yals 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. Wernicke (1890, p. 351), Dr. Roberto Wernicke, in 
1886, observed in the feces of a little girl cestode eggs, which he was unable 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 fromO. Wernicke’s 
case (1890), Dr. R. Wernicke expressed the opinion that the eggs found by him in 
1886 were of the same species. 
Buenos Ayres, Argentina, 1890 1 case. 
Case Xo. 93 . — Wernicke (1890) found 30 to 4:0 specimens ot IlyrnenolejJis nana in 
the intestine, at the autopsy of an Argentine sailor, aged 28 years, who had died of 
pulmonary tuberculosis. This ease was also reported and the specific determination 
confirmed by Blanchard (1891a). 
Sao Paulo, Brazil, 1893-1894: 2 cases. 
Lutz (1894) rej:>orts two cases of Hymenolepis nana, also a case of HymenoJepis dim- 
inuta. (Seep. 98. ) 
Case Xo. 94 - — The first case was that of a 2 J-y ear-old girl who had shown symptoms 
of neiAmus 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 passed 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 was 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 strobilse, without recognizable heads, were obtained. There was a 
slight improvement for a while, but the former symptoms of abdominal pain, diar- 
rhea, restless sleep, and jiained expression of countenance, soon returned. Male 
fern was again administered in a 3-gram dose, and about 100 Hymenolepis, 15 of 
them with heads, and 2 female Tnchuris were expelled. Two weeks later the child 
"was much improved, but not entirely well. 
Case Xo. 95 . — The second case was a 4-year-old girl, born in Sao Paulo, of foreign 
parents. She had suffered for two years with continual diarrhea and intermittent 
attacks of fever. Carefully regulated diet and treatment in Europe, had had no 
ameliorating effect. There were symptoms of perverted appetite, eating of plaster 
from the wall, etc., while the nervous symptoms were little pronounced. Contrary 
to what one would 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 which the girl had received. After the discovery of eggs of Hymenolepis nana 
in the feces 4 grams of ethereal extract of male fern in emulsion were administered, 
and two passages containing an enormous number of worms occurred. In an incom- 
plete enumeration, over 2,000 individuals were counted, of which about 10 per cent had 
heads. Little chains of ripe segments werq also common. About three weeks later, 
the extract was again given, in a dose of 2.5 grams, and 25 worms were 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 now ate anything she pleased. 
Galveston, Tex., 1902 1 case. 
Case Xo. 96 . — Moore (1903) « has reported a case of H. nana from Texas, in a pre- 
liminary note read recently before the University of Texas Medical Club.
