    masses under it; while the blood which flows from a cut finger, and the saliva which moistens the mouth, show clearly that liquids exist in the body. If we were to go farther and examine closely, outside and inside, any one part of the body, the hand for in- stance, we should find it made up of quite a number of different materials. On its exterior we see skin and nails ; if the skin were dissected off we should find under it more or less yellowish-white fat; beneath the fat would lie a number of red soft masses, the muscles (answering to what we call the lean of meat) ; under the muscles, again, would be hard, rigid, whitish bones; at the finger joints, where the ends of different bones lie close together, Ave should find them covered by still another substance, gristle or cartilage. Finally, binding skin and fat and muscles and bone together, we should discover a tough stringy mate- rial, quite different from all of them, and which, since it unites all the rest, is called connective tissue. If we took any other portion of the body we should arrive at a similar result ; it, too, would be made up of a number of different materials, which materials might, as in the case of the foot, be identical with those found in the hand but ar- ranged together in a different way so as to perform another function (just as wood and nails may be used to build a house or a bridge, but are put together in a different man- ner in the two cases) ; or we might, as in the eye, find in addition to some materials found in the hand others quite unlike any of them. What different materials do we see on looking at a Land ? What others would be found on dissecting away the skin ? What is the technical name for the lean of meat ? What is the technical name of gristle ? What is connective tissue ? Are other parts of the body besides the hand made up of different substances ? Illustrate by an example ?
