TRICHINIASIS OF MAN AND ANIMALS. 17 



the person who died, consumed, raw, a piece of pork known to be 

 trichinous, in order to show that the idea that trichinae caused dis- 

 ease in man was a fallacy. Of examinations of American pork, the 

 report says 3,030 trichinous pieces, sides, were found. Such an 

 examination has no statistical value, as it does not show whether 

 the sides were all from different hogs or not ; further, were they all 

 American ? The average of trichuriasis in American pieces, not 

 hogs, was found to be 4: to 100. It was found that the abdominal 

 muscles were only serviceable for examination, or such as were at- 

 tached to the shoulders. More than twenty sides a day should not 

 be examined by one person (?). 



In Schleswig, of 782 " Amerikanischen Eouladen," 8 were found 

 trichinous ; of 1,952 sides, 61 ; 3,903 hams, SQ ; and 13 shoulders, 3. 



In Stettin, of 72,230 sides, 1,121 were found trichinous. 



The number of swine affected with measles was 1,710 more 

 than in the former year. 



From Hamburg, Germany, we have a few statistics which may 

 have an instructive comparative value : 



In 1878, of 35,510 American hams examined, 397 trichinous. 



" " 14,003 " sides " 85 " 



" " 17,113 European hams " 3 " 



" " 222 " sides and 10,838 hogs examined, none trichinous. 

 In 1879, of 79,864 American hams examined, 1,087 trichinous. 



" " 22,749 " sides and shoulders examined, 196 trichinous. 



" " 28,710 European hams examined, 2 trichinous. 



" " 16,204 " hogs " 1 " 



In 1880, of 55,008 American hams examined, 566 trichinous. 



" " 23,589 " sides " 270 " 



" " 49,943 European hams, sides, and hogs examined, none trichinous. 

 At Blankenburg, from 1864-'65, 7,000 to 8,000 hogs examined, and but 1 in- 

 fected. 



At Hanover, from 1865-'66, 18,656 hogs examined, and 12 trichinous. 

 In Sachsen- Weimar, from March, 1868-'69, 19,611 examined, and 1 found 

 trichinous. 



In 1875-76, at Frankfort, 8,000 hogs examined, 4 trichinous. 



" " Gulen, 1,600 to 1,800 hogs examined, 1 trichinous. 



At Copenhagen, 1867, 8,174 examined, 15 trichinous. 

 At Charkow, Russia, 1876, 3,550 examined, 5 trichinous. 



These statistics could be multiplied ad libitum, but they are 

 sufficient to show the results of Continental examinations. It is to 

 be regretted, however, that we have no reliable statistics from either 

 England, Scotland, Ireland, or France, or other Continental coun- 

 tries, since they have commenced to lay so much stress upon the 

 infected condition of American pork,
