    amongst the former was 12’0, while amongst the latter it was 7*8. There were 111 convalescents who had not been on the Peninsula, and they had. all served in Egypt alone except 11 who had been at Salonica. Only 8 gave a previous history of dysentery, and no carriers were found amongst them, while the remaining 103 who had no history of dysentery yielded 4 carriers. These results are shown in Table IV.

In practically all these cases the entire stool was examined, and the character of the stool noted. The great majority of those described as blood and mucus were from cases of bacillary dysentery, while only a few (6T per cent.) were from cases of amoebic dysentery. In Table V given above the findings in the 961 cases tabulated are arranged according as to whether the stool was formed, unformed, liquid, or blood and mucus. In the latter case it does not necessarily mean that the stool consisted of nothing but blood and mucus, but that blood and mucus were present. In the majority, however, as these were cases of bacillary dysentery, blood and mucus were alone present, or formed the bulk of the stool in the manner characteristic of this disease. The percentages in the four columns show clearly that protozoa were most common in the unformed or liquid stools. It is, perhaps surprising that the encysted forms of E. coli and E. histolytica were more often found in stools of this kind than in the formed stool. As was to be expected, free forms of E. histolytica with included red blood corpuscles were only found in the case of the blood and mucus
