16, 1 Haughwout and Horrilleno; Intestinal Parasites 15 
Unless otherwise noted, the column devoted to abdominal 
symptoms records the symptoms observed by the patient or those 
with whom he lived prior to the onset of the disease that led 
to his being brought to the hospital. So many of the children 
included in this series were suffering from diseases of the 
alimentary tract, that in themselves give rise to more or less 
positive abdominal symptoms, that it was realized that this 
distinction must be drawn. 
Symptoms referred to the nervous system presented some 
difficulty; but we followed the same general rule, eliminating, 
so far as we could, all phenomena clearly referable to some 
condition other than parasitism. We realize that we may not 
have been entirely successful in our treatment of this factor, but 
we have done the best we could under the circumstances. 
When it came to collecting information as to the vomiting 
or passage of worms before the patient was admitted to the 
hospital, we had to rely largely on the statements of parents or 
others with whom the child lived; but we have felt perfect secur- 
ity in so doing, for it would probably not be easy to find a Fili- 
pino mother who did not know a round worm when she saw it. 
In all cases where reference is made in the table to the passage 
or vomiting of worms, it should be understood that the worm 
to which reference is made is Ascaris lumbricoides. 
The youngest group of children is recorded in Table 9. With 
the exception of cases 46 and 56 none showed abdominal symp- 
toms of any importance. Case 46 was infested with four para- 
sites; while case 56, which showed the most marked symptoms, 
was rather lightly infected with Trichuris. Case 87, which was 
infected with Ascaris, had never, so far as we could ascertain, 
shown symptoms referable to the abdomen or the nervous sys- 
tem. The infection was light and, as has been said, was 
detected on the second concentration of the stool. 
Case 46 had been breast-fed from birth to the time of ad- 
mission, but after the eighth month the mother reénforced its 
diet with bread and rice. Case 56 had been bottled-fed since 
birth. We were unable to obtain reliable data on case 87. 
With the exception of case 63, which had been given other food 
from time to time, all the children had been breast-fed from 
birth to date of admission. 
One of the most interesting cases in Table 10 is No. 83, a 
2 year old girl who was admitted for treatment of an acute 
bronchitis. This child was infected with “Blastocystis,” Endo- 
limax nana, Trichuris, and Ascaris. The physical development 
of the child was only fair. She was abnormally quiet and, not-
