I believe that a careful consideration of the structure of a species, and of the peculiar physical and organic conditions by which it is surrounded, or has been surrounded in past ages, will often, as in this case, throw much light on the origin of its habits and instincts.

These again, combined with changes in external conditions, react upon structure, and by means of "variation" and "natural selection", both are kept in harmony.
My friends remained three days, and got plenty of wild pigs and two Anoas, but the latter were much injured by the dogs, and I could only preserve the heads.

A grand hunt which we attempted on the third day failed, owing to bad management in driving in the game, and we waited for five hours perched on platforms in trees without getting a shot, although we had been assured that pigs, Babirusas, and Anoas would rush past us in dozens.

I myself, with two men, stayed three days longer to get more specimens of the Maleos, and succeeded in preserving twenty-six very fine ones--the flesh and eggs of which supplied us with abundance of good food.
The Major sent a boat, as he had promised, to take home my baggage, while I walked through the forest with my two boys and a guide, about fourteen miles.

For the first half of the distance there was no path, and we had often to cut our way through tangled rattans or thickets of bamboo.
