Taghairm (2 syl.).
A means employed by the Scotch in inquiring into futurity. A person wrapped up in the hide of a fresh-slain bullock was placed beside a waterfall, or at the foot of a precipice, and there left to meditate on the question propounded. Whatever his fancy suggested to him in this wild
situation passed for the inspiration of his disembodied spirit.
