The Mediastinum is a membrane by which the cavity of the breast is longitudinally divided. The tearing of it in any disease seems altogether unaccountable, unless we suppose an extraordinary loss of cohesion to have taken place without any mortification. The pericardium is a membrane surrounding the heart, and in a natural state contains some water, condensed from vapour after death.
