The 1-emarkable features of these analyses are 
tiie high projtortion of potanh and the absence 
of soda and silica. These characteristics together 
with tlie small quantities of chlorine and ferric 
o.xide are useful in enabling the analyst to 
decide whether or not a sample of coffee ha* 
been adulterated with chicory: — 
Dr. Winter Blyth furnishes the annexed table 
shewing the characteristic differences between the 
ash of cotfse and of chicory.
