The greatest Variation I found in the Course of this Passage was in Lat^d. 36°:20′ S^o 39..00 E^t where it was 30°:34′W from that time to the Lat^d. 39°..40′ S Long^d. 50°..21′ E it continued little other than 27 degrees. In the Lat^d. 38°..50′ S^o. Long^d. 71°..38′ E^t it had altered to 19°..55′ W, and here it continued at, nearly untill in the Lat^d. 40°..56′ S^o Long^d 89°..54′ E^t, when it was 15°..24′ W. It now decreased to 6°..23′ W in the Lat^d. 44°:07′ S^o. Long^d. 122°:23′ E^t, and in the Long^d. 132°:35′ E^t Lat^d. 43°:56′ S^o I found 1°..38′ East, so that I( had passed the Line of no Variation which I was anxious to have determined; gbut the weather was too unfavorable. It is remarkable how it has changed in the course of 11 years, for when I was with Captⁿ. Cook we observed in the Lat^d. 43°..27′ S^o Longd. 141°:50′Et the Variation to be 1°..24′Et. so that the line of 1½ degree has changed it position 9°..15′ to the West. The Variation in Adventure Bay was 5°..53′ E^t and now I make it 8°..33′ E^t but this change is no more than is commonly supposed to take place.

The Time Keeper on the 21^st and 23^d. gave the Long^d of Pengwin Island 146°..46′:42″E^t which is 46′47″ too little; but this my observⁿ. on the 17^th. proved to me, and I infer that this error took place soon after my leaving the Cape, when the Therm^r. fell below 50° for its Rate was determined on a Medium when the Ther^r was about 65°, and I am sensible it is effected by any such changes,.

On the 26^th was the first day I could make any observations to establish the Time Keepers rate of going. I then found it to be 2′:52″,6 slow for Mean Time at Greenwich, and by four days corresponding observations, its Rate was 0″,83 loosing

p^r. 24 Hours, and Slow for mean Time at Greenwich on the 1^st. September 2′..50″,9, which is the Rate and error I leave this place with.

I have determined the Longitude of Pengwin Island by 19 sets of Lunar Observations on both sides of the Moon, which were all I could get, and I shall therefore finish my Remarks on that head by inserting the observations as they were taken of every kind

Each of the Variations is a mean of four sets of Azimuths by Two Compasses. The Long^ds. from the 11^th. of August are reduced to Pengwin Island by the Time Keeper, as those that are taken on board of the Ship. I found it High Water at the Change of the Moon at 49 Min^s past 6 in the Morning, and the rise and fall 2^F:8^In. Southerly Winds rises the Tide a foot or two higher if they are of any continuance., A Book of all my astronomical observations and another with the Account of the going of the Time Keeper belong to this Log, recourse to which may be had for farther particulars.
