elatives and others, with whom the living
are said to be surrounded. More vaguely it includes the power of gaining
knowledge, either through the spirit world or by means of psychometry
(i.e. the supernormal acquisition of knowledge about owners of objects,
writers of letters, &c). Some evidence for these latter powers has been
accumulated by the Society for Psychical Research, but in many cases the
piecing together of normally acquired knowledge, together with shrewd
guessing, suffices to explain the facts, especially where the
investigator has had no special training for his task.

CLAMECY, a town of central France, capital of an arrondissement in the
department of Nievre, at the confluence of the Yonne and Beuvron and on
the Canal du Nivernais, 46 m. N.N.E. of Nevers on the Paris-Lyon
railway. Pop. (1906) 4455. Its principal building is the church of St
Martin, which dates chiefly from the 13th, 14th and 15th centuries. The
tower and facade are of the 16th century. The chevet, which is
surrounded by an aisle, is rectangular--a feature found in few French
churches. Of the old castle of the counts of Nevers, vaulted cellars
alone remain. A church in the suburb of Bethlehem, dating from the 12th
and 13th centuries, now serves as part of an hotel. The public
institutions include the sub-prefecture, tribunals of first instance and
of commerce and a communal college. Among the industrial establishments
are saw-mills, fulling-mills and flour-mills, tanneries and
manufactories of boots and shoes and chemicals; and there is
considerable trade in wine and cattle and in wood and charcoal, which is
conveyed principally to Paris, by way of the Yonne.

In the early middle ages Clamecy belonged to the abbey of St Julian at
Auxerre; in the 11th century it passed to the counts of Nevers, one of
whom, Herve, enfranchised the inhabitants in 1213. After the capture of
Jerusalem by Saladin in 1188, Clamecy became the seat of the bishops of
Bethlehem, who till the Revolution resided in the hospital of Panthenor,
bequeathed by William IV., count of Nevers. On the _coup d'etat_ of 18
