EXTRACTS FROM FOREIGN JOURNALS. 
discover a relatively large proportion trichinae, and this de¬ 
spite the enforcement of the Act of March 3d, 1891, which 
provides for the microscopic supervision of meats intended 
for export trade. The same report has been rendered from 
the cities of Dusseldorf, Crefeld, Emmerich, Bremen, Leipzig, 
Altona, Posen and Koblenz. 
It consequently becomes of immense import to the sanitary 
police to determine if the micro-organism is annihilated by 
the process of pickling through which the meat is conserved. 
Many experiments upon this point have been carried out, but 
few positive results have been obtained. Mice, rats, rabbits, 
cats, young swine and guinea-pigs have been the animals used 
in these trials. 
Thickly settled swine meat was fed to rabbits with nega¬ 
tive results by Hintzen of Cleve, Ernst of Hildesheim, 
Schenk and Wagner of Frankfurt-a-M., Frankel and Klap- 
hake of Crefeld ; flesh of the same character was fed by Wag¬ 
ner, Schenk and Janssen to cats, pigs, mice, rats and guinea- 
pigs also with negative results. 
Experiments instituted by the Imperial Health Bureau 
also terminated adversely. Hertwig and Johne have found 
living trichinae in American meat (supposed to have been in¬ 
spected at the port of departure in the United States). Dunck- 
er in Dresden and Untersuchen in Hamburg have acquired 
positive results by feeding the flesh to rabbits.* 
In modern times Janssenf has also secured positive results 
by feeding the affected meat to a rat for twenty-one days. 
At the end of this time the rodent was killed, and three well 
developed and sexually mature intestinal trichinae were ex¬ 
posed—two females and one male. In the former numerous 
eggs could be discerned, but no embryos. 
On the 27th of March, 1892, Supervising Veterinarian 
Grosswendt delivered to the pathological institute samples 
of American pork which were so thickly overrun with the 
parasites that in 0.1 grammes of the same six trichinae were
