TRANSECTION OF A MAMMAL. 43 It is often desirable to describe the place of origin or insertion of muscles as from or upon a given fraction of the entire length of a long bone. When the area extends over a third of the whole length the thirds would be designated usually as proximal, middle or distal; but when fourths or smaller subdivisions are emplo3-ed, they may be designated as first, second, etc., as shown upon the femur in Fig. 6. Dorsal aspect.

In Fig. 7, the cut surface is viewed from the caudal aspect, so that the right and left parts ai'o as in the other diagram (Fig. 6). As a whole, the body is symmetrical, the two halves being reversed repe- titions of one another on opposite sides of the meson. ISTo definite separation exists between the dorsal and the ventral regions. We may, however, speak of the dorsal and the ventral aspects, and the vertebral column, or main axis of the soma, intervenes between the dorsal cavity, or Canalis neuralis, and the ventral cavity, the ccelum, whose more cephalic division or thorax is here transected. The Canalis neuralis contains the myelon, and the coelum the organs of organic life, the tlioracic, aidoniinal and 2}elric viscera. The following parts and organs are mesal or approximately so, at least in the embryo: nose, tongue, myelon, centra ve7-tebrartim, aorta, (esophagus, trachea, heart, steryium. The following are in pairs: eyes, ears, kidneys, costce, costicarlilagines (costal cartilages), pulmones (lungs), pleura?. limt?s. The right lung is shown as a single and simi^le sack,
