It is almost inconceivable that one of the brilliant colored fishes, if it chanced to escape into our ponds, should escape the fate of being eaten by some larger fish attracted by such glittering bait. The goldfish, as we see it in the aquarium, is brilliant orange above and pale lemon-yellow below; there are many specimens that are adorned with black patches. And as if this fish were bound to imitate the precious metals, there are individuals which are silver instead of gold: they are oxydized silver above and polished silver below. The goldfish are closely related to the carp and can live in waters that are stale. However, the water in the aquarium should be changed at least twice a week to keep it clear. Goldfish should not be fed too lavishly. An inch square of one of the sheets of prepared fish food, we have found a fair daily ration for five medium sized fish; these fish are more hkely to die from overfeeding than from starving. Goldfish are naturally long-lived; Miss Ada Georgia has kept them until seven years old in a school aquarium; and there is on record one goldfish that lived nine years. Too often the wonderful common things are never noticed because of their commonness; and there is no better instance of this than the form and movements of a fish. It is an animal in many ways similar to ani- mals that hve on land; but its form and structure are such that it is perfectly adapted to live in water all its life; there are none of the true fishes which Hve portions of their lives on land as do the frogs. The first pecuUarity of the fish is its shape. Looked at from above, the broader part of the body is near the front end which is rounded or pointed so as to cut the water readily. The long, narrow, hind portion of the body with the tail a
