the evening,'' says Mr Jameson, of the 9th 
March 1822, we re-embarked on board the Fifeshire Pac- 
ket, having determined to go to sea early the following 
morning. At 4 o'clock a. m. we accordingly got under- 
weigh, and proceeded down the harbour of Rio de Janeiro. 
At 7, the land-breeze having failed, and the tide setting 
against us, we were obliged to anchor abreast of Porto 
Fogo Bay. At 10, the sea-breeze having, as usual, com- 
menced, we again got under- weigh, and cleared the entrance 
of the harbour, after making several short tacks. Wind 
ESE. At 4 p. M. passed Round Island. Evening, light 
variable winds, occasionally calm." 
On the 20th, having reached Lat. @5° 23', and Long.
