36 THE DISEASES OF DOMESTIC ANIMALS. 



tion of the pork at the house revealed the presence of numerous 

 trichinae. 



Thudicum * suras up the principal phenomena of trichiniasis in 

 man as follows : " Sudden swelling of the face, particularly of the 

 eyelids, after the patient has for some days felt prostrate and lost 

 his appetite — the swelling causes only a sense of tension, but no 

 pain — fever, quick pulse, copious perspiration, which not rarely has 

 a repugnant odor ; painf ulness and immobility of the arms and legs ; 

 the muscles are swelled and contracted, and give great pain on being 

 moved, or pressed severely ; in the worst cases the entire body is 

 perfectly immovable and highly sensitive ; there is diaiThcea, with a 

 red, somewhat coated tongue, inclined to dryness ; when the swell- 

 ing of the face has subsided, oedema of the feet, legs, and thighs 

 comes on. Shortly afterward anasarca and swelling over the trunk 

 makes its appearance." 



From the time of Zenker's case, numerous others have come to 

 pass in different countries, and epidemics have caused a shudder of 

 horror among reflecting people. 



Epidemics have been reported at Corbach, 1860 ; Plauen, 1861- 

 '62; Calbe, 1862; Hallstadt, 1862-'63 ; Hanover, 1864 ; Dresden, 

 1864 ; and other places in Germany. The most remarkable outbreak 

 is that of Hedersleben, a place of some two thousand inhabitants, 

 of whom 337 became sick at one time, and 101 died. 



Cobbold communicated to Heller that the first authentic case of 

 the disease, during life in man, occurred in England in 1871. 



"We have mentioned several cases illustrating the intra-vital dis- 

 covery of the parasites in human beings on the excision of tumors, 

 and numerous others are reported in medical literature. 



Forty persons became infected with trichinos at one time at 

 Bremen from, it is said, eating American pork. 



At Lissa,f five members of one family became infected from 

 eating of a ham which, it was said, had been pickled, smoked, and 

 boiled for two hours. 



A poor woman ;{: became trichinous from eating the flesh of a 

 dog, to which her necessities had driven her. 



At Linden,* a suburb of Hanover, four hundred persons were dis- 

 eased at one time, and twenty-one died from eating trichinous pork. 



Dr. Keifer, |! of Detroit, reports a fatal case of this disease, the 

 patient dying at the end of the fourth week.
