Hen Quotes (4 quotes)

A hen is only an egg's way of making another egg.
Attributed. In fact, Butler wrote in Life and Habit (1878), 134, of an existing saying that 'It has, I believe, been often remarked, that a hen is only an egg's way of making another egg.'
Science quotes on:  |  Egg (41)  |  Reproduction (57)

Although it be a known thing subscribed by all, that the foetus assumes its origin and birth from the male and female, and consequently that the egge is produced by the cock and henne, and the chicken out of the egge, yet neither the schools of physicians nor Aristotle’s discerning brain have disclosed the manner how the cock and its seed doth mint and coin the chicken out of the egge.
As quoted in John Arthur Thomson, The Science of Life: An Outline of the History of Biology and Its Recent Advances (1899), 126.

Every complete set of chromosomes contains the full code; so there are, as a rule, two copies of the latter in the fertilized egg cell, which forms the earliest stage of the future individual. In calling the structure of the chromosome fibres a code-script we mean that the all-penetrating mind, once conceived by Laplace, to which every causal connection lay immediately open, could tell from their structure whether the egg would develop, under suitable conditions, into a black cock or into a speckled hen, into a fly or a maize plant, a rhododendron, a beetle, a mouse or a woman. To which we may add, that the appearances of the egg cells are very often remarkably similar; and even when they are not, as in the case of the comparatively gigantic eggs of birds and reptiles, the difference is not so much in the relevant structures as in the nutritive material which in these cases is added for obvious reasons.
But the term code-script is, of course, too narrow. The chromosome structures are at the same time instrumental in bringing about the development they foreshadow. They are law-code and executive power?or, to use another simile, they are architect's plan and builder’s craft-in one.
In What is Life? : The Physical Aspect of the Living Cell (1944), 20-21.

The Pestilence can never breed the Small-Pox, nor the Small-Pox the Measles, nor they the Crystals or Chicken-Pox, any more than an Hen can breed a Duck, a Wolf a Sheep, or a Thistle Figs; and consequently, one Sort cannot be a Preservative against any other Sort.
In Ludvig Hektoen, 'Thomas Fuller 1654-1734: country physician and pioneer exponent of specificness in infection and immunity', Bulletin of the Society of Medical History of Chicago (Mar 1922), 2, 321. In the reprint of the paper alone, the quote is on page 3.

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
