It is not an easy matter to draw a fast and sharp line between the symptoms of chronic nephritis and the complications which occur with greater or less frequency in this disease. Indeed, the symptoms of the different forms of chronic inflammation of the kidneys may become so serious as to constitute complications of the gravest character and necessitating the most careful management.
I shall not attempt in the present article to study all the complications of chronic Bright's disease, nor shall I attempt to consider any of them in very great detail, but I wish to bring to your attention some of those which seem to me most important, either from the frequency of their occurrence or the gravity of the symptoms to which they give rise. I propose to study them under the following headings:
1. The cardiac and vascular complications.
2. Those connected with the nervous system.
