Rh and eemed to be going nearer to its original Portmouth rate. The reult of a fortnight's obervations proved it to be gaining at the rate of 6″ per day; and admitting the longitude to be right as acertained by our obervations, it was, at noon on the 9th of October, fat of mean time at Greenwich 26′ 14″: and as it was manifet; on our arrival and during our reidence at the Cape, that Kendall's chronometer was gaining materially on its Portmouth rate, I have, in reducing the obervations taken prior to our arrival in King George the Third's Sound, adopted a mean rate, which I trut will render the reult of the everal obervations liable to little error.

The variation of the magnetic needle on board whilt at anchor, by two compaes, differed from 3° 55′ to 7° 11″. The mean reult of 12 ets hewed 5° 20′ wetwardly variation.

Our obervations with regard to the tides were rather indeciive, as their fluctuation in the found eemed to be greatly influenced by the force and direction of the wind; our lat viit however to Oyter Harbour afforded an opportunity of noticing, that the rie and fall appeared on that day to be about four feet, and that it was high water 3$h$ 42′ after the moon paed the meridian. Whilt on the coat the veels were contantly found to be further advanced, than what the run of the log intimated ; but whether this was occaioned by errors in this practice, or by a current continually preing eatward along the coat, we had no poitive means of dicovering; though, from our concluions at the time, the latter hould eem to be the cae, as the log was not only ued with much circumpection, but the line was frequently remeaured, and always found according to its due proportions.
