Some additional experiments and observations on the relation which subsists between the nervous and sanguiferous systems

This paper comprises a series of very numerous experiments on the effects of various stimuli applied to the brain and nerves of rabbits and frogs, in exciting the voluntary muscles, the heart, and the blood-vessels; from which the author infers,— That the laws which regulate their effects on the muscles of voluntary and involuntary motion are different. That both mechanical and chemical stimuli applied to any part of the nervous system tend to increase the action of the heart.
