(From half, and to strike). Dr. Cullen arranges it as the second species of paralysis, in which one side of the body-only is affected: of this he mentions two varieties. 1. When it occurs in plethoric, and 2. when in leucophleg-matic habits. It usually begins with, or follows, a paroxysm of apoplexy; and when the hemiplegia, after subsisting for some time, becomes fatal, it is commonly by passing again into the state of apoplexy. The relation, therefore, between the two diseases is sufficiently evident, and is further strongly confirmed by the hemiplegia coming upon persons of the same constitution, and being preceded by the symptoms of apoplexy. See Paralysis. London Medical Journal, vol. i. p. 323; vol. ii. p. 198.

Hepar. sulphuris. A sulphuret prepared by adding sulphur to a fixed alkali, chiefly employed in medicine as a counterpoison of hydrargyrus muriatus and arsenic. When an acid is added, the gas which escapes is called hepatic, and it is the peculiar ingredient in the Harrowgate water, to which its smell is owing. Three parts of filings of iron, and two parts of sulphur, mixed, separate a similar gas, which is only hydrogenous gas, containing sulphur in solution.
