The decomposition of the vegetable matter passed through three stages or degrees. The first gave off gases freely, yet of not so offensive odor as later. After ten days or two weeks the expense of securing inhalers was more than doubled, even for one moment of time. After three or four weeks not much gas was generated, for it seemed only capable of lying still and sending its fearful odor heavenward. Inhalation of the gases evolved produced for the first week or ten days a headache, nausea, distress in the stomach, coated the tongue white, and this in from one to two hours time generally; and there, if not carried too far, would generally pass off in two or three days. Inhalations after ten days or two weeks did not produce results in less than twelve or twenty-four hours, according to time and amount inhaled. Then there was fearful headache, nausea, aversion to food, distress through the hypochondriac region, first in the spleen, the liver and stomach, and on the third day chills that would doubtless have continued on indefinitely if not interfered with. After decomposition had gone on for three or four weeks it was ascetic and simply fetid to a fearful degree, and no results except nausea were apparent in any one exposed to it in less than three or four days. The first was extreme lassitude and loss of appetite, and apparently a continued fever, with an unlimited amount of pains and aches and a lassitude that limited locomotion. Three vials of the watery tincture were saved, one each from the various stages of decomposition, and from these an attempt was made to make provings and find out what were the reliable antidotes to them, and thus be able to cope with my invisible foe in my daily avocation. Their provings were not carried far enough, or continued long enough to be justified in placing them in our Materia Medica, but are ample to aid and guide the future steps that ought to be taken. Its discontinuance was rendered rather necessary by my enthusiasm that led too far in a few cases, but the antidotal effects of certain remedies amply compensated me for my financial and reputational loss. Bilious colic, nausea, cramps, diarrhoea and headaches were readily secured from a few drops of the first vial, in many cases, while the second vial gave me a large number of cases where the liver, spleen, stomach and kidneys were apparently seriously involved, and not them alone, but fair types of intermittent fever with its attendant shakes, some daily, some tertian. With the third vial trouble came, as it did reduce many that had been able to be up and around to their beds, and unmistakably cause them to get worse, and cause them to degenerate into a typhoidal or semi-paralytic condition. In a few cases I was deprived the liberty of finding my antidotes and helping them out of the dilemma.
