loss of this area was not so well defined, and, in any case, there are known to be filamentous connexions between the greater and the lesser occipital nerves, the latter being derived from the anterior primary ramus of the same segment. Again, another possibility is direct involvement, since, as Wright and Brady (1958) (Oliver and Boyd, 1953 ;Dock, 1958), and its estimation is a recognized procedure in patients with this condition.The purpose of this investigation was to discover if the level of the serum cholesterol altered after death. If it could be established that hours or even days after death the serum cholesterol had not altered appreciably from the level just before or at death it was thought that post-mortem estimation could be taken to indicate the serum cholesterol during life and could perhaps be used in the correlation of serum cholesterol levels and the state of the arteries as found at necropsy.

The severity of aorto-iliac disease has been evaluated by direct pressure recording at the time of translumbar aortography. Pulse wave analysis confirmed the radiological appearance of 35 aorto-iliac segments and in one further segment, identified a normal haemodynamic pattern in the presence of marked degenerative disease. The method is safe, accurate, simple and relatively inexpensive.
