown flocks, and the solution agitate 
with amylic alcohol. The amylic alcohol became of a dam 
red colour. On evaporation a damson coloured varnish-li 
residue was left, ee soluble in water acidif 
a trace of a was Be, The addition of alkalies occa 
sioned the precipitation of white flocks: with the ordina 
- alkaloidal re-agents precipitates were obtained. The princip 
possessed the properties of an alkaloid, but appeared to differ 
from the first one described in bemg more easily soluble i i 
dilute acids, and in possessing a much more marked bitter tas 
accompanied by harshness. The amount isolated was far t ) 
small to admit of any examination of its platinum salt. 
The colouring principles which have been isolated by the 
action of amylic alcohol were probably similar to tho 
obtained earlier in the analysis by the action of chloroform, 
&c. The aqueous residue left after the action of amylic alcohc 
was not farther examined.
