    I. Factors causing increased trB^nsMdsition—continued. B. Increased permeability of vessel wall: a. Local injury by mechanical irritants. ,, thermal „ ,, ,, ,, chemical ,, b. Malnutrition. c. General injury by circulating poisons (?). C. Watery condition of blood (hydraemia). D. Increased molecular concentration of tissues. II. Factors causing diminished absorption:— A. By lymphatics: a. Paralysis of limbs. &. Obstruction of lymphatic trunks. B. By veins: a. Venous obstruction. h. Watery condition of blood. c. Concentrated transudations {i.e. in protein). It is important to remember that probably under no cir- cumstances can dropsy be ascribed to an abnormal change in one only of these processes. This however can also be said of any other diseased condition of the body. We know that the organism responds to a destruction of a considerable part of the excretory apparatus of the kidney by sending up the general blood pressure, and so driving an increased amount of blood through the still healthy glomeruli. But we cannot say that two-thirds of the kidneys are practically inactive under normal conditions, because excision of two-thirds causes no change in the general condition of the animal nor any appreciable heaping up of urea in the blood. In the same way we find that the organism has various powers of accommodating itself to changed conditions in its lymphatic apparatus, so that it is in most situations difficult to upset the normal balance—i.e., cause dropsy—by altering only one of these factors, unless the alteration be of a very extreme degree. In nearly all cases the dropsy is
