vals during the two weeks preceding the above date. Up to the time of the report 
no marked emaciation had occurred; the appetite was less fitful, and the vision more 
perfect, but the pain in the head had not much abated. 
Buenos Ayres, Argentina, 1886 ? 1 case. 
Case Xo. 92. — According to 0. Werxicke (1890, p. 351), Dr. Eoberto Wernicke, in 
1886, observed in the feces of a little girl cestode eggs, which he was miable to 
identify as belonging to any species known to him. He administered a vermifuge, 
but did not succeed in finding any worms. After seeing the eggs from 0. Wernicke’s 
case (1890), Dr. E. Wernicke exj^ressed the opinion that the eggs found by him in 
1886 were of the same species. 
Buenos Ayres, Argentina, 1890 1 case. 
Case Xo. 93. — Werxicke (1890) found 30 to -^0 oi Hymenolepis nana in 
the intestine, at the autopsy of an Argentine sailor, aged 28 years, who had died of 
pulmonary tuberculosis. This case was also- reported and the specific determination 
confirmed by Blaxchard (1891a). 
Sao Paulo, Brazil, 1893-1891 2 cases. 
Lutz (1894) reports two cases of Ilymenolepis nana, also a case of Hymenolepis dim- 
inuta. (Seep. 98. ) 
Case Xo. 94- — The first case was that of a 21-year-old girl who had shown symptoms 
of nervous and intestinal troubles for about a year. Several times she suffered from 
irregular attacks of fever, and showed other symptoms common to the teething period. 
Ascarids were j)assed on several occasions. During one of the attacks of fever the 
feces were examined; encysted flagellates and eggs of Trichiiris and of Hymenolepis 
nana were found. After the fever had subsided, a treatment with ethereal extract of 
male fern resulted negatively. A second attempt Avas made with freshly obtained 
extract in three doses of 0.3 gram each at intervals of two hours, and in the stool after 
the first dose 5 strobilae, Avithout recognizable heads, Avere obtained. There AA as a 
slight improA^ement for a Avhile, but the former symptoms of abdominal pain, diar- 
rhea, restless sleep, and jiained expression of countenance, soon returned. Male 
fern Avas again administered in a 3-gram dose, and about 100 Hymenolepis^ 15 of 
them Avith heads, and 2 female Trichurls Avere expelled. Tavo Aveeks later the child 
was much improA’ed, but not entirely Avell. 
Case Xo. 95. — The second case Avas a 4-year-old girl, born in Sao Paulo, of foreign 
parents. She had suffered for tAvo years Avith continual diarrhea and intermittent 
attacks of fever. Carefully regulated diet and treatment in Europe, had had no 
ameliorating effect. There Avere symptoms of perverted appetite, eating of plaster 
from the Avail, etc., Avhile the nervous symptoms Avere little pronounced. Contrary 
to what one Avould expect from the length of time the trouble had lasted, the nutri- 
tion had not suffered to an appreciable extent, a circumstance due perhaps to the 
care Avhich the girl had received. After the discoA’ery of eggs of Hymenolepis nana 
in the feces 4 grams of ethereal extract of male fern in emulsion Avere administered, 
and tAVO passages containing an enormous number of worms occurred. In an incom- 
plete enumeration, 0A*er 2,000 indiA'iduals were counted, of which about 10 per cent had 
heads. Little chains of ripe segments AA^ere also common. About three Aveeks later, 
the extract Avas again giA'en, in a dose of 2.5 grams, and 25 Avorms Avere passed. All 
symptoms of the former trouble disappeared, and while previously the diarrhea had 
persisted in spite of all carefulness in diet, the stools became normal and so remained, 
although the girl noAV ate anything she pleased. 
Galveston, Tex., 1902 1 case. 
Case.Xo. 96. — Moore (1903) « has reported a case of II. nana from Texas, in a pre- 
liminary note read recently before the University of Texas Medical Club.
