THE 



OF THE 

 GLOBE. 



CHANGES Fuogo, the Peak of Teneriffe, Volcano liland, in the Queen 



Charlotte Illands, the volcanos near New Guinea, and the Moluccas, 

 ^he Manillas, in Japan, Iceland, and the new difcevered illands 

 '.between Kamtchatka, and North America: of the latter fort k 

 Vefuvio, the volcanos in Kamtchatka and California : and the only 

 ones that fhould feem to make an exception, are the volcanos in the 

 Andes, in South America and Mexico; but even there, none is above 

 .1 CO miles in a ftraioht line, diftant from the fea. Thole which v/e 



found in To-foba, Ambrrym, and Tanna, belong to the firft clafs.

Thirdly, Volcanos are to be met with, only in countries containing 

 a o-ood many pyritical, fulphureous fubllances. The red ochre we 



-found on the lides of the hill in Tanna

ip 



ieen by us, looked exacftly like the remains of a pyrites -containing 

 fulphur and an iron earth, which had

ftulated and

in a ftrong 



fire. 



Thofe who have vilited the -neighbourhood of 

 x)ther volcanos, know very well that fuch red, ochreous flrata are 

 .very common in their neighbourhood. 



Fourthly, We found that after raiji,, the volcano in Tanna began 

 to rage and blaze more violently than before -, which feems to 

 imply, that the moillure. of .the rain, infinuatingitfelf into the inte- 



parts of the volcano, through 



d chinks

■meeting thefe pyritical ilrata, caufed a new fermentation, followed 

 i)y.new eruptions and violent explofions.
