JN JAVA. 



eorroding tropical mins of centuries are only now beginumg to 

 exhnme them. 



About the only piece of exposed strata in this part of Java, 

 I lielieve, lay \vlthin a few miles of my hut. Out of it I picked 

 fossil fmgments of vegetable stems, and of broken Ostma 

 and Pecim shells, closely resembling those still in the adjacent 

 fie^s, and showing that an elevation of some 200 to 300 feet had 

 taken place here at a recent period. That these subterranean 

 forces whose activity resulted in the varied physical changes 

 which West Java has experiencetl (such as the subsidence of 

 the Sunda Straits)* had not ceased, was brought home to me 

 with all the vivid and indescribable sensations that accompany 

 one's first experience of piwerfnl and unwonted phenomena. 



On the 28th of March, 1879, about eight o'clock in the even- 

 ing, while sitting under my verandah, a siidelen shiver and 

 a violent bumping wave pissed as it were through me and 

 irnder my feet, bewildering me, but affording me the ineradicable 

 experience of a violent earthquake. For some tlurty seconds 

 my hut and all its contents were lustily shaken, but otherwise 

 no harm was done. Some forty miles away, however, at the 

 base of the Gede volcano, the village of Tjanjoor was wrecked 

 and several lives lost amid the falling houses, while on the 

 following day volumes of smoke and iishes were emitted by the 

 mountain whose summit formed the background of my view. 



One of my most interesting discoveries here was a case of 

 mimicry in a s]dder, of the kind named alluring coloration 1^ 

 Mr, Wallace, The spider itself, to which I had given iho 

 provisional name of Thomism deeipiens, has proved interesting 

 as the type of a new genus, named Omiihomdoi'des by the 

 Rev. O P. Cambridge. The great interest attaching to this 

 find, however, is on account of its habits, I had been allured 

 into a vain chase after one of those large, stately flitting 

 butterflies (ffestia) through a thicket of prickly Pandanm 

 korridiis^ to the detriment of my apparel and the loss of my 

 temper, when on the bush that obstructed my farther pursuit 

 I obseiTed one of the Mesperiklw at rest on a lei\f on a bird's 

 dropping. I had often observed small Bines at rest on similar 

 spots on the ground, and have often wondered what the members 

 of such a refined and beautifully painted family as the Lym- 

 niilw could find to enjoy at footl seemingly so incongrnons fur
