subacetate of lead, and evaporate the filtered liquid, freed from 

 the lead by sulpliuret of hydrogen. The remnant, when ex- 

 tracted with alcohol, yields grape-sugai- to it, while the bitter 

 substance remains undissolved, and has to be dissolved in water 

 and precipitated with subacetate of lead. The deposit is decom- 

 posed under water with sulphuret of hydrogen, the solution, 

 separated fi-om the sulphide of lead, is required to ferment with 

 yeast, then dried and extracted with absolute alcohol. The alcohol 

 dissolves the Bitter and leaves after evaporating a syrup-like 

 liquid undermixed with colourless needles. — Neutral, non-niti'O- 

 genised, of very bitter, nauseoiis taste, dissolves in water, alcohol 

 and ether, reduces the alkaline solution of copper, after being boiled 

 with diluted sulphuric acid. 



Lycopodium-Kesin = Csg H32 O4. In Lycopodium Chamaecy- 

 ])arissias. Evaporate the mothei*-ley, left from the preparation of 

 the lycopodium-stearon (see this), treat the remnant with water 

 and boil the insoluble portion with a little soda-ley. After cooling, 

 this resin sejiarates and has to be recrystallized in boiling alcohol. — 

 Is insoluble in water, readily soluble in alcohol and in ether, fuses 

 at 170° under decomposition, is slightly soluble in cold alkalies, but 

 becomes decomposed by heating. 



Lycopollium-StearoilrrCso H30 O4. Found in Lycopodium 

 Chamfecyparissias. Separates from the alcoholic tincture of the herb 

 on evaporating, and is obtained by washing with cold alcohol and 

 water and by repeatedly dissolving in boiling alcohol, after cooling 

 as a jelly, which dries to a starch-like mass. — Amorphous, inodor- 

 ous and tasteless mass, fusing at 100°, burns on heating with an 

 odour of fat, has a neutral reaction, is insoluble in cold, slightly 

 soluble in Ijoiling water, in cold alcohol and in ether, abundantly 

 so in these liquids at boiling heat. 



UslCe BalSillU. Obtained by pressing the covering of the seed 

 (mace) of Myristica fragrans. Is of a rather thin fluidity, when 

 newly drawn, smells and tastes like mace, deposes on keeping a 

 white, granular substance.

[Mag'liolill. Bitter substance found by Wallace Procter in the 

 fruits of Magnolia umbrella. The M. crystallises from weak 

 alcohol in needles, and from strong alcohol or petroleum ether in 

 prisms; is less bitter than Lii-iodendrin, but produces a scratching 

 sensation in the throat; is almost insoluble in cold, slightly soluble 

 in boiling water, abundantly in alcohol, chloroform, sulphide of 

 carbon, and petroleum ether, especially when warm; is also easily 

 soluble in fat-oils, and less copiously in hot glycerin; has a 

 neutral reaction; evolves no ammonia with potash; is precipitated
