Ringer and Murrell (*Lancet, November 3, 1883.-*C.D.P.) administered ten grains of *Na.ntrs., dissolved in an ounce of water, to fourteen men and four women. To twelve men and four women it was given in five-gr. doses. In almost all it produced alarming symptoms of the apoplectic order. A cat had 4 c.c. of a 10 per cent. aqueous solution injected under the skin, and dies of the effects. Collischorm (quoted *H.P., x. 469) related two cases of accidental poisoning with *Nat.nitros. (I) The first patient was affected with: Diarrhoea and fainting, bitter eructations, heavily coated tongue, and on the chest and eruption like syphilitic roseola. Traces of albumen in urine. During the night, copious alvine discharges with faintness. The following day, intense cyanosis. Urine dark yellow, containing copious urates. Next day he took 2.5 gr., cyanosis diminished and the measly eruption spread all over the body except the face. (2) The second patient had the cyanosis, diarrhoea, and faintings in an aggravated form so that collapse threatened. Strong Coffee and omission of the drug removed the symptoms. Worse Motion. Better Lying down. The concomitance of fainting with other affections may prove a keynote, “Copious liquid stools at night with faintness.”.
