    EACH PART. I.—HEAD AND NECK The right and left sides of this region constitute each a part. Its dissection may occupy the full time, or about six weeks; two hours or more daily being devote^ to it. Its inferior boundary extends from the sternum along the clavicle, to the acromion process; and thence to the spinous process of the third cervical vertebra. It may be found impossible to follow out in one part the whole of the dissections indicated below; and therefore the dissector ought rather, if his time is limited, to make a selection for repeated dissections, following, as nearly as possible, the methods described. Many smaller points of detail may be jjassed over bv the Junior Student; and there are some which can only be observed in the most favourable condition of the subject. 1. Integument of the Cranium.—The subject being placed with the face downwards, during the first two days, the scalp and the back of the neck (to the third cervical vei-tebra) are to be dis- sected; and while this is being done, only one dissector should work at a time. An incision is to be made along the middle line, from the spinous process of the third cervical vertebra, forwards over the head, to the root of the nose, and another from immedi- ately behind the ear to meet the first at the vertex, care being tiiken not to cut deeper than through the skin. The flaps of integument thus marked out are to l)e reflected from above down- wards, the posterior one first. At the back of the neck the posterior and upper parts of the trapezius and sternomastoid mtxscles will be laid bare; and, between these, part of the splenius miiscle, and, when the trapezius is not strongly developed, a small angle of the complexus muscle will be brought into view. These miiscles are to be left undivided at this stage. On the posterior part of the cranium the structures to be examined are the occipital artery and vein, and the great occipital nerve, which pierces the complexus and trapezius
