Some additional Experiments and Observations on the relation which subsists between the nervous and sanguiferous systems; by A. P. Wilson Philip, Physician in Worcester.

London Monthly Magazine, for January, 1816.

A few months since we noticed Mr. Carpue's successful restoration of the nose of Capt. Williamson, and we have now the pleasure to state, that he has since succeeded in performing a similar operation on Capt. Latham. The same eminent surgeon has recently extended the principle, and has restored an entire lower jaw to an officer who had lost it in battle, by uniting the integuments of the neck with those of the under part of the face. Id.

Sir Everard Home has published some interesting observations on the influence of the nerves upon the action of the ar teries. That the pulsations of the arteries correspond in their frequency with the contractions of the left ventricle of the heart, is, says he, universally admitted; and those pulsations continuing in the arteries after the limb to which they belong is rendered paralytic, has led to the belief, that all arterial action is independent of nervous influence; but he proves, that the nerves which accompany the arteries regulate their actions, and it is through their agency that the blood is distributed in different proportions to the different parts of the body. He ascertained by experiment, that the increase and the diminution of the action of an artery does not depend upon irritability, but nervous influence; and this influence of the nerves upon the arteries throws, he says, considerable light upon some of the most important actions in the animal economy.

By its means, the same arteries, at different times, allow very different proportions of blood to pass through them, and those employed in furnishing blood for the secretions have the supplies regulated; which explains the use of the system of nerves with which the blood-vessels of the viscera are so abundantly furnished. On this dominion of the nerves over the actions of arteries depends the growth of the body, the regeneration of parts in those animals, in which it occurs, as lizards and others, and the formation of tumours of all the different kinds. The circulation of the blood is therefore no longer to be considered as wholly dependent upon the heart and the elasticity of the arteries; for, although by these alone it can be kept up, the action of the nerves is necessary to regulate the distribution of the blood to the different parts of the body, according as supplies are wanted to carry on the necessary operations of the animal economy.
