Alteration graisseuse senile des vaisseaux de l'encephale chez certain mammiferes (Vulpian Comptes-Kendus de la Societe de biologie, 1864). After having gone over this long series of causes we have only arrived at negative results; we have been able to determine the proximate cause of some exceptional cases of cerebral haemorrhage, and we have indicated causes which may often intervene, but in a secondary manner. We have not found the real cause of the haemorrhage either in exaggerated blood tension, in the morbid changes of the surrounding tissue, or even in the vascular changes hitherto described. CHAPTER IV. ON A HITHEKTO UNDESCRIBED CHANGE OF THE SMALL ARTERIES OF THE BRAIN, AS THE MOST FREQUENT CAUSE OF CEREBRAL HEMORRHAGE. Before pointing out the cause which appears to me to produce the most common forms of cerebral haemorrhage, --those which occur in old age, --I would remark that this is a line of research which has perhaps been too much neglected, and which might, no doubt, long ago have solved this important question in pathology. Before discussing the vascular changes which might produce the haemorrhage, it was well to determine the vessel whose rupture had produced effusion. An examination of its walls at the point of rapture, greatly facilitated the study of the changes which had preceded the apoplexy. This investigation, it must be owned, is not very difficult, but demands much time and minute attention. Abercrombie, who understood its importance, says that " researches to determine specially which are the torn vessels are, in general, useless." Yet M. Gendrin affirms that he has been more fortunate; and, were he not careful to...
