Dr. Marcet made many observations on the treatment of this condition, and published a special essay to illustrate the value of zinc oxide in controlling the unsteadiness and the tremor which are its usual accompaniments ("Chronic Alcoholic Intoxication," London, 1860; Lancet, i., 1859). Dr. Anstie accorded some, but not so much, value to the drug in the same conditions.

In Hysteria and Debility, if anaemia be not extreme, zinc salts often prove useful, but more especially when combined with other nerve-tonics: thus, Dr. Barnes speaks very favorably of zinc with phosphoric acid (phosphate of zinc) (Lancet, i., 1858, p. 119), and has recently re-stated his opinion as to its value in convulsive diseases of women (Lancet, i., 1873, p. 621). Vigier finds the phosphide of zinc acts more quickly than phosphorus itself (Bulletin, January, 1876), and the valerianate, although decried by many observers, certainly relieves in some cases. Zinc oxide may be combined with camphor, galbanum, sumbul, etc.
