5. ^ That to the Eaftward of the aforefaid places a Well* 
ward Variation begins , which reigns in the whole /Wi- 
^/2 Sea, and arifes to no left than Eighteen degrees under 
the Equator it felf> about the Meridian ot the Nor- 
thern part of Madagafcar and near the fame Meridian but 
in 39. degrees South Lat. it is found full 27 t degrees.- 
from thence Eafterly the Weft Variation decreafes^ fo as 
to be but little more than Eight degrees ztCape Comorin^ 
and than Three degrees upon the Coaftofy^z'^ ; and to 
be quite extin£t about the Molucca IJlands , as alfo a little

Dutch in 1642. 
6. That to the Eaftward of the Moluccas and Fan-M^

fo large extent s for that at the \^\zndl{ptterdam it is fenlib -

at the rate it decreafes, it may well befuppofed that a-

a Wefterly Variation begins.

Sr. ]6hn Norborough at Baldivia and at the Weft entrance of

that it cannot reafbnably extend many degrees into the 
South Sea from the Coaft of Peru zxii Chili , leaving room
