 4.3. For various reasons it seems clear that these relations are only 

 apparent. In the first place, tiie divergence from the constant is in 

 many cases considerable. 



Moreover there are errors of experiment [cf. Meyer. Wied. Ann. 

 54, 415 (J895); Lohnstein. ibid. 54, 722 (1895) etc]. Under the 

 stress of criticism- (ibid, 53. 1070 (1894), 61, 2(57 (1897)), (^iincke 

 somewhat modified his views. 



It has now been found out that the specific coiiesion of elements 

 is a periodic function of their atomic weights.
