more capable of resistance than themselves. For example, several species of Entozoa 

 have been found in a living state within meat after it has been cooked, especially in those 

 spots where the heat had not penetrated sufficiently to destroy the natural ruddiness of 

 its colour. It is known that " measly " pork derives its peculiar aspect from the presence 

 of Entozoa, and that many of these Entozoa, or, at all events, their eggs, are swallowed by 

 human beings, within whom they make their homes, and whom they condemn to infinite 

 worry, pain, and weakness.

 severe process of being thoroughly dried appears to be quite as ineffectual to destroy these

 become quite dry, and were apparently nothing more than flat slips of membrane 

 adhering to a board, began to revive as soon as they were wetted, and actually moved the 

 moistened part of their bodies, while the remainder was still dry and adhering to the 

 board.
