(4) The dead portion can undergo sequestration, a capsule of con- nective nature being formed by reactive inflammation (lungs, muscles), or the primary pleuro-pneumonia process comes to a standstill, and the tissue become transformed into a cicatrice by opposition of connective tissue (subcutaneous tissue). (5) The lesions of pleuro-pneumonia having originated by metastasis present microscopically the image of a corpuscular infiltration with pronounced serofibrinous exudation, without there being any localisation of the process within definite portions of the tissue. It is in the nature of the virus to form metastases, especially in the joints, the age of the affected animal being apparently immaterial. (6) The histological lesions around the vessels differ from those of chronic productive pneumonias, and can be used with certainty for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Transvaal (Colony) Dept. of Agriculture.
