but I regret to add this experiment has not received all the 
attention it deserved at the hands of naturalists. Practically 
nothing was done in the domain of zoology; before 1908 we 
find nothing beyond the remark of Stiorrer'), who in 1888 
conducted an inquiry into the formation of coral-reefs in the 
Krakatau-basin, to the effect that he had time left to look for 
land-animals. Therefore we are absolutely ignorant about the 
pioniers of the fauna. In the domain of botany we are fortuna- 
tely somewhat better informed. Trev?) visited the island in 
1886, i.e. three years after the disaster. We see therefore that 
we also lack information as to the first beginnings of the new 
flora, but still the results of Trevs’s visit are very important. 
Eleven years later he came to Krakatau a second time, accom- 
panied by some other naturalists among whom was Penzie °). 
The flora was then already comparatively rich. About what 
happened in the interval of years between these two visits one 
cannot do more than form a general notion, in the absence of 
ascertained facts. Ten years later again there landed on the 
island a party of botanists, among whom Ernst *); two years 
after that an expedition of the topographical survey service °), 
who had been joined by the first zoologist Mr. Jacosson *) and 
the botanist Mr. Backer’) (this was in 1908) and after another 
interval of eleven years myself came there together with the 
zoologists Messrs. Barrets and Sonrer. It was only on the last 
of all these expeditions that the summit was reached by a 
scientific investigator, so that our knowledge of ‘the part of the 
mountains upwards of 1200 ft. high is of very recent origin -
