Judd and Milne (1905) | Victoria | No. P.T. | 22:00.7 | 22:08.9 | 24:44.5 | 18.0+ | Very large. Off paper over 2 min | |

The headers are the same as those in the Shide registers and stand for “preliminary tremors” (P.T.) and “large waves” (L.W.). Eight hours have been added to the times listed in Denison (1904) to correct to UTC time. The end times from Rosenthal (1907) are calculated from adding the duration (“Dauer”) to the start time (“V1”); his duration of 44 min for Victoria is presumably a typo, because it was 164 min (Denison, 1904; Reid, 1905).
