rarely possible, although this may occasionally be done by close, persistent 
observation and study. 
The prognosis in multiple, inoperable, and septic abscesses is bad. In 
the solitary abscess which can be located, it is very good when the patient 
is in the hands of a competent surgeon. The treatment is surgical. 
Abscess formations in locations other than the liver are occasionally 
seen. They most commonly result from perforation and may occur 
anywhere in the region of the colon, from the rectum to the cecum. 
Perhaps the most common location is near the cecum where, if abscess 
can be diagnosed, operation offers good chances of recovery. These 
lesions vary greatly in size and often in their development involve impor- 
tant structures such as the peri-renal tissues, the psoas muscle, the 
appendix, the abdominal wall, and sometimes the kidney itself. Large, 
ischio-rectal abscesses may occasionally result from a perforation in the 
rectum and in one such case, which will be discussed below, a large 
quantity of amcebic pus was evacuated. Abcesses occurring along the 
descending colon may be of a dissecting type and cases may be seen at 
necropsy, where, owing to perforations, adhesions, and ulceration, the 
entire intestinal wall may have sloughed away leaving a continent 
channel partly formed by the abdominal wall and adjacent structures. 
In rare instances, small abscesses formed and held in place by adherent 
omentum may be encountered on the anterior surfaces of the colon. One 
found in the descending colon at autopsy contained about 20 cubic 
centimeters of pus. Abscesses have also been reported in the parotid 
gland, the floor of the mouth, the brain, etc. 
GASTRO-INTESTINAL COMPLICATIONS are very frequent and the after 
effects of dysentery on the upper portion of the alimentary tract are 
still more important. However, in the Tropics, a variety of disorders 
and diseases of this system are so frequently met with that it is very dif- 
ficult to determine just how specific the relation to ameebic infection is and 
just which of the various troubles are most dependent upon this specific 
parasitic infection. Ameebe are rarely found in the alimentary tube 
above the ileo-cecal valve, and it is probable that the majority of diseases 
encountered in this portion of the bowel are not in a direct way dependent 
upon the ameebe, but rather upon the associated dusturbing factors 
which so frequently attack the colon itself. In other words, the ameebic 
infection is usually a compound one and some of the symptoms in the 
colon and the majority of those above that portion of the bowel are due 
to agents other than the amcebe. Most of the gastro-intestinal complica- 
tions of amebiasis develop rather late in the disease and may more 
properly be considered as sequela, or after effects, but some should also 
-be mentioned here. 
Cancrum oris has frequently been pointed out as a complication in 
dysentery and it is occasionally seen in the amcebic variety; however, 
it is perhaps met with less frequently than in the catarrhal, Shiga, or
