Leipzig slaughter-house, Echinococcus hydatida and Strongylus 
paradoxus , the lung nematode or swine. 
Of 5,156 swine raised in the country and slaughtered at 
Leipzig between May 1st, 1890, and April 30, 1891, 196 (or 
3.79 per cent.) were infected with echinococcus, generally 
(183 cases) in the liver. From September, 1890, to February, 
1891, 843 Hungarian swine were slaughtered and examined, 
181 (21.47 P cr cent.) of which were found infected. From 
May 1, 1890 to April 30, 1891, of 4,515 sheep examined, 591 
(^.opper cent.) contained hydatids. In the sheep, the para¬ 
sites were found more frequently in the lungs than in the 
liver (436 to 17,138 cases both lungs and liver), while in swine 
the parasite was more frequent in the liver. 
Heretofore E. multilocularis (racemosus ) has been considered 
a rarity, but Dr. Mejer states that he found it frequently in 
swine, once in sheep, and that 7 per cent, of all the echinc- 
coccus hydatids found in cattle were of this type. 
Strongylus paradoxus was found in the lungs of 19.03 per 
cent. (521 out of 2,212) German swine, and 52.02 percent. (426 
in 819) of the Hungarian swine. Dr. Mejer does not believe 
that this parasite harms its host except when present in 
immense numbers in young pigs.

Author believes he has experimentally proven that Echino- 
ococcns multilocularis is specifically different from E. unilocularis 
\polymorphus, hydatidosus). As specific difference of the tape¬ 
worm, he gives the size of the hooks as larger in E. multi¬ 
locularis than in the common form, i. e. y hook 19-18 ; 16, base 
10: 7. 
These differences in the size of the hooks might possibly be 
varietal if found constant, but 1 have very grave doubts as to 
whether the author is justified in calling them specific.
