"The story was dreadful, dear, but it was only a story, you know: the upas tree did not kill people at all; and to turn the milky juice into a dangerous poison took a great deal of time and trouble. It was mixed with various spices and fermented; when ready for use, it was poured into the hollow joints of bamboo and carefully kept from the air. Both for war and for the chase arrows are dipped in this fatal preparation, and the effect has been witnessed by naturalists on animals, and also on man. The instant it touches the blood it is carried through the whole system, so that it may be felt in all the veins and causes a burning sensation, especially in the head, which is followed by sickness and death."
