Probably if half a kilogram [of radium] were in a bottle on that table it would kill us all. It would almost certainly destroy our sight and burn our skins to such an extent that we could not survive. The smallest bit placed on one’s arm would produce a blister which it would need months to heal.
As quoted in 'Radium', New York Times (22 Feb 1903), 6. Note that X-rays were discovered only a few years before, in 1895, radioactivity in 1896, and the electron in 1897. Full knowledge of the harmful radiation did not exist at the time. Nevertheless, Crookes’ remark, in the words of the reporter, “would seem to indicate that it [radium] emits something more than light. Heat and actinic energy must make up a large part of its radiation. It also emits electrons with [great] velocity…”

The French kilogramme = 15,433.6 grains, or 2.679 lbs. Troy or 2.205 lbs. avoirdupoids.
In Elementary Chemistry, Theoretical and Practical (1854), 104. [Note: this shows, at the time of writing, the grain was the preferred unit of mass.]

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
