ANALYSIS OF FLORIDA MOSS, TILLANDSIA USNEOIDES. 
An analysis of the so-called Florida Moss was made for the purpose 
- of learning whether in its composition it bore any resemblance to the 
Reindeer Moss, Cladonia rangiferina, which latter isin Sweden subjected 
to fermentation, with the production of alcohol. 
An analysis of the Florida Moss gave the following results for the 
dry plant:

The chlorophyll, xanthin, and oil included in the 3.6 per cent. men- 
_ tioned, consist of the green coloring matter of the plant mixed with a 
_ larger proportion of a yellow coloring matter (xanthin), which is noticed 
on crushing the fresh plant, and a little oil. 
__ Under wax is included that substance extracted by warm ether, solu- 
ble in hot alcchol, but insoluble in cold ether and alcohol. 
The resin from the ether extract is soluble in cold ether sparingly, 
freely in cold alcohol. It is a light-yellow brown, apparently somewhat 
crystalline body. It is very freely soluble in ammonia, with a brilliant 
_ brownish-ye:low color, and is precipitated by dilute hydrochloric acid. 
Another resin is found in the alcohol extract. It is darker in color 
_ than the former resin; is less soluble in alcohol and ammonia. It gives 
-with strong sulphuric acid a deep brown coloration. Both resins melt 
at low temperatures. 
The portion of the alcohol extract soluble in water has an acid reac- 
tion, and gives many of the reactions characteristic of tannic acid, but 
the precipitates are much more soluble than those of tannin; that with 
ammonio acetate of zine being easily soluble in water containing a few 
drops of ammonia. Iron salts do not give as deep a coloration as with 
tannin. No sugar could be detected in the plant. Starch, too, is absent, 
or only present in mere traces.
