some of his relatives to witness his abjuration of Christianity,
which actually took place within the residency itself. As the climate
began to affect his health, the maharaja at length left Aden and
returned to Europe. He stayed for some time in Russia, hoping that his
claim against England would be taken up by the Russians; but when that
expectation proved futile he proceeded to Paris, where he lived for the
rest of his life on the pension allowed him by the Indian government.
His death from an attack of apoplexy took place at Paris on the 22nd of
October 1893. The maharaja's eldest son, Prince Victor Albert Jay
Dhuleep Singh (b. 1866), was educated at Trinity and Downing Colleges,
Cambridge. In 1888 he obtained a commission in the 1st Royal Dragoon
Guards. In 1898 he married Lady Anne Coventry, youngest daughter of the
earl of Coventry. (G.F.B.)

DHULIA, a town of British India, administrative headquarters of West
Khandesh district in Bombay, on the right bank of the Panjhra river.
Pop. (1901) 24,726. Considerable trade is done in cotton and oil-seeds,
and weaving of cotton. A railway connects Dhulia with Chalisgaon, on the
main line of the Great Indian Peninsula railway.

DIABASE, in petrology, a rock which is a weathered form of dolerite. It
was long widely accepted that the pre-Tertiary rocks of this group
differed from their Tertiary and Recent representatives in certain
essential respects, but this is now admitted to be untenable, and the
differences are known to be merely the result of the longer exposure to
decomposition, pressure and shearing, which the older rocks have
experienced. Their olivine tends to become serpentinized; their augite
changes to chlorite and uralite; their felspars are clouded by formation
of zeolites, calcite, sericite and epidote. The rocks acquire a green
colour (from the development of chlorite, uralite and epidote); hence
the older name of "greenstones," which is now little used. Many of them
become somewhat schistose from pressure ("greenstone-schists,"
meta-diabase, &c.). Although the original definition of the group can no
longer be justified, the name is so well established in current usage
that it can hardly be discarded. The terms diabase and dolerite are
employed really to designate distinct facies of the same set of rocks.

The minerals of diabase are the same as those of dolerite, viz.
olivine, augite, and plagioclase fe
