“The study of the disperse systems is a border-land of science where the most different branches of knowledge meet and shake hands.”

“The proteins are the most important substances in the organic world.”

“Progress in this field is entirely dependent on the further development of the methods of measurement.”

“It has been said that the physicist, chemist, and biologist have respective heavens of their own.”

“The ultracentrifuge has made it possible to determine the molecular weights of the proteins in a far more direct and reliable way than was possible before.”
