The Interdependence Of Diseases

My present object is to exhibit in a conspicuous manner the Interdependence of Diseases. (See "Preliminary Remarks,") I have, therefore, restricted myself to a statement of the influence exerted by the vestiges of each of the diseases analysed in the preceding Lectures upon the rest of the same little group, and in order that the different relationships may be seen at a glance I have arranged the facts in a tabular form.

In the following tables the first column gives a list of the vestiges of the disease at its head. The second column shows to which of the diseases already analysed each vestige may become the predisposing cause; the third column shows to which of these it may become the es sential cause; and the fourth column shows to which it may become the cause of fatality - the heading under which it will take its place in the Registrar's Reports. It must be remembered that several vestiges usually concur in producing their effects.

Tables showing the interdependence of diseases registered under the following names :-rheumatism and gout - continued fever-apoplexy and paralysis-iieart disease and pericarditis-bronchitis-atrophy and debility.

Table Showing The Interdependence Of Winter Cough With Other Diseases

Having shown the remarkable interdependence which exists between different diseases - how they act and react upon one another - I must attempt, in this Lecture, to show to what extent one vestige of disease, or the several vestiges of one disease, may act as essential causes and as causes of death in other diseases. I will first take some Diseases which have no place in the Registrar's report. This will enable us to observe how many of the headings under which deaths are registered in that report owe their existence there to diseases which never figure at all as causes of death.

The first example I have chosen is Anaemia, a name that does not appear in the Registrar's reports.
