Catania, Sicily, 1895 __23 cases. 
Cases Xos. 58 to 80. — Venuti (1895) (referred toby Massari, 1898, p. 213) observed 
in the Reale Ospizio di beneficenza di Catania, 23 cases of Hymenolepis nana in 214 
boys examined. Most of these cases harbored a considerable number of worms, 
while in 100 boys of the general population belonging to diverse classes and in widely 
•differing conditions of life he could not find a single case. The lack of cleanliness 
among the inmates, the intimate association of some of those affected with worms, 
the appearance of subjective disturbances in others after they had been in the 
institution a certain length of time, ceasing rapidly after the expulsion of the para- 
sites, were circumstances which Venuti considered indicative of the occurrence of a 
direct contagion of endemic character.

Case Xo. 86. — The case of a little girl 21 years old is reported by Roder (1899) 
from the medical clinic at Bonn. 
The child is well nourished, the mucous membranes are perhaps somewhat paler 
than usual. The bowels are regular, and there is no apparent organic trouble. 
Until 4 months before, she had lived in Cologne. At 13 months she suffered from 
intestinal catarrh and cankered mouth, at 18 months passed an Ascaris, and at 2 
years had measles. After this she became pale, her appetite diminished, she grew 
dull and drowsy, blue rings appeared under the eyes, and she picked at the nose. 
Anthelmintics were administered, but no worms were seen. 
The patient was brought to the hospital and placed under anthelmintic treatment, 
August 19, 1897. Three 0.05 gram doses of calomel were given and the next morn- 
ing, after 80 grams of milk, 2.5 grams of ethereal extract of male fern, followed by a 
purge of castor oil, were given. In the stool which resulted, numerous eggs of 
Ascaris and eggs of Hymenolepis nana (3 to 4 in each preparation), but no worms 
were found. For several days following, eggs of Ascaris.^ but none of Hymenolepis',
