 adulteration in America is made by Mr. C. Lewis Diehl to the 

 National Board of Health. His report gives tasteless, exhausted 

 aconite root ; arnica with but ten to fifty per cent, of the true 

 root ; hydrastis containing fifty per cent, beet root, serpentaria, san- 

 guinaria, and podophyllum. Sarsaparilla adulterated with nutgalls, 

 ipecac, matico stems, paper, bark, belladonna and digitalis hairs. 

 Whole peppers were acorns "turned " into small globes and dyed. 

 Peppercorns made of oil cake, clay, and cayenne. Pepper of light 

 weight macerated in brine to increase weight. Ground pepper — 

 pepper leaves, sage, rape, potato, spices, capsicum, guinea pep- 

 per, chicory, laurel leaves, olive stones, bone dust, dirt. 

 Quinine — finely picked cotton, salicene. Santonin — mica, boracic 

 acid twenty-two per cent., picric acid 100 per cent, (all picric acid, 

 no solution.) Ships biscuit enter into the following: cape aloes, 

 ipecac, opium and gamboge, twenty-five to fifty per cent. Scam-
