pulation of Britain the
name "dolphin" is most usually given to the beautifully coloured fish
_Coryphaena hippuris_--the dorado of the Portuguese, and it is to the
latter the poet is alluding when he speaks of "the dying dolphin's
changing hues."

Many other allied genera, such as _Prodelphinus_, _Steno_,
_Lagenorhynchus_, &c., are also included in the family _Delphinidae_,
some of which live wholly in rivers.

Beside these there is another group of largely freshwater species,
constituting the family _Platanistidae_, and typified by the susu
(_Platanista gangetica_), extensively distributed throughout nearly the
whole of the river-systems of the Ganges, Brahmaputra and Indus,
ascending as high as there is water enough to swim in, but never passing
out to sea. It is about 8 ft. long, blind and feeds on small fish and
crustaceans for which it gropes with its long snout in the muddy waters
at the bottom. _Inia geoffroyensis_, the single species of its genus,
frequents the Amazon, and reaches an extreme length of 8 ft. It is
wholly pink or flesh-coloured, or entirely black, or black above and
pink beneath. A third is the La Plata dolphin, _Stenodelphis
blainvillei_, a species about 5 ft. in length. Its colour is palish
brown, which harmonizes with the brown-coloured water of the estuary of
the Rio de la Plata. See CETACEA. (R. L.*)

DOMAT, or DAUMAT, JEAN (1625-1696), French jurisconsult, was born at
Clermont in Auvergne, on the 30th of November 1625. He was closely in
sympathy with the Port-Royalists, was intimate with Pascal, and at the
death of that celebrated philosopher was entrusted with his private
papers. He is principally known from his elaborate legal digest, in
three volumes 4to, under the title of _Lois civiles dans leur ordre
naturel_ (1689),--an undertaking for which Louis XIV. settled on him a
pension of 2000 livres. A fourth volume, _Le Droit public_, was
published in 1697, a year after his death. This is one of the most
important works on the science of law that France has produced. Domat
endeavoured to found all law upon ethical or religious principles, his
motto being _L'homme est fait par Dieu et pour Dieu_. Besides the _Lois
Civiles_, Domat made in Latin a selection of the most common laws in the
collections of Justinian, under the title of _Legum delectus_ (Paris,
1700; Amsterdam, 1703); it was subsequently appended to the _Lois
civiles_. His works have been translated into English. Domat
