TOBACCO PRODUCTS. 



Seven samples of tobacco products were collected. In four of the 

 samples the amounts of nicotine found were slightly below the guaran- 

 tees but the deficiences are so small as to be negligible.

SMUT REMEDIES. 



(Formaldehyde Solutions. ) 



Four samples of smut remedies representing three manufacturers were 

 collected. The active ingredient of all was found to be formaldehyde, 

 the amounts found varying from 17.78% to 30.00%. In every case other 

 substances had been added, such as coloring matter, tar oil, etc., pre- 

 sumably to, partially at least, disguise the formaldehyde. In no case 

 do the added ingredients enhance the fungicidal properties of the for- 

 maldehyde. Although there is a variation of nearly 100 per cent in the 

 amount of formaldehyde contained in these preparations, the directions 

 for their use are the same in every case. 



Formaldehyde, 40% strength, can be bought for |1.50 per gallon. 



LICE POWDERS. 



Eight samples of lice powders were collected and examined. Seven 

 were found to contain nicotine and naphtlialine (the last named being 

 the active constituent of moth balls) and six contained sulfur. Pyre- 

 thrum was present in three of the samples. 



All of these preparations would probably prove effective against lice 

 when used in a closed chamber but their efdcieucy would bo greatly re- 

 duced Avhen used in tlie open or in a large room.
