Testing (Process of examining reagents)

the process of examining reagents, with the view of discovering their composition. The term testing is usually confined to such examinations as seek to determine what chemical elements or groups of elements are contained in any substance, without inquiring as to the quantity of these elements. Testing is carried out either by the application of chemical reactions to solid substances, or by the application of reagents in solution to a solution of the substance under examination.

Testing Needles

Small strips of steel with gold points, usually running from 4k. to 20k. inclusive, and used in conjunction with a touchstone for determining the quality of gold. The gold to be tested is first rubbed upon the touchstone, and the needle which most closely approximates to it in quality, in the judgment of the operator, is also rubbed upon the stone. The two marks are then treated with nitric acid and the difference in color indicates the difference in quality of the two marks. See Touchstone.

Testudo

among the ancient Romans, a defensive cover or screen formed by overlapping shields. The name comes from testa, meaning a shell, particularly a tortoise shell. When a party of Roman soldiers advanced to storm a wall or against the enemy they were wont to close up their files. Each man elevated his oblong shield or target above his head, overlapping it with that of his comrades in such a way that the shields of the company formed a roof or protection against the darts or other missiles of the enemy. Caesar relates that on one occasion the javelins of the enemy hurled through the air fell upon the testudo and pinned the edges of the shields together in such a way that it was difficult for the soldiers to pull their targets apart when they desired to engage the enemy individually. The term was applied also to a movable structure on wheels or rollers used for protecting sappers and miners as they endeavored to undermine a wall.
