Poisonous Quotes (3 quotes)

Chlorine is a poisonous gas. In case I should fall over unconscious in the following demonstration involving chlorine, please pick me up and carry me into the open air. Should this happen, the lecture for the day will be concluded.
Quoted in Ralph Oesper, The Human Side of Scientists (1975), 192.

In the wilderness, people think of danger from Indians, alligators, and jaguars. They are not the things you mind. It is the mosquitoes, the poisonous ants, the maribondo wasps that are perfectly awful. It is the borrachudos and plum flies—like the black flies of the north woods, only worse … The day after I threw away my spare clothing ants ate up all my underwear. These were white ants. The driver ants try to eat the man instead of his clothes.
In National Geographic, Great Adventures with National Geographic: Exploring Land, Sea, and Sk (1963), 109. The last sentences about the white and driver ants, with slightly different wording, also appear in Theodore Roosevelt, 'A Journey in Central Brazil', The Geographical Journey (Feb 1915), 45, No. 2, 104, previously read to the Royal Geographic Society (16 Jun 1914).

When the morning breezes blow toward the town at sunrise, if they bring with them mists from marshes and, mingled with the mist, the poisonous breath of the creatures of the marshes to be wafted into the bodies of the inhabitants, they will make the site unhealthy.
Vitruvius
In De Architectura, Book 1, Chap 4, Sec. 1. As translated in Morris Hicky Morgan (trans.), Vitruvius: The Ten Books on Architecture (1914), 16.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
