time they lofe both one and the other from the Quan- 
tity of Sweat, until they become like the former In- 
habitants. Thefe Effects are moftobfervable in younger 
People } on the contrary, thofe who are farther ad- 
vanced in Life, when they go thither, preferve their 
former Appearance better, and enjoy fo good a State 
of Health, that they live commonly to more than eigh- 
ty Years of Age. 
As the Temperament of this Country is particu- 
lar, fo are fome of its Diftcmpers. Thefe may be 
conftder’d of two kinds ; viz. thofe Diftcmpers to 
which the Europeans newly arrived there are liable, 
and they only ; and thofe which are common to all 
Perfons, as well Criollos as Chapetones. t 
The Diftcmpers of the firft Ciafs are many, as the 
Refort of the Europeans there is very great. They 
are very dangerous, and often mortal. They fre- 
quently deftroy a great Part of the People, both 
Sailors and others, who arrive there from Europe. 
The Continuance of thefe Diftempers is very fhort 5 
they laft but three or four Days, in which time the 
Sick either die, or are out of Danger. The parti- 
cular Diftemper, to which they are mod liable, is 
very little known; though it takes its Rife in fome 
from taking Cold, in others from Indigeftion ; but 
from whichfocvcr of thefe, or from what other Caufe 
it takes its Rife, it becomes in the fhort time before- 
mention’d the Vomzto Erieto or black Vomit, which 
is what kills them ; it being very rare that thofe, who 
have it, efcape. It is obferved in fome, that their 
Delirium is fo violent, that they are obliged to be 
tied down in their Beds, that they may nor tear 
themfelves in Pieces ; and they often die raying with 
th.e greateft Degree of Agony. 6
