In this paper a description is given of the bacteriologic observations for the stools and blood in a series of cases of psoriasis. For the most part the patients were in attendance at the dermatology division of the Cornell Clinic. A brief preliminary report on the intestinal flora in twenty of these cases has been published,1 but in the present communication the data for the complete series of thirty cases are given in detail. The purpose of this study was to determine if the intestine or blood during any stage of this skin disease might harbor bacterial or mycotic organisms of such a character as to suggest an infection, intoxication or sensitization of the skin from these sources. Although it cannot be said that our results have shed any positive light on the etiology of psoriasis, it seems worth while to put them on record in some detail,
