The types of compounds detected during the study (3, 4, 8)were carboxylic acids, hydroxy acids, alcohols, and amines. The carboxylic acids were extracted as previously described (4) with nanograde chloroform from acidified watery diarrheal stools that had first been centrifuged to remove particulate matter. Formed stools were first made watery by the addition of 9 ml of distilled water to 1 ml of stool; then they were processed in the same way as watery diarrheal stools. The carboxylic acids were derivatized as previously described (1, 4) with trichloroethanol (TCE) and heptafluorobutyric anhydride (HFBA). TCE derivatizes only the carboxylic
