protozoa, and no Blastocystis, were found. Case still being treated for 
malaria. No records obtainable of bacteriological examinations. 
Case D. 5.—Soldier, native of New Zealand. Has suffered ever since 
adolescence from “bowel troubles”—constipation alternating with 
diarrhoea—accompanied by abdominal pains. Treated several times in 
New Zealand for “inflammation of the bowels.” Had an attack of 
“dysentery” when in tropics on troopship to England. Attack lasted a 
few days, and he recovered without treatment. After a short stay in 
England went to France in June, 1917, where he contracted acute 
dysentery in August, 1917. After one month in base hospital in France, 
entered a general hospital in England as a dysenteric convalescent. 
Examined by us here four, times. Dientamoeba being found on three 
occasions. Entamoeba coli the only other protozoon found. Three 
bacteriological examinations made at the same time all negative. 
Dysentery has disappeared, but patient still suflers from his original 
intestinal irregularity. 
Case D. 6.—Soldier, native of New Zealand. History closely similar 
to that of case D. 5, differing only in that he had no dysentery on troop¬ 
ship to England, and only a slight attack in France. Examined by us 
twice only on his return to England convalescent. Dientamoeba being 
forxnd once. Also infected with Entamoeba coli, but no other protozoa 
found. Three bacteriological examinations in England all negative. 
Patient, having recovered clinically, has now been discharged. 
Case D. 7.—Soldier, native of New Zealand. Before enlisting in 1914 
had suffered from attacks of dysentery, recurring every few years, for 
about 20 years. Attacks severe, lasting three or four weeks, much blood 
and mucus being passed. Recovered on each occasion after rest in bed, 
without specific treatment. No causal organism ever found. Similar at¬ 
tacks on troopship to England, and in France, 1917. Returned to a general 
hospital in England, as dysenteric convalescent, September, 1917. Here 
examined by us seven times during September, October and November, 
Dientamoeba being found on one occasion only. Case also infected with 
Entamoeba’’'’ nana. Four bacteriological examinations of stools all 
negative. Patient has now recovered clinically, and his stools are normal.
