seven days. At the expiration of that time, the menstruum 
had acquired a beautiful green hue, and possessed, in a high 
degree, the properties of the plant. It was filtered and a por- 
tion evaporated to the consistence of an extract which consist- 
ed of two distinct substances, of which, one was yellow, oily 
or unctuous, bitterish, and pungent The other, black, resi- 
nous, slightly astringent. This was treated with sulphuric 
ether, which took up the coloring matter, (chlorophylle,) 
leaving the resinous portion undissolved. Alcohol dissolved 
this, and, upon a second evaporation, yielded a yellowish co- 
lored extract, excessively bitter and astringent to the taste, re- 
sinous to the touch, sticking with tenacity to the fingers. 
Water, when added to the tincture, gave it a milky appear- 
ance, owing to the separation of resin. Corrosive sublimate 
gave no indication of the presence of albumen. 
Experiment 3. — An ethereal tincture was made by mace 
rating half an ounce of the leaves in two ounces of sulphuric 
ether for seven days. The solution, when filtered, was clear, 
and of a beautiful green color. It possessed the pungent taste 
of the plant, with little of its odor : on evaporation it yielded 
asmall portion of fixedoil of a light green color, havingawarm, 
bitter taste, with the odor of the plant. The ethereal extract 
was of a dark yellow color, consisting of resinous, oily, and co- 
loring matters. < 
Experiment 4. — One ounce of the leaves was submitted 
to distillation with six ounces of water. During the process 
the odor was increased, and the liquid in the retort acquired a 
dirty white color. The quantity of leaves mentioned yielded 
more than half a drachm of pure oil. It was nearly white, lim- 
pid, possessing a very strong odor and pungent taste; analyzed 
by Dumas, oil of savine was found to be a compound of 10 
atoms carbon, 7.5, and 8 atoms hydrogen, 1.0. 
Experiment 5. — One hundred and fifty grains of the leaves 
were incinerated, leaving in the crucible twenty grains of gray- 
ish colored ashes. These were lixiviated with boiling water 
and filtered, a small portion of nitric acid was added to the
