    acetone, methane, snlpliureted liydrogen, and ammonia. The cause is nsually bacteriah The fermentation of carbohydrates produces lactic, but}Tic, and acetic acids, and possibly also hydrogen; furthermore, as the result of yeast fermentation, alcohol and carbonic acid are produced. The putrefaction of albuminoids results in ammonia, sulphureted hy- drogen, and methane. Rosenheim and Strauss * have shown that traces of ammonia may occur normally in the stomach ; carbonic-acid gas may also be regarded as a normal product in the stomach. The relations of sulphureted hydrogen have been studied by Boas and Zawadski.f Boas claims that this gas occurs especially in dilatation of the stomach due to benign stenoses, and that it is not found when the cause of the pyloric stenosis is malignant. It occurs even when HCl is present in normal amounts. Zawadski only found it when the stomach contents had stagnated over 24 hours. It may readily be detected by its characteristic odor of rotten eggs, and also by the blackening of a strip of filter paper moistened with alkaline sugar-of-lead solution, which is hung in a well-corked test tube containing some of the stomach contents. The occurrence of this gas and of methane will be discussed in Chapter YI, where the subject of fermentation and putrefaction will be considered in detail. It is to be noted that Betz and Sena- tor have found HgS in acute gastric catarrh, and Emminghaus has observed it in a case where there was a communication between the stomach and the perforated intestines. Acetone has also been found in stagnating stomach contents by Yon Jaksch and Lorenz ; :j: these writers also claimed to have found it in other conditions. Penzoldt and SavehefE * maintain that they have never been able to find it. Ptomaines have also been extracted from stagnating stomach con- * [Rosenheim. Centralblatt fiir klin. Med., 1893, No. 32.
