The most important term in ∂2f1∂c12 is 2R [(c1−γ1)+(c1−γ2)+(c1−γ3)]. It is, therefore, of the first order of small quantities at points on tho node-locus. Hence, at points on the node-locus, f2/∂2f1∂c1 and f2/(∂2f1∂c1)2 both vanish, but f2/(∂2f1∂c1)3 is finite.” p. 225, lines 10-13, for f1 (alone) in numerator, outside the [ ], read f2. p. 225, line 14, for single f1 read f2 (three times); after this line (14) add— "The last term has been shown to be finite.” Dele p. 226 and lines 1, 2 of p. 227. p. 227, line 15, follow with " (This point is specially considored in Example 4 below.)” and dele ( ) below. p. 227, line 16, for single f1, read f2. © Oxford University Press ERRATA nationallicence Proceedings of the London Mathematical Society Oxford University Press s1-22/1(1890-11), 481-482 0024-6115 s1-22:1<481 1890 s1-22 plms https://doi.org/10.1112/plms/s1-22.1.481-s text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1112/plms/s1-22.1.481-s text/html Onlinezugriff via DOI NATIONALLICENCE 773 0- Proceedings of the London Mathematical Society Oxford University Press s1-22/1(1890-11), 481-482 0024-6115 s1-22:1<481 1890 s1-22 plms Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence SWISSBIB 375730451 BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
