Rydberg favours the former view, but he does not attempt to obtain any very close approximation between the observed and calculated values of the frequencies.
According to an important law discovered by Rydberg and shortly afterwards independently by the writer, the frequency of the common root of the two branches is obtained by subtracting the frequency of the root of the trunk from that of its least refrangible and strongest member.
Rydberg discovered a second relationship, which, however, involving the assumed equation connecting the different lines, cannot be tested directly as long as these equations are only approximate.

It will therefore be best in this brief sketch to say that the leader of the elder school was Viktor Rydberg (q.v.; 1828-1895) and that he was ably supported by Carl Snoilsky (q.v.; 1841-1 9 04) who at the beginning of the 20th century was the principal living poet of the bygone generation in Sweden.
