Possible definitions for hydric
hydride
Inorganic compound of hydrogen with another element. Three common types are differentiated by their bonding. In saline (ionic) hydrides (see ionic bond), the hydrogen is an anion, H-, and behaves like a halogen. Saline hydrides such as sodium hydride (NaH) and calcium hydride (CaH2) react vigorously with water, giving off hydrogen gas (H2), and are used as portable sources of it. Metallic hydrides, such as titanium hydride (TiH2), are alloylike materials (see alloy) with some properties of metals, such as luster and electrical conductivity. Covalent hydrides (see covalent bond) are mostly compounds of hydrogen and nonmetallic elements; they include water, ammonia, hydrogen sulfide (H2S), and methane. In polymeric hydrides, the hydrogen forms bridges between other atoms (e.g., hydrides of boron and aluminum). Those hydrides give off large amounts of energy when burned and may be useful as rocket fuels.

Hadrian
Roman emperor (117-38), Trajan's nephew and successor. After years of intrigue, he was adopted and named successor just before Trajan's death. He executed his senatorial opponents, abandoned Trajan's conquests in Armenia and Mesopotamia, and coped with unrest in Mauretania and Parthia. He traveled widely, and many of his accomplishments were related to his visits abroad. He began construction of Hadrian's Wall, and he visited and disciplined troops in Algeria and elsewhere. An admirer of Greek civilization, he completed the temple of Zeus in Athens and created a federation of Greek cities. He launched a building program at Delphi and was initiated into the Eleusinian mysteries. After his young companion Antinoü s drowned in the Nile (130), he grieved openly; he erected statues of the boy throughout the realm, and cults sprang up widely. He named Antoninus Pius his successor, to be followed by Marcus Aurelius.
