    —changes which have not been hitherto described nor analysed. It will be remembered that in young anthropoids, as the neck grows in thickness and strength a wave of bone, represented by the upper curved lines on the human skull, expands in front of the growing muscles and forms a wide occipital crest. (Fig. 8.) In acromegaly a similar change occurs. In Fig. 12 is shown the area of a normal English Fig. 12. NUCHAL ATTACHMFWT The area of attachment of the neck in the type skull (unshaded); the increase in the acromegalic skull is shown by the shaded area (two-thirds natural size skull to which the neck muscles are attached. On to the right side of the area is placed the corresponding part of the Greenwich skull; on the left half is superimposed the nuchal area of O’Brien’s skull. The extent to which these two crania exceed the normal as regards the nuchal area is shown by the shaded marginal area. In acromegaly the muscles of the neck obtain a wider area of attachment. The extent of this area in the type skull is 8120 mm^..
