In my view, the Christian religion is the most important and one of the first things in which all children, under a free government ought to be instructed... No truth is more evident to my mind than that the Christian religion must be the basis of any government intended to secure the rights and privileges of a free people. Preface to 1828 Dictionary

HEDGEHOG, n. A quadruped, or genus of quadrupeds, the Erinaceus. The common hedgehog has round ears, and crested nostrils; his body is about nine inches long, and the upper part is covered with prickles or spines, and the under part with hair. When attacked, this animal erects his prickles and rolls himself into a round form, which presents the points of the prickles on all sides to an assailant.
This fish belongs to the genus Diodon. It is covered with long spines, and has the power of inflating its body, whence the name globe-fish.
The Sea-hedgehog, is the Echinus, a genus of Zoophytes, generally of a spheroidal or oval form, and covered with movable spines.
A small European insectivore (Erinaceus
Europæus), and other allied species of Asia and Africa,
