Yes.  The process that was carried out, was really in two stages.  We received the skull from, sent to us by Dr Naidoo.  There has been an anthropological assessment of the skull, for example that we were dealing with an African female, and basically we were then asked to carry out a reconstruction based on that basis, which we did.
	The technique we used, was to place the skull onto a platform, acquire the information using a laser scanner by beaming a leisure scanner onto the skull to pick up all the co-ordinates of the skull, which are then transmitted and produced a three dimensional picture within the computer.  This was then used as our scaffolding, shall we say, for us to place a face on top of this skull.
	We use a face of someone of approximately the same type of age group initially, and it acts as a facial mask and that facial mask then moulds onto the underlying skull.  Obviously it doesn't just kind of fit over like a glove, you have to put landmarks on the skull and put landmarks on the face, which correspond to each other, to be able to produce this.  Also taking into account ...(indistinct) data that is available for that particular racial grouping.
	So that was all carried out and we produced a facial reconstruction on that basis.  That was really to see whether the shape of the face would be in keeping with the photographs that we received.  It was ... (break in recording) ...  we used a technique called video superimposition, which has been well established since the late 1970s, and used effectively in numerous court cases throughout the world, this technique.
	What we do is, we capture the image of the photographs of the person in question, so that they are then recorded and frozen and placed onto a TV monitor.  These are then, remain static as images, and then whilst we have them on the monitor, we then use a quality broadcast camera, that is a camera which is really the highest quality that we have available, so in order to do this, we employ the Media Services Department of our University, that does lots of professional work.
	The quality broadcast camera is then, then takes an image of the skull, which is placed on a universal tripod, this is a tripod which is designed to enable us to move the skull, in order to take the skull in any direction we wish, so that we can tilt the skull forward, we can tilt it backwards, sideways and so on.
	However, we need to compare landmarks on the skull directly with the photographs, so that we can align these images properly.  The way we do this is we make markings on the photographs, we do this before they are captured, we make markings on the photographs, so that we can align for tilt and rotation, and we do similar markings on the skull as well.
	And then, whilst having the photograph of the person on the monitor, on the TV monitor, we can also see an image of the skull come onto the TV monitor at the same time, which we can then move around to get it into the same orientation exactly as the other image, and we do this by using the lines that I have mentioned, and the landmarks.
	Once we are satisfied with that, then we can do a direct comparison to see whether there is a contour match with the outlines of both images, match or whether they don't match.  We found this to be a particularly powerful technique, because it also allows us to exclude quite quickly and to give negative identifications.  However, I have to say that one of the difficulties, if the person has a reasonably normal face, is that if they match in every respect, we still cannot say a hundred percent that it is that person, but we can ...(indistinct) very strong evidence, that we believe that there is an excellent match, as with the case here.
	Obviously if we have more than one photograph, we are then in a position to improve the situation slightly and confirm our contour match, say in one view, as we did in this case as well.  We used two views and we were able to get a good match with both views.  And so really, that is the extent of my work, I then produced a video recording for your purposes, so that it could demonstrate what we did.
