In a memoir relating to Thallium, the author calls the attention of the academy to the danger that may be apprehended from dealing with such a powerful poison. The Sulphate is an energetic poison, the two principal symptoms of which are the *pain in the stomach and bowels, consisting of terribly severe lancinations, following each other with the rapidity of electric shocks; second, the trembling and more or less complete paralysis of the lower extremities. These symptoms, associated with constipation, retraction or depression of the abdomen, complete loss of appetite, represent a marked analogy to the phenomena of lead-poisoning
