It is evolved when animal or vegetable tissues containing Sulphur decays; and it also occurs in mineral springs, being liberated by the reduction of gypsum or other sulphates through the action of a microbe (Cent. Dict.). Sul. h. is one of the agents which give rise to "blood poisoning" when bad smells are encountered. Asphyxia, tetanus, delirium, low continued fever have been observed as resulting from the gas J. Wiglesworth (B. M. J., July 16, 1892) has recorded two cases of insanity, one certainly, and both probably, due to inhaling the gas: R. H., 32, engineman at chemical works, had been kept at home with an attack of bronchitis for ten days. A few days after his return …
