These exceptions are all due to the boiling-point of propane, C 3 H 8 , being 

 too high ; see footnote to Table V. 



Relation 8 

 the halogen 



or 



The differences between the boiling-points^ of 

 of the alkyl compounds of the hydrocarbon 

 radicals of the seventh group , and those of the hydrocarbon 

 radicals of the other groups respectively, increase algebraically 

 from the chlorides to the bromides, and thence to the iodides {or 

 from the methides to the ethides, and thence to the propides, fyc). 

 (See Table VII.)
