Adulterations as for Cassia cinnamon. There are several com- 

 mercial varieties of cinnamon which are botanically related to the 

 saigon variety and they constitute the better grades of commercial 

 cinnamons. The very best grades used by the Chinese in their medical 

 practices do not reach the general market because of the high price 

 placed upon them, which is from $15.00 to $75.00 per pound, and even 

 more. The Chinese quality test is based upon the thickness of the oil 

 bearing layer of the bark.
