c33.6
*Killed* iron is that which in the shape of impalpable powder floats on water and, when rubbed between the thumb and the fore-finger, enters the lines; which, on being mixed with treacle, *Abrus precatorius*, honey and ghee, and heated, does not revert to the natural state; which floats on water like duck and does not sink down even when heavy things like paddy grains are placed over it. 25-28
