—A correspondent of Nature, who has evidently 
had a good opportunity to study the results of the 
Krakatoa eruption, and has made soundings in the 
neighborhood, writes, that instead of the sixteen new 
voleanoes which were at first reported, and the total 
destruction of Krakatoa, there is still a considerable 
portion of the island, and that the greater part of the 
destruction seems to have come from the wave pro- 
duced by the eruption and the fall of the masses of 
material which were thrown from the northern por- 
tion of the island. Krakatoa at its northern end now 
rises in a steep wall eight hundred metres high; and, 
Krakatoa 
before the Eruptioa.

where was once land, soundings of three hundred

have been deposited a few miles to the north, as shown 
in the map, by the new islands of Steers and Calmejar, 
and the shoals to the north of Lang Island, which 
seems to have been about on the line between the 
upheaval and downfall, and has not been changed 
materially in size. All the islands are covered with 
ashes; the destruction of life having been nearly 
complete, even in Sebuku, the first patches of green 
showing themselves on the small islands farther north.

history section of the British museum, Although 
about eighty years of age, he is still vigorous, and 
reads papers before the learned societies at nearly 
every meeting. The establishment of a natural- 
history museum was long an object for which he 
toiled. Over twenty years ago he published an ad- 
dress ‘on a national museum of natural history,’ in 
which he stated his view relative to the need for, and 
the proper organization of, such an institution. ‘The 
new museum is in a large degree the result of his 
labor.
