the violet end of the spectrum but showed no distinct bands. 
There was a feeble shading present in green and a very faint 
one at p; the latter became more distinct on the addition of 
caustic potash, which made the fluid redder. There was not 
enough pigment left for further examination. 
“ Actinometra from Banda.” Dr. Carpenter believes 
it was from this that Professor Moseley got his ante- 
donin. The solution had a faint yellowish-red tint, and 
showed two faint bands in the green which I took for those of 
antedonin. On evaporation in vacuo a dull red residue was 
left, this was soluble in spirit and gave the antedonin bands 
faintly. By the action of acids and alkalies it was evident 
that antedonin, somewhat altered by time, was present. No 
lipochrome could be detected in the residue. 
“A large Actinometra from Banda.” The solution was 
yellow, and on evaporation in vacuo left a violet-brown 
residue soluble in spirit, with a violet-red colour in deep layers 
and orange in thinner ones. It strongly absorbed (when 
dissolved in spirit) the violet end of the spectrum and showed 
no distinct bands. Hydrochloric acid made the colour paler, 
approaching to yellow, and no bands were seen. Caustic 
potash made the fluid redder and caused a faint shadow to 
appear at p, while a precipitate formed. The residue became 
yellow with nitric acid, and brown with sulphuric acid. 
‘““Actinometra paucicirra from Cape York.” The 
spirit solution was deep yellow, and somewhat reddish in a 
deep layer. On evaporation in vacuo it left a red residue 
containing crystals of chloride of sodium. The rectified 
spirit extract was reddish in deep, and yellow in thin layers, 
and this gave a faint antedonin spectrum. The residue was 
also soluble in chloroform, the solution strongly absorbing 
the violet end of the spectrum, and showing some faint bands 
in green. It was also partially soluble in ether, the solution 
showing a faint antedonin spectrum. MHydrochlorie acid 
changed the red colour to yellow; caustic soda intensified the 
colour, and then a feeble shading was seen close to p; ammonia 
produced the same change.
