Of the economy of quite shallow seas, however, we are still largely ignorant. Much as has been learnt of the bionomics of the sea, it is but a commencement; and this is of course especially true of deep seas. The dredge and its kindred have, however, in less than a century enabled naturalists to compile an immense mass of knowledge of the structure, development, affinities and distribution of the animals of the sea-bed, and in the most accessible seas to produce enumerations and morphological accounts of them of some approach to completeness. (J. O. B.) DRELINCOURT, CHARLES (1595-1669), French Protestant divine, was born at Sedan on the 10th of July 1595. In 1618 he undertook the charge of the French Protestant church at Langres, but failed to receive the necessary royal sanction, and early in 1620 he removed to Paris, where he was nominated minister of the Reformed Church at Charenton. He was the author of a large number of works in devotional and polemical theology, several of which had great influence. His _Catechism_ (_Catéchisme ou instruction familière_, 1652) and his _Christian's Defense against the Fears of Death_ (_Consolations de l'âme fidèle contre les frayeurs de la mort, 1651_) became well known in England by means of translations, which were very frequently reprinted. It has been said that Daniel Defoe wrote his fiction of Mrs Veal (_A True Relation of the Apparition of Mrs Veal_), who came from the other world to recommend the perusal of _Drelincourt on Death_, for the express purpose of promoting the sale of an English translation of the _Consolations_; Defoe's contribution is added to the fourth edition of the translation (1706). Another popular work of his was _Les Visites charitables pour toutes sortes de personnes affligées_ (1669). Drelincourt's controversial works were numerous. Directed entirely against Roman Catholicism, they did much to strengthen and consolidate the Protestant party in France. He died on the 3rd of November 1669. Several of his sons were distinguished as theologians or physicians. Laurent (1626-1681) became a pastor, and was the author of _Sonnets chrétiens sur divers sujets_ (1677); Charles (1633-1697) was professor of physic at the university of Leiden, and physician to the prince of Orange; Peter (1644-1722) was ordained a priest in the Church of England, and became dean of Armagh.
