This is used as a guiding a second line one inch posterior to the first but parallelwith it, then saw through the bone, following the secondline. Draw two other lines, one on either side of thecraniimi. Start each line at the end of the transverse inci-sion made with the saw, and carry it backward across the 64 VETERINARY POST-MORTEM TECHNIC temporal and occipital bones parallel to the top of thezygomatic process, and tenninate each line in the foramenmagnum above the occipital condyles (Fig. 65). Cutthrough the temporal and occipital bones with a curved bonechisel or a wide blade steel brick chisel, following these Fig. 66.—Removal of the calvarium with the hammer-hook. When the three incisions described have been completedplace the hook end of the steel hammer-hook under theanterior margin of the calvarium or skullcap and gentlypull it upwards (Fig. 66). If the bones have been com-pletely severed the calvarium will be removed easily, ex-posing the meninges and brain (Fig. 67). Examine the INTERNAL EXAMINATION OF THE HORSE 65 dura mater, then penetrate it with a groove director, andwith a sharp scalpel incise it longitudinally and lay it remove the brain work the fingers between the organand the cranial bones, beginning anteriorly and taking great
