POISONING BY PHOSPHORUS.

From matches, rat poisons, fatal dose, horse, ox, pig, dog, chicken.

Symptoms: Anorexia, dysphagia, swelled tongue, thirst, colic, emesis,

vomit phosphorescent, or bloody, diarrhœa, icterus, agalactia,

trembling, weakness, choreic spasms, hemorrhages. Lesions:

Buccal-gastro-intestinal inflammation, fatty degeneration of

epithelium, liver, kidneys, heart and muscles, black blood,

ecchymosis, hemorrhage, phosphorescent ingesta. Treatment: Emesis,

stomach pump, oil of turpentine in mucilage.

Phosphorus is usually taken in the form of matches or more frequently as

one of the pastes sold for the destruction of vermin. Almost all of the

latter contain 1 to 2 per cent. of phosphorus, in combination with

flour, sugar, and fatty or oily matters. The lethal dose of phosphorus

is: Horse or ox 7 to 30 grains; pig 2 to 4 grains; dog ¾ to 1½ grain;

chicken ⅓ grain.

_Symptoms._ Anorexia, dysphagia, swelling of the tongue, intense thirst,

colic, emesis in vomiting animals, vomited matters may shine in the

dark, and may be tinged with blood, diarrhœa is common though not

constant, icterus, and suppression of the milk. Trembling, weakness,

acceleration of the pulse and breathing and hyperthermia may be noted.

Chickens have been noticed to have choreic movements in walking.

Hemorrhages are common.

_Lesions._ Inflammation of the mucosa of the alimentary canal from the

mouth to the stomach and intestines. Fatty degeneration of the

epithelium very noticeable in the gastric glands. Enlargement and fatty

degeneration of the liver and kidneys, and degeneration of the heart and

muscles. The blood is black and ecchymosis and hemorrhages appear on

various internal organs. The contents of stomach and bowels shine in the

dark. Phosphorus may be recognized by its luminosity when distilled at a

very low heat from an acid solution and received into a refrigerated

condenser. This must be done in perfect darkness, and the

phosphorescence will be seen in the condenser or connecting tube.

_Treatment._ Empty the stomach by emetic or stomach pump, and then give

oil of turpentine in mucilaginous liquid: Horse 1 to 2 ounces; ox 2 to 3

ounces; pig ½ ounce; dog 20 to 30 drops; chicken 5 to 10 drops. This may

be repeated several times and if used early enough will probably

succeed.
