* Total weights (milligrams per 105 cigarettes) for indicated acids were as 

 follows: Turkish 48. 3; flue-cured, 30. 6; Maryland, 23. 7; burley. 16.5; 

 FBM blend, 20. 5; FBMT blend, 40. 5. See footnote below for blend com- 

 positions. Unidentified acids were calculated as n-caproic acid. 



**Relative amounts based on the levels in flue-cured cigarettes. Weights 

 were based on smoking 55 percent of cigarette length. F = flue-cured, 

 B = burley, M = Maryland, T = Turkish, FBM = blend (60 percent flue- 

 cured, 35 percent burley, 5 percent Maryland), FBMT = blend (40 per- 

 cent flue-cured, 35 percent burley, 5 percent Maryland, 20 percent 

 Turkish).
