The most striking fact in the proving of Benzol seems to be the influence it had on the circulatory system. It caused a slowing of the pulse stream which in the guinea-pigs brought about the formation of infarcts. In the human provers it resulted in a decrease of the red and increase of white cells (R. F. Rabe, M. D). It ought to be of use in Leucemia. Eye symptoms striking. Hallucinations-Epileptiform attacks, coma, and anesthesia.

It seems to exercise a special influence on the nervous system and on the blood. Oxyhemoglobinemia. Physical weakness, cramps, exaggeration of knee jerks, nausea, vomit, dizziness, heaviness and coldness of limbs. Tremor of eyelids and tongue. Benzin, dinitricum--D. N. B.--(The most obvious results of poisoning by skin absorption are changes in the red blood corpuscles and liver degeneration in amblyopia, color-blindness, retinitis. Field of vision contracted.

Rolling of eyeballs in their vertical axis; pupils dilated. Nystagmus. Respiration very slow, difficult, sighing). Trinitrotoluene (T. N. T), Trotyl-is a high explosive, obtained by nitrating toluene-a product of coal tar distillation. When the skin or hair is exposed to T.N.T by contact a characteristic yellow or tawny-orange stain is produce, which lasts for some weeks. Indicated in graver forms of anemia (pernicious) and jaundice. Produces fatal toxic jaundice.
