ACROSS UNKNOWN SOUTH AMERICA 
From Lima I proceeded early the next morning to 
Callao, the port for Lima, a few kilometres farther, where 
at La Punta I touched the Pacific Ocean, thus ending 
my trans-continental journey from Rio de Janeiro, with 
its zigzags and deviations, 22,000 kilometres in length, or 
13,750 miles. 
I was already in better health when I reached Lima. 
The violent changes of climate from the hot valley of 
the Amazon to the snows of the Andes, and from there 
to the sea-coast, had had a beneficial effect upon me. The 
attack of beri-beri from which I had been suffering was 
gradually passing away, my right foot, by the time I 
reached Lima, having slowly got back almost to its normal 
size, although my toes were still atrophied. It is well 
known that there is no better cure for beri-beri than sea 
air.
