Minot, the embryologist, and Drummond, the scientist, tells us that only by losing its life does the cell save it.

The new science exhibits the body as a temple, constructed out of cells, as a building is made of bricks.
Just as some St.Peter represents strange marble from Athens, beauteous woods from Cyprus, granite from Italy, porphyry from Egypt, all brought together in a single cathedral, so the human body is a glorious temple built by those architects called living cells.

When the scientist searches out the beginning of bird or bud or acorn he comes to a single cell.

Under the microscope that cell is seen to be absorbing nutrition through its outer covering.

But when the cell has attained a certain size its life is suddenly threatened.
