Mygale Lasiodora mygal.

Mygale Lasiodora Cubana. A large black Cuban Spider. N. O. Arachnida. Tincture of living spider.

Chordee. Chorea. Gonorrhœa.

The pathogenetic data of Mygale consist of a proving by a young lady and the effect of a bite on a man. In the latter case, inflammation ensued which spread along the lymphatics, violet and afterwards green discoloration; chill followed by fever, dry mouth, and great thirst, trembling, dyspnœa, despondency, and fear of death. The prover developed sadness; dry mouth; nausea with great palpitation, dim sight, and great general weakness; increased flow of urine, hot, scalding, with stinging in urethra. This last symptom has led to the successful use of Myg . in gonorrhœa, chordee, and syphilis. The "trembling" observed in the man suggests its use in nervous cases, but the sphere of Myg . in chorea has been developed from the clinical side. In the cases cured with it, twitching and contractions of facial muscles have been very prominent; convulsive movements of head to right side; twitching of one side of body, mostly right. The twitchings may be so violent as to prevent walking. Limbs are quiet during sleep, movements < in morning. Nausea with strong palpitation should be an indication. Symptoms < by eating. < Sitting (legs in constant motion).
