40. Make full notes of the condition of the various body cavities and of the viscera immediately the autopsy is completed; and add the result of the microscopical and cultural investigation when available. As part of the card index system in use in the author's laboratory already referred to (_vide_ page 335) there is a special yellow card for P-M notes. On the face of the card are printed headings for various data--some of which are sometimes unintentionally omitted--and on the reverse is a schematic figure which can be utilised for indicating the position of the chief lesions in the cadaver of any of the laboratory animals.

Finally, the results of the action of the organism or organisms isolated may be correlated with the symptoms observed during life and the observations summarised under the following headings: Tissue changes: 1. Local--i. e., produced in the neighbourhood of the bacteria. Position: (a) At primary lesion. (b) At secondary foci. Character: (a) Vascular changes and tissue } Acute reactions. } or (b) Degeneration and necrosis. } chronic. 2. General (i. e., produced at a distance from the bacteria, by absorption of toxins): (a) In special tissues--e. g., nerve cells and fibres, secreting cells, vessel walls, etc. (b) General effects of malnutrition, etc. Symptoms: (a) Associated with known tissue changes. (b) Without known tissue changes. [Illustration: FIG. 201.--Back of post-mortem card.] ~Permanent Preparations--Museum Specimens.~--
