The Life of a Cell. It is probable that the great ma-jority of cells are, comparatively speaking, short-lived.We must remember that the body is constantly andrapidly changing. Each movement of the body, eachactivity of a part, must cause a wear and waste oftissue ; and this loss must be replaced by new mate-rial within a short time. There are many ways of showing that the body is everwasting away. If a drop of saliva be placed under themicroscope, a vast number of thin cells can be seen.These cells come from the mucous membrane lining themouth. The motion of the tongue, lips, and cheeks, as PLATE I.. CELLS. 13 in speaking*, eating, and drinking, remove vast numbersof these bodies. Then again, the surface of the wholebody is covered with cells, many layers deep. Theouter cells are easily removed, by the friction of theclothing, and by the use of the sponge and towel atthe daily bath. In this way immense numbers of cellsare being constantly destroyed, while new ones are asrapidly being formed beneath the surface to take theirplaces. A more familiar example will illustrate this point.The finger nails are composed of cells so minute thata high power of the microscope is required to see them.Each paring of the nail, therefore, must remove vastnumbers of these cells ; and yet, how rapidly even thishard structure grows. Thus we learn that the body isever changing; the old, worn-out, and useless materialbeing constantly cast off, and the new as regularly tak-ing its place. Some cells are much lon
