21st - 22nd July 1833

Maldonado
Gained the harbour of Maldonado, the weather being very light & hazy detained us. We had a strong instance of the dangerous navigation of the Plata; having good Latitude observations & having only left port for two days we were nearly 40 miles out of our reckoning. This was entirely owing to a strong current, of which there was no means of previously ascertaining the existence.
