an objection has, therefore, been as truly sanguineous as in entonic apoplexy; and hence a valid objection to the use of the sanguineous term sanguineous as descriptive of the entonic form alone.al “ It is ”, says M. Portal, “an error to believe that the of the en

Institute, died of this precise kind of the disease at an advanced age: and Zulianus describes a case marked by a pale countenance, and a pulse so weak as scarcely to be felt, which, on examination after death, was found to be an apoplexia verè sanguinea : and another in which, after all the symptoms of what is ordinarily called serous apoplexy had shown themselves, extravasated blood was discovered in the brain without any effusion of serum, or the smallest moisture in the ventricles t.

It is nevertheless true that atonic apoplexy is often Yet this found with an effusion of serum instead of an effusion of blood, and apparently produced by such sereus effusion ; an effusion

On the attack of the plexia atoparoxsym the patient is as completely prostrated as in the entonic variety, but the symptoms are less violent, though plexy.. not on this account less alarming, in consequence of the greater debility of the system. The countenance is here pale or sallow, instead of being flushed, but at the same time full and bloated; the pulse is weak and yielding, sometimes, indeed, not easy to be felt; and the breathing though always heavy and laborious, not always, as we have already observed, noisy or stertorous. If spasms occur, they are uniformly of the convulsive or clonic kind. The Duration of duration of the fit varies as in the preceding variety, and the if the patient recover, he is more liable to a relapse, and more in danger of hemiplegia or some other form of paralysis than in the stronger modification of the disease.

From these remarks on the two varieties of apoplexy, Disease unwe may readily see why this complaint, and its ordinary

The former, being most incident to the luxurious and indolent, most frequently occur in private practice, and among the upper ranks of life. The latter occur more among the laborious
