Some labormay now be saved by filling the space beneath the jaw, and the hollows Restoration of the Face 103 under the zygoma, with cotton, held in place by plastihna. The orbits,however, must be left until later. After determining the exact location of one of the points to use,a covering of plastilina may be put on, guessing at the thickness, andthen testing with a needle and disc, as in the first researches with Figure 30. Diagram of a human skull, showing the points used in the scientificrestoration of a face. Front view. {After Kollmann and Biichly.) or, perhaps better, a narrow strip of paper of the thickness of writingpaper may be cut to a length of the exact thickness desired, and imbeddedin the plastilina. In actual use the strips are cut about a millimeter wide,and bent across the middle at a right angle. One arm is then measuredand cut to the length required; the other serves as a foot, and may be 104 Personal Identification stuck down upon the bone surface with the plastiUna. See that themeasured piece projects perpendicularly from the surface of the bone,and then build up on both sides of it with little pellets of plastiHna, beingcareful not to bend it. There is thus formed a cone or pyramid indicating
