If, on the other hand, tools and machines are held non-living inasmuch as they only owe what little appearance of life they may present when in actual use to something else that lives, and have no life of their own-so, though in a less degree, must the non-Protoplasmic parts of the body.

Samuel Butler
On gradually increasing the concentration of the solution there comes a moment when the Protoplasmic mass is seen to contract and to detach itself from the walls of the cell.
