The Muscles.—The great mass of the body external to theskeleton is composed of the flesh, or Muscles, which largely de-termines its outline and weight. The muscles are the organs ofmotion. Their number is about four hundred, and to each of themis assigned a separate and distinct office. They have all beenstudied, one by one, and a name given to each, by the anatomist.Each is attached to bones which it is designed to move. A few arecircular in form, and enclose cavities, the size of which they dimin-ish by contraction. 2. If we examine a piece of flesh, we observe that it is soft, andof a deep red color. Its structure appears to be composed of layers and bundles of small fibres
