    polypoid adenomatous tumours. Near the anus these polypoid tumours bear some resemblance to ordinary haemorrhoids, but within the gut, and especially be- yond the internal sphincter, they differ materially from these latter. In the first place, in a given area they are infinitely more numerous than piles ever are; and, instead of being rounded and smooth like haemorrhoids, their surface is velvety, from thicken- ing of the mucous membrane itself, and the outline is broken up in all directions by the formation of secon- dary polypi, growing from their own surface and branching in all directions, until the larger and fully- developed tumours bear a great resemblance to red branching coral. These tumours extend high up in the rectum beyond the reach of the finger, and this is so invariably the case that it would suggest the idea that the affection of the rectum begins from above, in the neighbourhood of the sigmoid flexure, and pro- ceeds downwards. (Milton.) As in other parts of the intestinal tract, stricture of bilharzial origin is never found in the rectum. In the lower part of the rectum, the most common seat of intestinal bilharziosis, the symptoms are those of tenesmus, with an irritative diarrhoea and the passage of thick glairy mucus and blood. Very often mucus and blood are passed without any faecal matter at all, and the straining may be almost continuous, and the tenesmus very severe, especially if pendulous masses are protruded from the anus and caught by the sphincter during defaecation. This also increases
