Not illustrated. 1825 edition. Excerpt: ...glands. Even the osseous and the pilous systems, being essentially connected with secretory action, are often participators in the ravages of fever. If the source be disordered, the product must suffer. From the interest attached to it, as a topic in pathology, and its great importance as a guide in practice, the diseased pulse, which constitutes such a prominent symptom of fever, is entitled to a few additional remarks. For its preternarural frequency, fulness, and force, it is indebted to the action of the heart. Its tension and hardness, as well as its contracted and wiry character, arise from the peculiar state of the arteries. When in a healthy condition, the large arteries do but little to promote the circulation of the blood, that function through them being performed almost entirely by the action of the heart; when diseased, their agency tends to impede it. In the number and times of its beats, the pulse nccessarily corresponds with the contractions of the ventricles of the heart. Bearing towards each other the relation of cause and effect, these movements are and must be, alike infrequency. Nor is it true, as is often asserted, that the pulse, in one arm, is ever more frequent than it is in the other. In both arms, and in every other part of the body, it moves only in obedience to the contractions of the heart; consequently its beats are, in all parts, synchronous with those contractions, and with each other. When, therefore, the heart contracts frequently, the pulse is frequent, and the reverse. If the heart contract with such vigor and effect as completely to empty its cavities of their blood, the pulse is full, and usually strong. When the cavities are not thus emptied, the volume and force of the pulse are proportionally..
