TABLE A. 



100 cc of the Lime-sulphur solution was diluted to 1000 cc by the addi- 

 tion of water after the following were added: 



The result in experiment number one, as found in the Table, A shows 

 that at the dilution of one to ten a very small percentage of calcium is thrown 

 out of solution by mixing any of the Nicotine compounds with Lime-sulphur 

 solution and the acid Nicotine thrown out almost three times as much calcium 

 out of solution as the Nico-fume which is alkaline, and twenty four times as 

 much as with the neutral ''Nico-sul" compound. The loss of calcium in any 

 of the mixtures are not large and hardly to be considered. As to the sulphur 

 there is more than three percent more of sulphur thrown out of the solution 

 by the use of acid "Nico-sul" compound than with the alkaline solution of 

 Nico-fume and a little more than two percent more sulphur is lost by the use 

 of acid "Nico-sul,, compound than with the neutral "Nico-sul" solution. The 

 alkaline "Nico-fume" solution throws out of solution more calcium than the 

 neutral "Nico-sul" solution due to the alkaline substance replacing some of the 

 lime. With the sulphur lost it is just the opposite as the lime-sulphur solution 

 is alkaline and the alkaline "Nico-fume" helps to hold it in solution. At this 

 dilution the results show that it is best to use neutral or slihtly alkaline Nico- 

 tine and not the acid Nicotine solutions, as acid "Nico-sul" compounds with 

 the lime-sulphur solutions. The use of Rextract is not advisiable as it is a 

 mixture of Lime-sulphur solution and Nicotine compound and contains a large 

 quantity of hydrogen sulphide, besides the difficulty of obtaining a uniform
