what kind of line do you have BX 2 wire romex, K&T?

if its BX and good ground you can connect the ground to the box and
begin upgrading to all grounded outlets
----------------------

It is 2-wire (black and white) -- in a single non-metallic sheath. �I
don't know if that is called BX or whatever.

Use a pigtail socket and bulb to test if the box is grounded, by touching
the wires of the socket between the hot, black wire and the box. Some early
NM cable had an undersized ground wire that was not connected to the box via
grounding screw, but wrapped around the cable and clamped by the romex
connector or pressure clamp
