The result of our observations gave the latitude of the place of the observatories 35º 17′ 46″.6 S., longitude 174º 8′ 22″.7 E.; the mean magnetic dip between the 23rd of August and 25th October, 59º 33′ S., the

Variation between 26th and 31st of August, 13º 33′ 52″.5 E.
1st and 30th of Sept. 13º 34′ 54″.6
1st and 23rd of Oct. 13º 38′ 45″.9
and first week of Nov. 13º 40′ 50″

showing a gradually increasing easterly variation.

The following are the results of our tidal observations:—a tide gauge was fixed at a convenient distance from the astronomical observatory, and the height of the tide was recorded every quarter of an hour, when near the time of high and low water, or every hour, at other times, day and night between the 14th of September and 19th of November, through a space therefore of two complete lunations, or five periods of full or change of the moon, viz.:—

It was full moon on the 15th September, at 5h 38m a.m.; the following high water occurred at 7h 30m, the amount of rise being then five feet nine inches; the highest and largest tide was the third
