stool specimen Wes examined per person. Cartons
were distributed in the evening with the request
that specimens be brought in the next day ut
any time. Asa result, most speciinens were exantined within an hour after being passed. Ege
counts Were made on the Beaver preparations,

The Rongelapest dress ax the Americuns do tn
the same chimute, with the exception that a
higher percentage of them go barefoot They eat
flour, rice and canned foods in addition to fish,
eluins and other molusks, Local vecetable foods
are limited to eoconuts, taro tubers, breadfruit
and pandanus fruit. Phe istanders appear to be
well fed and generally are in good health. The
normal pattern of activity of these people,
which is concerned with coconut cultivation and
fishing, had been disrupted by the events of the
past few years. At the time of the survey they
had not vet entirely gone back to their usual
activities.
Although, as mentioned above, privies are
available around the houses in the village, it is
prohable that defecution is commonin the brush
by both children and adults. The practice of
morning defecation on the beaches belaw the
high-tide line appears to have disappeared
among the Rongelapese.
MATEREALS AND METHODS
The proceedures used for stool examinations
Were direct ¢xaminatious of suline mounts, using
exposed) populitions was close euough to be
considered the sume. There were more infections
with small race Enftamecba histolyfica and with
hookworm in the nonexposed group, ancl nrore
infections with Trichomonas hominis in tho exposed group. For the three major pathogens
found the over-all infection rates were: i, fitstalytica, $8.26); hookworm, 3.400. Trichuris
trtchiura, 34.547.
Of the 69 exposed individuals, 40 had eosina-
phile counts of 5° or more, and 29 had counts
of less than 3¢¢. Amone the nanexposed individuals, there were 60 cases on whom both stool
examinations and costnoplite counts were availTABLE 1
