COFFEA ARABICA. 195 
Description —Coffea arabica is an evergreen shrub, about 
sixteen feet in height, with a straight stem. The flowers are of 
a pale white; fragrant, but rapidly fading. The Jeaves are 
evergreen. ‘The fruit resembles a cherry, and grows in clus- 
ters under the axilla of the leaves, at first of a bright red, and 
afterwards becoming purple. In Arabia, the fruit, when ripe, 
is shaken from the tree and dried by the sun on mats. In the 
West Indies, the fruit is gathered by the hand and dried in 
the sun on platforms. One hundred bushels of fruit will 
yield on an average 1,000 pounds of Coffee, each plant 
yielding from one to two pounds. ‘There are thirty species 
known.

ing the mass from the sides of the vessel with a horn spatula. 
To the powder thus prepared add twelve drachms of alcohol, 
and put it into a glass vessel; let it remain eight days, and then 
separate the liquor from the sediment. Let this powder which 
remains at the bottom of the vessel be pressed free from all 
moisture, and placed in a glass retort with four ounces of dis- 
tilled water; boil till one ounce only remains, and mix the 
clarified liquor with the alcoholic tincture; eighty drops of 
alcohol is to be added to thirty drops of this mixture, and 
twice shaken. ‘This constitutes the first attenuation. 
This medicine is also prepared by trituration; one grain of 
the powder is triturated with one hundred grains of sugar of
