TABLE E. 



25 cc. of the concentrated Lime-sulphur solution was diluted to 1000 cc, 

 by the addition of water after the following were added: 



The results in Experiment No. 5, as found in Table E. shows that at the 

 dilution of one to forty the largest loss of sulphur was when the 2 cc. of acid 

 Nico-sul and the acid Lead Arsenate were used together giving a loss of 27.37 

 percent of sulphur and a loss of only .36 of one percent of Calcium. The acid 

 Lead Arsenate gave a loss of 17.15 percent of sulphur and 1.98 percent of 

 Calcium, showing that the Lead Arsenate mixed with 2 cc. of acid Nico-sul 

 has a stronger reaction on a solution of Lime-sulphur diluted one to forty than 

 on a dilution of one to twenty than the Lead Arsenate alone, this alto shows 

 that an acid solution of Nicosul throws out of solution more sulphur from a so- 

 lution of one to forty dilution than a one to twenty dilution as also indicated 

 in Experiment three, where the dilute Lime-sulphur was treated alone with 

 2 cc. of acid Nico-sul. The amount of Calcium lost is very small in all of the 

 mixtures, showing that an excess of alkali has a tendency to throw it out 

 of solution as shown when alkaline Nico-fume is used. 



At the dilution of one to forty the results indicate that it is best to use as 

 near neutral solution of Nicotine compound that is obtainable and a neutral 

 Lead Arsenate when mixing them with a dilute Lime-sulphur solution. 



Experiment No. 6, was to determine the amount of Sulphur and Calcium 

 lost from the Lime-sulphur solution by the addition of exactly neutral or 

 slightly alkaline Lead Arsenate at the rate of four pounds to 100 gallons of the 

 solution containing 2 cc. of neutral or slightly alkaline Nicotine compound. 

 Dilution of the Lime-sulphur solution was one to forty.
