The intermittent and intercurrent pulses take place when the powers are oppressed, and, as it were, borne down; but the intercurrent indicates a lesser, and the intermittent a greater injury. And, in general, that state in which the powers are oppressed and borne down, changes the pulses to inequality and irregularity in every other respect, and also in regard to strength and greatness. The pulses called myuri, being shown to be of two kinds, (for they are found either in that inequality called systematic, or in regard to one pulsation), the _failing_ or _fainting_ evince the last prostration of the powers; but, when they return, or are _recurrent_, they indicate that the powers are weak, but that they are struggling, contending, and have not yet submitted. As to the myuri, in regard to one pulsation, called _the failing_, and _the failing on both hands_ (innuentes et circumnuentes), these happen to persons who are gradually wasted by inflammations not yet resolved, and to those who are wasted from whatever cause, the bodies around the arteries being melted down. Pulses of unequal velocity, and those called _dorcadissantes_ or _goat-leap_, principally accompany febrile heat. But if the pulse render the commencement of the diastole feeble, and increase in velocity towards the end and beginning of the systole, this indicates that putrefaction is prevailing, nature hastening on the discharge of the fuliginous superfluities. But if, on the other hand, it render the commencement of the systole feeble, and rather make speed towards the diastole, you may be sure that the heat is prevailing, and longing for refrigeration. These in fever are, for the most part, accompanied by density, and sometimes greatness, if the powers be not restrained by the hardness of the instrument. When the hardness of the artery increases, and the powers are not weakened, the _double_ or _reverberating_ pulse is formed. The _undulatory_ pulse most commonly attends the more humid affections, such in particular as anasarcous swellings, lethargy, and peripneumony. When the powers of life are beginning to fail, but are still making a faint struggle, the undulatory pulse sinks into the _vermicular_; but when they decline to their lowest ebb, this last passes into the _ant-like_ or _formicans_. The hectic particularly attends those in consumption and marasmus. The spasmodic pulse takes place when the origin of the nerves is suffering from some inflammatory affection, as in frenzy and acute attacks of epilepsy, when those affected with them die while they are yet warm, contrariwise to those in syncope, for they are alive after they have become cold. The _clonodic_ or _vibratory_ pulse takes place when the wants of the system require a great diastole, and the vital powers are sufficient for that purpose, but are opposed by the body of the artery; which, from its hardness, cannot be expanded to a large diastole, as happens in great inflammations and chronic obstructions.
