The same remarks made in regard to Electric Vermin Exterminator 

 apply equally well to this compound. 



TOBACCO AND SULPHUR. 

 [Serial No. 19691.] 



Composition of Tobacco and Sulphur. 



Per cent. 



Moisture 4. 70 



Sulphur 36. 21 



Ash insoluble in hydrochloric acid : 19. 40 



Ash soluble in hydrochloric acid 14. 17 



Volatile matter, other than moisture and surphur 25. 52 



100 



The soluble ash consists of Ca, Mg, Fe, K, Na, P 2 O 6 , SO 3 , and CO 2 . 

 The sample evidently consists of sulphur and tobacco, but a larger 

 amount of sand is present than should be in a good sample of tobacco.

 [Serial No. 19692.] 



Composition of Tobacco and Sulphur. 



Per cent. 



Moisture 6. 57 



Sulphur 3.51 



Ash insoluble in hydrochloric acid 5. 17 



Ash soluble in hydrochloric acid 24. 08

100 



The soluble ash consists of Ca, Mg, K, Na, SO 3 , P 2 O 5 , and CO a . 

 Besides the above constituents, this sample is quite rich in potassium 

 nitrate. The sample, as claimed, evidently consists of sulphur and 

 tobacco, the latter of which is exceedingly rich in potassium nitrate, 

 which compound is excellent as a plant food.
