_Antidotes._ The great indication to be fulfilled in a case of this description, is the ejection of the salt by vomiting. _MM. Orfila_ and _Berthollet_ rely very confidently upon the effects of _bark_, _strong tea_, _infusion of galls_, and other _vegetable astringents_, which have undoubtedly the power of decomposing the salt. They ought, therefore, to be employed as diluents to assist vomiting, but they are not to be considered as antidotes which can render this latter operation less indispensable. _Physiological action of emetic tartar._ _M. Majendie_ has shewn by experiment, that if _tartarized antimony_ be injected into the veins of a dog, the animal vomits, and has frequent stools; his breathing becomes difficult; his pulse frequent and intermitting; a great degree of disquietude, and tremblings are the precursory signs of death, which generally takes place within the first hour from the injection of the emetic tartar. On opening the body great alterations are perceived in the lungs; they are found of an orange or violet colour, have no crackling, are distended with blood, and of a tight texture. The mucous membrane of the intestinal canal, from the cardia to the extremity of the rectum is red, and strongly injected. If, instead of thus injecting the emetic tartar into the veins, it be injected into the stomach, and the œsophagus is tied to prevent vomiting, _M. Orfila_ informs us that the same alterations will be found after death. The very same effects will also arise from the application of the emetic tartar to the different absorbing surfaces, such as the cellular substances, &c.
