Laboratory
Definition:
(n.) The workroom of a chemist; also, a place devoted to experiments in any branch of natural science; as, a chemical, physical, or biological laboratory. Hence, by extension, a place where something is prepared, or some operation is performed; as, the liver is the laboratory of the bile.
