1. Laboratory

   A laboratory is a facility that provides controlled conditions in which scientific research, experiments, and measurement may be performed. Labs used for scientific research take many forms because of the differing requirements of specialists in the various fields of science. A physics lab might contain a particle accelerator or vacuum chamber, while a metallurgy lab could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's lab might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers are used for either simulations or the analysis of data collected elsewhere. Scientists in other fields will use still other types of laboratories. Despite the great differences among laboratories, some features are common. The use of workbenches or countertops at which the scientist may choose to either sit or stand is a common way to ensure comfortable working conditions for the cabinets for the storage of laboratory equipment is quite common. It is traditional for a scientist to record an experiment's progress in a laboratory notebook, but modern labs almost always contain at least one computer workstation for data collection and analysis.

   A department which is intrusted with the manufacture of combustible and other substances for military purposes, such as blank and ball cartridges for small-arms, cartridges for every description of ordnance, rockets, and all stores of similar character. This department is likewise intrusted with the conservation, packing, restoring, and supply of all gunpowder to the several military and naval departments, and in the British service is under the management of officers of the royal artillery especially appointed to that duty; in the U. S. service it is under the officers of the ordnance department. In the latter service officers of artillery, as well as non-commissioned officers and privates, are instructed at the artillery school, Fort Monroe, Va., in laboratory duties, and carefully taught the manipulation and manufacture of laboratory stores. At the West Point Military Academy, the cadets are thoroughly instructed in the above duties, as are also the naval cadets at the Naval Academy, Annapolis, Md. In the British service officers of artillery, as well as non-commissioned officers and gunners, are instructed in laboratory duties. Officers and non-commissioned officers of artillery in Germany, France, and Austria are required to possess a knowledge of the manufacture and care of laboratory stores.
