A great part of the acid juice is converted into sugar as the fruit ripens, and even after it is gathered, by natural process, termed maturation; but, when apples decay, the sugar is changed into a bitter principle, and the mucilage becomes mouldy and offensive.

It suggests at once that maturation, the transformation of the child into the man or woman, must be due to the pouring into the blood and the body fluids of some substance which acts like the yeast in the fermentable solution.

This is the process of maturation.

The ovary is the organ for the preservation and maturation of the germ plasm, that treasure which the body is built but to cherish and hand on as a sacred heirloom.

This maturation is not at all universal.

Maturation is especially observed in the fruits of trees; which are then said to be ripe, when the seeds are fit to be sown again.

Maturation of Wine.

In the examination of the materials appropriated by plants from the soil, we find that mineral substances are sometimes taken up in solution in larger amount than the growth of the plant and the maturation of its fruit require, and the excess is deposited again, in crystalline form in the substance of the plant.

It is necessary that of every play the chief action should be single; for since a play represents some transaction, through its regular maturation to its final event, two actions equally important must evidently constitute two plays.

* CHANGES DURING THE MATURATION OF FRUIT.

It is during this period that maturation commences.

The acids react on the cambium, which flows into the fruit, and, aided by the increased temperature, convert it into saccharine matter; at the same time they disappear, being saturated with gelatine, when maturation is complete.

The characteristic constituent of unripe fruit, however, is pectose, an element insoluble in water, but which, as maturation proceeds, is transformed into pectic and pectosic acids.
