The liver may present several morbid phenomena, which, in a dissection instituted for the purpose of discovering the cause of death, ought not to be overlooked. It may also be found ruptured, an occurrence which may take place where little or no external injury can be perceived, as from a sudden fall, or from the application of strong pressure applied to the upper part of the abdomen, such as might be occasioned by the passage of a heavy carriage over the body.
