ON ITS EXTERIOR. VOLCANOES. 355 



in 1770 and 1793, and its height would appear to be 

 well-deserving of exact measurement, being estimated 

 at between 12,000 and 15,000 feet. The far lower peak 

 Sarytschew (4505 feet, according to Horner) in Mataua, 

 and the southernmost Japanese Kuriles, Urup, Jetorop 

 and Kunasiri have also shown themselves to be still very 

 active volcanoes. 



Next in our volcanic series follow Jezo and the three 

 great Islands of Japan, upon which the celebrated tra- 

 veller Herr von Siebold has kindly communicated to me 

 a very great and important notice, for employment in 

 the Cosmos. It will rectify and complete the accounts 

 taken from the great Japanese Encyclopedia in my 

 Fragmens de Greologie et de Climatologie Asiatiques 

 (t. 1, p. 217234), and Asie centrale (t. 11, p. 540 

 552). 



The large, and in its northern portion very square- 

 shaped, island of Jezo (41 J to 45^ lat), divided by the 

 Sangar or Tsugar Strait from Nippon, and by the Strait 

 of La Perouse from Krafto ("or Karafuto), bounds by its 

 north-easternmost cape the range of the Kuriles ; but not 

 far from the north-westernmost point, Cape Romanzow, 

 which advances a degree and a half further to the north 

 on the Strait of La Perouse, there is in 45 11' lat. the 

 volcanic Pic de Langle (5350 feet high), on the small 

 island of Eisiri. Jezo itself appears to be intersected 

 by a range of volcanoes running from Broughton's 

 southern Volcano bay towards the northern cape ; and 

 this is the more deserving of attention, because on 

 the narrow island of- Krafto, which may almost be 

 regarded as a continuation of Jezo, the naturalist of La 

 Perouse's expedition found in the Baie de Castries red
