John Lort Stokes (1812-1885), naval officer, served on all three voyages of the Beagle; he was mate and Assistant Surveyor on the second voyage (with Darwin) and commanded at the end of the third. He returned to England in September 1843 after eighteen years' service in the Beagle.

Since this was written, I have consulted my friend, Mr. Darwin, who has kindly examined a specimen I brought away. He pronounces it "a superficial highly ferrugineous sandstone, with concretionary veins and aggregations."1 The reader should, however, consult Mr. Darwin's work on the 'Geology of Volcanic Islands,' p. 143.

1 The specimen was collected on 7 February, when the Beagle was anchored 1 1/2 miles from Port Swan, Western Australia (see pp. 95 and 101).

"Are there masses of coral or beds of shells some yards above high water mark, on the coast fronting the barrier reef?"1
