Albumen Quotes (2 quotes)
I had come to the conclusion, that the principal alimentary matters might be reduced to the three great classes, namely the saccharine, the oily and the albuminous.

The fibrous material and muscle were thus digested in the same way as the coagulated egg albumen, namely, by free acid in combination with another substance active in very small amounts. Since the latter really carries on the digestion of the most important animal nutrient materials, one might with justice apply to it the name pepsin.
'Ueber das Wesen des Verdauungsprocesses', Archiv für Anatomie, Physiologie und Wissenschaftliche Medicin (1836), 90-138. Trans. L. G. Wilson, 'The Discovery of Pepsin', in John F. Fulton and Leonard G. Wilson (eds.), Selected Readings in the History of Physiology (1966), 191.
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.
