and the _Christian
Virtuoso_ (1690). Several other works appeared after his death, among
them _The General History of the Air designed and begun_ (1692); a
"collection of choice remedies," _Medicinal Experiments_ (1692-1698);
and _A Free Discourse against Customary Swearing_ (1695). An
incomplete and unauthorized edition of Boyle's works was published at
Geneva in 1677, but the first complete edition was that of Thomas
Birch, with a life, published in 1744, in five folio volumes, a second
edition appearing in 1772 in six volumes, 4to. Boyle bequeathed his
natural history collections to the Royal Society, which also possesses
a portrait of him by the German painter, Friedrich Kerseboom
(1632-1690).

BOYLE, a market town of Co. Roscommon, Ireland, in the north
parliamentary division, on the Sligo line of the Midland Great Western
railway, 106-1/4 m. N.W. by W. from Dublin and 28 m. S. by E. from Sligo.
Pop. (1901) 2477. It is beautifully situated on both banks of the river
Boyle, an affluent of the Shannon, between Loughs Gara and Key. Three
bridges connect the two parts of the town. There is considerable trade
in agricultural produce. To the north of the town stand the extensive
ruins of a Cistercian abbey founded in 1161, including remains of a
cruciform church, with a fine west front, and Norman and Transitional
arcades with carving of very beautiful detail. The offices of the
monastery are well preserved, and an interesting feature is seen in the
names carved on the door of the lodge, attributed in Cromwell's soldier,
who occupied the buildings. Neighbouring antiquities are Asselyn church
near Lough Key, and a large cromlech by the road towards Lough Gara.
Boyle was incorporated by James I., and returned two members to the
Irish parliament.

BOYNE, a river of Ireland, which, rising in the Bog of Allen, near
Carbery in Co. Kildare, and flowing in a north-easterly direction,
passes Trim, Navan and Drogheda, and enters the Irish Sea, 4 m. below
the town last named. It is navigable for barges to Navan, 19 m. from its
mouth. Much of the scenery on its banks is beautiful, though never
grand. About 2 m. west of Drogheda, an obelisk, 150 ft. in height, marks
the spot where the forces of William III. gained a celebrated victory
over those of James II., on the 1st of July[1] 1690, known as the battle
of the Boyne.
