The Pedestrian's Record

the pedestrian's record. 105 of the blood-vessel had been paralyzed, and therefore the blood within had coagulated, because it was in contact with devitalized tissue. A was opened, and from it a thin thread of coagulated blood was ob­ tained. A small piece of mustard applied to the web of a frog's foot causes the coagulation of blood, not only underneath, but around the mustard. A burn, intense cold, the persistent application of pressure to parts, as caused by the pressure of a hat against the forehead, causes coagulation of blood, because they temporarily destroy the vitality of the part by remov­ ing nervous influence from it. further experiments and microscopical investigation have proved how the nerves, primarily affected, involve surrounding tissue in pathological results ; how by irritating the spinal cord of a frog, temporary congestion will take place over the body generally, markedly so in the webof a frog's foot, which is easily noticed by aid of the micro­ scope. From this, and other experiments too com­ plicated to be amusing to any save those engaged in physiological research, we learn how beautifully Nature works both to protect animals from disease, and to set up curative processes when it exists. The blood—the vital fluid—is from the moment of birth to the day of death continually and rapidly passing through the blood-vessels, and by this means supplying the various organs of the body with nutri­ tion. Let the blood for a moment carry in its current deleterious or poisonous compounds, and immediately an impression is made upon the nervous system, which
