Cl=43.20%. 43.45%. 



Methiodide. 



Tlie base was heated with excess CH.,I in a sealed tube at 100°. 

 The tube was broken and the excess CH3I evaporated. A recrys- 

 tallization from alcohol gave red needles of the product.

Platinum Double Salt of Dichlorparatoluquinoline. 



The platinum double salt separates out when platinum chloride 

 is added to the HCl solution of the base. 



Platinum Determination. 



.1543 grms. of substance dried at 100° and ignited gave .0359 grras.

 Action of SjBr.^ on Pakatoluquinoline. 



Ten grams of paratoluquinoline were mixed with thirty grams 

 SjBrj and heated several hours in the oil bath at 120°. No sulphur 

 base is here formed. The product of the reaction was treated with 

 concentrated HCl, and the solution thus obtained was distilled with 

 superheated steam. A poor yield of a monobromparatoluquinoline
