The lymph, the second life-giving fluid, is first drawn from the chyle,
the milky juice, into which all food is converted after it leaves the
stomach, and after having directly fed the nerves, enters the blood
through the ductus thoracicus, and accompanies it in its circulation.
According to its nature some degenerations of the lymph tissue are
coincident with degenerations of the blood, and especially the plasma,
such as Scrofulosis, Tuberculosis, Syphilis and Cancer, while other
degenerations of the lymph tissue coincide with degenerations of the
lymph-fed nerve tissue and are consequently treated under that heading.
