The diagnosis of cerebral hemorrhage from the other lesions of thebrain is not always easy, in consequence of the fact that a chronic cere-britis may proceed imperceptibly, and then induce apoplexy or sudden * Monthly Journal, March 1851.

It m-iy generally be observed, however, that a true exudativecerebral softening is preceded by more or less weakness of the intellect,and more especially by slowness in receiving mental impressions, orframing replies to questions, frequently combined with more or lessheadache, confusion of ideas, and perversion of motion. Much will de-pend upon the seat of the lesion, the mind being disordered most in pro-portion to the extent and nearness of the disease to the hemisphericalganglion—while motion is the more influenced, according as the centraland basic parts of the brain are affected. Then it should not be forgot-ten that whilst a cerebral softening may occasionally lead to or be com-plicated with a hemorrhage, so a hemorrhage is one of the most commoncauses of a softening. The distinction between the two under such cir-cumstances becomes very difficult. Still there can be no question that
