To begin with, separating it entirely from the rest of the organism, let us gain an idea of the human blood, how it flows through the veins; and let us consider the human form, the system of veins, the muscular system in its connection with the bony system, all the solid structure of the body and what flows through it as fluid. And first let us confine ourselves in the fluid condition to the blood. There are, of course, other fluids present, but let us confine ourselves to the blood. Now what are the processes which are continually happening in this streaming fluidity? These processes in the flowing blood can seize hold, in one direction or another, on the walls of the organs, on the bony structure, on anything which can take on a solid formation in man: then what belongs to the blood enters into the walls of the vessels, into the muscles, into one or another of the bones, or into any containing organ. What does it become there? It becomes the impulse towards inflammatory conditions.
