discovered in the first preparation, but no other animal parasites 
were ever found. He had a light Blastocystis infection. 
I questioned the patient and learned that he was taking the 
equivalent of 90 grains of ipecac daily. This led me to suspect 
that much of his, trouble was due to the ipecac. I therefore 
told him to discontinue taking the drug, for I saw no indication 
for continuing it, and within twefity-four hours his fseces had 
become formed. 
The patient did not report to me again until March 12, at 
which time he passed a hard, formed, rather dry stool. Micro- 
scopically, the stool contained rather numerous cysts of 
Isospora, Blastocystis, and a few Charcot-Leyden crystals of 
the short form. Parenthetically it might be mentioned that 
Noc, (12) who has recently reported a case of infection with this 
parasite, which I shall discuss later, found in the stools of 
his patient some crystals in the form of elongated lozenges 
( losange allonge) which he believes were fatty-acid crystals. 
These, I am inclined to believe, may have been Charcot-Leyden 
crystals. As a check, one of the cysts was measured and was 
found to be 26.6 n in length by 14.9 ^ in breadth. 
On March 15 the patient came to me again and passed a light, 
yellowish brown, soft-formed stool at the laboratory. The cysts 
were much more numerous than before. The following day 
the patient passed another stool at the laboratory. This con- 
sisted of two distinct portions — an apparently normal, formed, 
brown mass and a greenish brown, bile-stained and very soft 
portion passed after it. Cysts were very numerous. 
On this day (March 16) the patient looked ill and anxious. 
On my instruction he had been eating carefully and avoiding 
all food that would have a tendency to lay stress on his intestinal 
tract. He seemed to suffer no actual pain, but he complained of 
a dull, dragging sensation in the abdomen and slight nausea at 
times. 
He was no better when he next visited the laboratory on 
March 21. The stool passed that morning was light yellow and 
again consisted of two portions — a solid portion and one, passed 
after it, that was very soft to watery, verging on diarrhoea. 
It, also, contained numerous oocysts of Isospora. Microscopi- 
cally, I found numerous strands of mucus containing epithelial 
cell debris, but no blood nor pus. The stool certainly was not 
dysenteric in character, but it showed unmistakable evidence of 
a morbid process somewhere in the intestinal tract. I carefully
