Relation 1. (a) If the elements be arranged in the order 

 of their atomic weights, then the boiling-points of their alkyl 

 compounds rise and fall periodically, (b) Under similar con- 

 ditions, the specific gravities diminish up to the middle member 

 and then increase to the last member of each series. (See Table II.) 



The exceptions to this rule, in the case of the boiling-points, 

 occur either at or near the maxima or minima (i. e. at the
