These observations of Tschermak, taken in connection with 
the numerical relations which exist between atomic weights, 
give rise to very interesting results, and if the conclusions which 
he arrives at from his experiments should be confirmed, they 
cannot fail to exercise a very important influence on the progress 
of chemical science.
