infix

With serpents were their hands behind them bound, Which through their reins infix'd the tail and head Twisted in folds before.

It is more than to infuse, it is to infix it in such a manner as that it never may wear out.

I have a friend who loves me as his life, and in whose breast I should infix a mortal sting if I ungratefully left him.

The lower infix is quite regular in all of the forms, being a circle or ring.
