projects. It is thus inserted into the vein and the Trocar then 
removed. Rubber tubing from the toxin-injecting apparatus 
having previously been attached to Canula A, it is then intro- 
mitted into Canula C now in the vein. By this method

no danger of tearing the vein after insertion as there always 
is when a sharp-pointed needle is used. Per set 1 25
