Ounce Quotes (4 quotes)

A man in twenty-four hours converts as much as seven ounces of carbon into carbonic acid; a milch cow will convert seventy ounces, and a horse seventy-nine ounces, solely by the act of respiration. That is, the horse in twenty-four hours burns seventy-nine ounces of charcoal, or carbon, in his organs of respiration to supply his natural warmth in that time ..., not in a free state, but in a state of combination.
In A Course of Six Lectures on the Chemical History of a Candle (1861), 117.

An ounce of prevention is worth a pound of cure.
Perhaps an older adage, but an example of its use appears in Pennsylvania Gazette (4 Feb 1734-5), about fire prevention, including taking care, moving live coals from a fireplace between rooms, for safety in a closed warming-pan. A midnight fire from a spilled ember might set your stairs on fire: “You may be forced, as I once was, to leap out of your windows, and hazard your necks to avoid being over-roasted.” As cited in Benjamin Franklin and J. Sparks (ed.), The Works of Benjamin Franklin (1840), Vol. 1, 134, footnote.

Coal … We may well call it black diamonds. Every basket is power and civilization; for coal is a portable climate. … Watt and Stephenson whispered in the ear of mankind their secret, that a half-ounce of coal will draw two tons a mile, and coal carries coal, by rail and by boat, to make Canada as warm as Calcutta, and with its comforts bring its industrial power.
In chapter 3, 'Wealth', The Conduct of Life (1860), collected in Emerson’s Complete Works (1892), Vol. 6, 86.

Will power is only the tensile strength of one’s own disposition. One cannot increase it by a single ounce.
In The Burning Brand: Diaries 1935-1950 (1961), 88.

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
