vive 140° F. Hams thoroughly smoked or salted for three 

 months are safe. Slightly smoked hams and those steeped 

 in creosote or carbolic acid are most dangerous. Pigs should 

 not be kept near slaughter-houses, and especially should the 

 waste of these places be forbidden them. Such hog-pens, 

 indeed all piggeries, should be kept scrupulously clean and 

 clear of rats and mice. ■ The carcasses of swine fed near 

 slaughter-houses or where rats abound should be subjected 

 to a thorough microscopic examination before passing into 

 consumption. Whenever a case of trichinosis occurs in a 

 human subject the pork should be traced to its source if 

 possible, and the pigs reared in the same place killed and 

 subjected to prolonged boiling. The rats and mice should 

 be eradicated and the hog-pens and manure burned.
