anthelmintic treatment, she passed, besides a Tsenia solium, 2 specimens of Hymeno- 
lepis diminuta, measuring 25 and 30 cm., one of which possessed a head. 
In the second case (Grassi, 18881, p. 500, Grass: & Rovelli, 1888b) infection was 
induced experimentally by feeding a man with cysticercoids (see p. 95). 
Pisa, Italy, 1895 1 case. 
A specimen of tapeworm, which had been passed by a boy in September, 1895, 
after the administration of an anthelmintic, was referred to Sonsino (Sonsino & 
ZscHOKKE, 1896) for determination by Doctor Modigliano, of the Pisa hospital. 
Sonsino determined the specimen as Tsenia flavopunctata Weinland (=iA diminuta). 
Zschokke made a similar determination. The description of the worm and the 
figure of an egg given by Sonsino leave no doubt as to its identity. 
Centuripe, Sicily, 1900 2 cases. 
Previtera (1900) discovered in the feces of sulphur miners in Sicily the eggs of a 
tapeworm, undoubtedly of the species Ilymenolepis diminuta. 
The first case was that of a sulphur miner, male, 11 years old. There was an 
average of one egg in every j^reparation. The eggs were mostly spherical, almost 
double the size of eggs of Ticnia solium; two membranes were present, separated by 
an abundant hyaline substance which shriveled in glycerine and drew away from 
the outer membrane; the latter was distinctly striated radially; some of the eggs 
were uncolored, some yellowish. Male fern was administered. Whether any worms 
were passed is not known, but a reexamination of the feces some days later showed 
no eggs present. 
In the feces from the other case 2 to 3 eggs were found in every preparation. The 
subject of this case was not seen, no" was any information regarding his age, jihysical 
condition, etc., obtainable.
