COFFEE AND CHICORY. 187 
When Coffee berries are roasted, some portion of the caffein is 
volatilized, there being a partial change of the sugar (from the 
berries) into caramel, with a general breaking-up of the aromatic 
volatile oil, and the albumin cells, causing extrication of gas. 
and steam, and the development of a very potential and volatile 
aromatic substance, methylamine. ;

With some persons strong Coffee will provoke an itching state 
of the skin. 
Caffein, the active nervine stimulant, and revivifier in Coffee, 
being practically synonymous with thein (that of tea), exercises 
its arousing effect more on the central nervous system, than on 
the heart, astea does. It removes the sense of fatigue, but is 
apt to induce sleeplessness. Per contra, for the insomnia of an 
agitated mind, or body, with a perpetual forcing of ideas on the 
former, as likewise for alcoholic sleeplessness, a strong infusion 
of the Coffee berry whilst raw, and unroasted, will prove very 
helpful; it must be freshly made with Mocha berries, and taken 
in doses of one tablespoonful at a time every half-hour, until sleep 
is induced. By Cuaffein the respiratory movements are made 
deeper, and more frequent, whilst the heart is indirectly stimu- 
lated to beat more forcibly. All experiments go to prove that 
Coffee-drinking leads to waste of tissue ; this berry (the same as 
tea) is not a muscle-making substance. Whilst the volatile oils of 
tea tend to dilate the superficial vessels of the skin, and to render 
it moist (cooling it by rapid evaporation in hot weather), Coffee 
has an opposite action. Tea-tasters are apt to become jumpy, 
starting on the slightest sudden noise, tremulous, liable to 
palpitation, sleeplessness, giddiness, and depression of spirits. 
Nevertheless, ‘* Tea,” said De Quincey, “ will always be the 
beverage of the intellectual.” It was the wakeful, exciting 
effect of Coffee berries, as observed by the Prior of a convent 
on goats, which first suggested their use as likely to keep the 
monks from falling asleep at their devotions. This influence of 
strong Coffee in producing excessive nervous stimulation, is a point 
well deserving the consideration of total abstainers nowadays. 
After a while it tends to check the appetite, and to prevent sleep, 
’ thereby doing harm to persons liable to neuralgic affections, who
