1st January 1771

[At Batavia]

In the P.M. stood over for the Sumatra Shore, having the wind at South-South-West, a fresh breeze, and the current in our favour; but this last shifted and set to the Eastward in the Evening, and obliged us to Anchor in 30 fathoms, under the Islands which lay off Verekens point, which point constitutes the narrowest part of the Straits of Sunda. Here we found the current set to the South-West the most part of the night; at 5 a.m. weigh'd with the wind at North-West, and stood to the South-West between the Island Thwart-the-way and Sumatra; the wind soon after coming to the westward we stood over for the Java Shore. At noon the South point of Peper Bay bore South-West by South, and Anger Point North-East 1/2 East, distant 2 Leagues; tacked and stood to the North-West.

Workd all night and today likewise. At night Anchord under a high Island call[d] in the draughts Cracatoa and by the Indians Pulo Racatta. I had been unacountably troubled with Musquitos ever since we left Batavia, and still imagin'd that they increasd instead of decreasing, although my opinion was universaly thought improbable; today however the mystery was discoverd, for on getting up water today, Dr Solander who happned to stand near the scuttle cask observd an infinite number of them in their water state in it, who as soon as the sun had a little effect upon the water began to come out in real Effective mosquetos incredibly fast.
