"Presently in the production of ordinay connective tissue, fibers of two kinds make their appearance in the intercellular substance, and to all appearance independent of the cells. Those of the one kind are highly elastic and refracting, not easily affected by reagents, stain deeply with magenta, run singly, always branch, and become united with neighboring fibers so as to form a network throughout the tissue." — Encyclopedia Britannica, 1893

"Presently in the production of ordinay connective tissue, fibers of two kinds make their appearance in the intercellular substance, and to all appearance independent of the cells. Those of the other kind are excessively fine and indistinct, never run singly but always in bundles, and generally with a wavy course, are readily affected by reagents, and, in vertebrates, yield gelatin on boiling." — Encyclopedia Britannica, 1893
