This substance evidently consists of partially air-slaked lime, treated 

 with some crude carbolic acid, and colored with a pink dyestuff. It 

 does not possess much power as an insecticide, since even pure carbo- 

 late of lime is not particularly effective in this direction. Lime also 

 has only weak insecticidal properties.

The portion of ash soluble in hydrochloric acid consists of large 

 amounts of Fe, Al, Ca, and CO 2 , some Mj', and small amounts of SO 3 

 and P 2 O 5 . This sample appears -to consist of small amounts of carbo- 

 late of lime and tobacco and large amounts of lime, calcium carbonate, 

 and probably cla}'. While the lime and carbolatc of lime possess weak 

 insecticidal properties, and the tobacco is of some value, the compound 

 as a whole appeai-s to have very little value. The price (25 cents per 

 box) is also excessive.
