Limulus cyclops. L. polyphemus. Polyphemus occidentalis. King-crab. Horse-foot. Sauce-pan. (Coast of North America). N. O. Merostomata, or Poecilopoda of the Crustacea. Triturations of the dried blood.

Clinical.-Apoplexy. Cholera. Constipation. Diarrhoea. Fever. Haemorrhoids. Sea-bathing, effects of. Skin, affection of.

Characteristics.-Limulus was proved in the lower triturations by Hering, Lippe, and others. Among the symptoms recorded the most notable was a rush of blood to the face, with heat of face and over whole body, recalling a similar symptom of Ast. r., another sea-animal. The remedy does not appear to have been much used, and Hering has omitted it from his Guiding Symptoms. The only italicised symptoms in Allen are these: "Frequent rush of blood to the face, and painful fulness of the whole right half of the body, especially here and there, and in the lower extremities" (a symptom of Hering's from the first centesimal trituration); and "heat, burning, and constriction in abdomen" (Blumenthal, a grain of 1st trit). There was much gastro-intestinal disturbance, and in one prover a choleraic condition. Headache caused by straining at stool. The flushing of the face was < in afternoon. There was dyspnoea < by drinking. Coryza < drinking cold water. Heat in face alternated with confusion in head.

Relations.-Compare: Homarus, Ast. r.; Fer. (flushing); Indium. (pains in head from straining at stool); Ars. (ill-effects of sea-bathing).
