e last not till
after his death. It forms a complete history of the growth of the
Prussian monarchy down to the year 1756. This, like all Droysen's work,
shows a strongly marked individuality, and a great power of tracing the
manner in which important dynamic forces worked themselves out in
history. It was this characteristic quality of comprehensiveness that
also gave him so much influence as a teacher.

Droysen, who was twice married, died in Berlin on the 19th of June 1884.
His eldest son, Gustav, is the author of several well-known historical
works, namely, _Gustav Adolf_ (Leipzig, 1869-1870); _Herzog Bernhard von
Weimar_ (Leipzig, 1885); an admirable _Historischer Handatlas_ (Leipzig,
1885), and several writings on various events of the Thirty Years' War.
Another son, Hans Droysen, is the author of some works on Greek history
and antiquities.

DROZ, ANTOINE GUSTAVE (1832-1895), French man of letters, son of the
sculptor J. A. Droz (1807-1872), was born in Paris on the 9th of June
1832. He was educated as an artist, and began to exhibit in the Salon of
1857. A series of sketches dealing gaily and lightly with the intimacies
of family life, published in the _Vie parisienne_ and issued in book
form as _Monsieur, Madame et Bebe_ (1866), won for the author an
immediate and great success. _Entre nous_ (1867) was built on a similar
plan, and was followed by some psychological novels: _Le Cahier bleu de
Mlle Cibot_ (1868); _Autour d'une source_ (1869); _Un Paquet de lettres_
(1870); _Babolein_ (1872); _Les Etangs_ (1875); _L'Enfant_ (1885). His
_Tristesses et sourires_ (1884) is a delicate analysis of the niceties
of family intercourse and its difficulties. Droz's first book was
translated into English under the title of _Papa, Mamma and Baby_
(1887). _Un Ete a la campagne_, a book which caused considerable
scandal, was erroneously attributed to him. He died on the 22nd of
October 1895.

DROZ, FRANCOIS-XAVIER JOSEPH (1773-1850), French writer on ethics and
political science, was born on the 31st of October 1773 at Besancon,
where his family had furnished men of considerable mark to the legal
profession. His own legal studies led him to Paris in 1792; he arrived
on the very day after the dethronement of the king, and was present
during the m
