    covered with connective tissue between the occipital bone and the first cervical vertebra, and hence accessible without injury to the bones. Between the separate vertebrae the inter-verte- bral foramina lead from the canal and serve for the admission of nerves and blood vessels. Each vertebra has a spinous process above, articular processes before and behind, and transverse processes at the sides. The vertebrae are differentiated ac- cording to the size and functions of these processes. The cer- vical vertebrae have short spinous and transverse processes. The dorsal vertebrae have articular surfaces on the transverse processes for connection with the ribs. The lumbar vertebrae have long transverse processes. The sacral vertebrae are grown together to form the sacral bone or sacrum. The coccygeal vertebrae have rudimentary processes. The ribs are joined to the vertebrae by small articulations running outward in the form of an arch, and extend around to the sternum. The foreribs (true ribs) reach the sternum, while the hind-ribs (false ribs) attach themselves to the fore-ribs by means of cartilaginous ends. The dorsal vertebrae, ribs and sternum form the thorax or chest cavity. (c) There are two anterior and two posterior limbs. The anterior limbs are joined to the body only by muscles and tendons. The bones of the fore-limbs are shoulderblade (scapula), upper-arm (humerus), fore-arm (radius and ulna), fore-knee (carpals), metacarpus with rudimentary metacarpals or splints, and toe bones (pastern, coronet and coffin bone, with several sesamoidal bones. The posterior limbs are joined to the vertebral column by means of the pelvis. The bones of the posterior limbs are: Upper-leg, (femur), fore-leg (tibia and fibula), patella, hock (tarsals), metatarsus with rudimentary metatarsals or splints, and toe as in the anterior limb. 3. THE MUSCLES. The skeleton is covered with muscles which are composed of single muscle fibres lying next to one another and thus
