Summary1. Current theories of ophidian evolution suggest that the snakes have been derived either from aquatic, above‐ground terrestrial, or burrowing ancestors. It is generally supposed that the ancestors of snakes, irrespective of their habits, were closely related to the platynotid lizards.

From splines and snakes to snake splines
1993Segmenting 3-D complex medical objects from sets of parallel slices may be a difficult task. We propose a new method of active contours (or snakes) that simplifies the classical approach of snakes by embedding the intrinsic energy in the spline nature of the surface to deform.

Effects of Snake Venoms on Snakes
Copeia, 1946IN 1931 I started a series of experiments on snake venoms in order to procure comparative data on the effects of venoms on various species of snakes. The war brought the work to a standstill in 1941, after I had concluded 58 experiments. Although the small number of experiments does not permit definite conclusions to be drawn, the work is now ...

Snake venoms are complex mixtures containing many different biologically active proteins and peptides. A number of these proteins act on components of the haemostatic system in humans. The paper focuses on those venom constituents that affect the blood coagulation pathway, endothelial cells and platelets. Several highly purified venom enzymes have been
