Abstract

In this paper we have studied the moire contour fringes of the skull and femur knee joint of Nycticebus coucany and obtained the following results: 1. The skull's value K is very useful for comparative study with the different kinds of Primate. 2. The moire contour fringes of the tibia facies of knee joint is convex on one side while the other side is concave. 3. At the same condition the grade of the first moire contour fringe of connection on the femur knee joint between the two condyles and its angle β are smaller than Hylobates concolor leucongeuys. This study is significant, because: 1. The evolution of skull may be related with the increased value K. 2. The moire contour fringes of the Nycticebus coucany's tibia and femur knee joint have lower range of activity. 3. From the moire contour fringes of knee, the Nycticebus coucany and. Hylobates concolor leucongeuys are of one kind. But the moire contour Nycticebus of tibia is different form.
