The *Śirâs* are divided into four groups: (1) the arteries for conducting the blood, (2) the lymphatics for conducting the lymph, (3) a class of bile-ducts, and (4) a class of ducts for the *Vâyus*, the currents which work the automatic and reflex machinery of the living organism. In each group there are 10 trunk *Śirâs*, which sub-divide into 175 cords, and further ramify minutely all over the body, even as a network of minute fibrils covers the leaf of a tree.
