Dr. Black (Torquay, England) publishes all the known provings, and in addition some very thorough ones conducted by himself; from these we select the following striking symptoms: Proll experienced a sensation as if a large spider were crawling over his hands; a glow rising from feet to head, and he seemed to be on fire, though his face was pale, this repeatedly; also violent aching pain in right foot recurring frequently. Proving with the tincture in increasing doses up to 40 drops. Two women took the drug to produce abortion; every muscle of the body was paralyzed, including bowels, save those of the eye, and both died on the 8th and 9th day, starved to death. The provings by Dr. Black. A well-built woman, aged twenty, took repeated doses of the drug from [Greek: theta] up to 30th. The most striking symptoms were: Sudden, severe thumps of the heart that then went on beating at a tremendous rate; it slowed down and was followed by trembling in the limbs; after this was very marked jerking of the limbs, and twitching; hot feeling, though not actually hot. "A feeling as if I should bite some one if I did not keep my teeth clenched. A wretched feeling as if I should do something awfully wrong if I did not keep myself under control." Several months later the effect of the drug was still strongly in evidence; "thinks she will go out of her mind, feels as if she would have an epileptic fit, says she would feel far happier in an asylum." A second prover, Mrs.---- æt 37, experienced jerking and twitchings of the muscles, shooting pains in left ovarian region, and, on movement, lumbar pain and stiffness. Proving made with 3d dilution. Third prover, æt 27, a woman. First marked symptom was a shooting pain in left ovary; then pain and twitching in leg, when aching stopped it felt very hot; aching repeated, and only relief was shifting the position of the leg to a cool place in the bed; again a dreadful pain in the region of the left ovary--"a fearful aching" "it was a pain you couldn't have put up with long without doing something;" later: "I have had no pain, but a great twitching in my hands and legs for a long time, just like a person with chorea--first my left hand jumped, then both legs, my heart seemed to beat very fast." "When hands were held it seemed to alleviate the jerking and twitching." The pain in ovaries, also in other parts of the body at times, the twitchings and jerkings, and the frequent hot feeling continued during all the proving. It was made with the 3d and [Greek: theta]. The fourth proving was made by Dr. Black himself, chiefly with the 3x and [Greek: theta].
