really the island which was thrown up in the second century 

 before Christ. Its three craters have evidently been formed at 

 very different periods (see Fig. 6, p. 58), and the newest of them 

 still contains one or two active fumaroles ; in the time of Spal- 

 lanzani it was clearly in a much more active state. Some of the 

 older lavas of Vulcanello were of basic composition. 



Such is the structure of Vulcano, which exhibits, as we have seen 

 in its various features clear evidences of a vast series of paroxysmal 

 eruptions, repeated, at not very distant intervals, during the whole 

 of the historical epoch. 



In our next chapter we shall describe Stromboli, a volcano offering 

 in its features, its modes of action, and its products, some remarkable 

 and very suggestive points of contrast with Vulcano.

Meteoric Irons found August, 1870. — Ovifak (or TJigfak) near 

 Godhavn, Kekertarssuak or Island of Disko, Greenland [Lat. 

 69° 19' 30" N. ; Long. 54° 1' 22" W.] 1 



The interesting story of the discovery of these enormous masses 

 by Prof. Nordenskjold is already known to the readers of this 

 Magazine through a translation of his original memoir. While ex- 

 ploring in Danish Greenland in 1870, his attention was directed to 

 the possibility that meteorites might be met with in Disko Island, 

 by the accidental discovery of a block of meteoric iron in some 

 ballast which had been taken in at the old whaling-station at Fortuna 

 Bay, near Godhavn, and he urged the Greenlanders to search the 

 district for masses of that metal. He proceeded to explore Omenak
