Errata and Addenda

Page 144. The results, in this paper, stated for surfaces of revolution should be deleted, as the differential equations there given are obeyed, not by H and E , as stated, but by dH/dp and dE/dp . Page 103, table, last line but one, column of ½ e , for “32,” read “16.” Page 104, result (117), for “ n 4 ,” read “16 n 4 .” Page 105, table, last line, for “ e =,” read ”2 e =.” Page 109, table, for “5,576,681,” read “5,576,881.” Page 117, line 5 up, for “556,313,” read “556,513.” Page 118, line of 155,377, column ofp ‐ 1 ξ , for “8.9.23,” read “8.9.13.” Page 119, column of p , for “1,554,713,” read “1,554,913.” Page 122, table. Remove the whole line of p = 23,057 to left‐hand side of table, with the correction “ b = 16,” instead of “256.” Page 166, line 2, equation (490), read “ σ =( 1 + a ) 2 ( 1 + a + 2 a 2 ‐ 2 a 3 )( 1 ‐ a ) 3( 1 ‐ a ‐ a 2 ) 3.” Page 168, equation (519), read “ Z 2 = z 2 ‐( 51 )+ 2( 15 )6 z + 1 3 + 2( 85 )15.” Page 178, equation (598), read “=− q 3 +3 q 2 +6 q +13−3√Q.” Page 427, line 4, read “ + y ′′λ ′ 2.” Page 429, equation (186), read “ c = b 3 , c 4 , c 5 , b 4 , 0, ….” Page 475, equation (480), read “ c 22 = 1 c ( θ + 2 5 ω )”. Page 487, 3rd line from bottom, for “(2,2)” read “(2,3).” Page 488, line 19, after “the cells on ( p , q ),” insert “( p , q being prime to each other).” Page 489, line 23, for “10th” read “5th.” Page 490, 2nd line, for “ D ” read “E.” Page 494, line 6, after “line (2,3),” insert “2, 3 being factors of 6, (2,3), (3,2) will be called factor paths .” Page 494, bottom row of Diagram K, read “λ 4 ” for “λ,” in last cell but one. Page 495, line 4, for “each appears,” read “each pair appears.” Page 496, line 10, after “two rows of 12 cells,” insert “the symbols in.” Page 505, last line, for “0,24,” &c., read “0,30, the 0,0 cell of the upper square”; and add: —“When n = 24, the cells along 2,3 and 3,2 measured from 0,0 are different from those of 2,3 and 3,2 traced inward from the cell 0,24; but those of 4,3 and 3,4 from 0,0 and those traced inward from 0,24 are identical. When n = 18, the cells 3,2 and 2,3 from 0,0 are identical with those of 3,4 and 4,3 traced inward from 0,18; and the cells of 2,3 and 3,2 are identical with those of 4,3 and 3,4 traced inward from 0,18.” Page 590, equation (268), transpose “cos −1 ” and “sin −1 .” Page 601, equation (308), transpose “cos −1 ” and “sin −1 .”
