But if the organ from any cause become weakened in its vascular powers, that weakness will extend to one or both the sets of vessels we are now considering, and the result will necessarily be the existence of brainy matter of a depraved and untempered tenacity. The secernents may not pour it forth in a sufficient abundance to supply the waste, or they may pour it forth in a dilute and unelaborated crasis, whence the general tissue must be soft and pulpy: or if the material be duly attempered as furnished by the secernents, the absorbents may be too debilitated to imbibe more than the thinner and attenuate parts of the texture when worn out by use, and leave the grosser behind ; in which case the matter of the brain, at least in the regions thus affected, must necessarily be rendered morbidly tough or even horny.. And hence both extremes may proceed from the same Both may cause operating in a different way or upon different sets of pro vessels. And there can be no question that in proportion same cause. as the compages of the brain becomes looser and less resistible, effusions of serum and red-blood, ulceration. gangrene, and a total dissolution of the entire substance, must in many cases follow as a natural result, and in the order here stated. And hence in cancer of the brain the substance of the organ is always found in a soft or mollescent state. As a further proof that this peculiar change is for the most part a result of debility, it is admitted by both M. Rostan and M. Lallemand that it is by far most frequently met with in persons of advanced age; the Pulpy brain

Morgagni has endeavoured to show, but without success, that this distinction was in existence among the Greek writers. It is a distinction, however, that runs, not only through his own works, but through those of Boerhaave, Sennert, Mead, Sauvages, and Cullen, and is acknowledged by most practitioners of the present day.

It is in this form of the disease that we chiefly meet with, and are almost always sure to find, a snoring or stertorous breathing; nor is this difficult to be accounted for, since the vessels of the trachea, and particularly those

And to the same effect Dr. Cooke and the most celebrated Further pathogolists who have preceded him. “Boerhaave”, says

he, “measures the strength of the disease by the degree of stertor; and Portal agrees with him in opinion on this subject; observing that respiration in apoplexy is greatly impeded and the motions of the breast are very apparent. We hear a noise of snoring or stertor," he says, “which is great in proportion as the apoplexy is strong. In all the cases of strong apoplexy which I have seen, the respiration in the beginning of the paroxysm was laborious, slow, and stertorous; and in those which proved fatal, this symptom as far as I can recollect, remained, even when the breathing had became weak and irregular."*
