enclosed in the farmyards of their breeders, are free from worms which are likely to live in the body of man. The Irish pig is the one most commonly injured by entozoa, and the reason for this is evident when we know how much the cottager relies on rearing a porker which is permitted the free range of house and road, where every description of filth is devoured, charged with the ova of parasites expelled by man or some of the lower animals.” He also adds: “The conditions under which we live in the British isles are certainly much less favorable to the propagation of worms; but we disregard, in our ignorance, the most common precautions to protect ourselves from loathsome diseases, and not only permit dogs to eat any kind of offal in and around slaughterhouses, but sanction the existence of piggeries where all kinds of garbage, charged with worms or their eggs, are daily devoured by swine. The majority of germs calculated to engender parasites are to be found in abundance in the contents of the alimentary canal of human beings and domestic quadrupeds. If pigs are permitted to eat these, as in Ireland or in many British piggeries, we must expect hams, bacon, and pork sausages to be charged with the embryonic forms of human entozoa. Whereas in Iceland the _dog_ is the victim of human negligence, and _en revanche_ the cause of human disease, in the British isles the _pig_ holds this unenviable position. We have good reason to believe, with Moses, that the pig is an unclean beast; but without discarding him from the scanty list of animals to be eaten, it is evident that we can purify the race of swine, and thus prevent human as well as porcine maladies.” On the authority of Rupprecht, as quoted by Davaine, I append a list of the principal epidemics observed in Germany during the first six years immediately following the discovery of trichinosis: 1. Two slight epidemics in 1860 in the Island of Rügen; 10 to 20 patients (Dr Landois). 2. An epidemic at Stolberg, 1860 (Dr Fricinus). The number of trichinised persons was not stated with certainty. 3. Five epidemics during five summers, 1858 to 1862, at Magdebourg. The number of patients was 300, two only died (Dr Sendler). 4. An epidemic at Plauen in 1862, 20 patients (Böhler). 5. Gusten, 1861, 40 cases, all cured (Fränkel). 6. Epidemic in the Province of Armsted (Mansfeld), 1861, 8 patients. 7. Hettstädt, January and March, 1862, 8 to 10 patients. 8. Blankenburg, 1862, 278 cases, 2 deaths. 9. Calbe (Prussia), 1862, 38 cases (9 men, 25 women, 4 children), 8 deaths (Dr Simon and Dr Herbst). 10. Burg, in Magdebourg, 1863, 50 patients, 10 deaths (Dr Klusemann). 11. Quedlinburg, 1863, 9 patients, 1 death (Dr Behrens). 12. Plauen, 1863, 21 patients (Königsdörffer). 13. Falkenstein, 1863, 4 patients (Drs Bascher and Pinter). 14. Posen, August and September, 1863, 37 patients (Dr Samter). 15. Hamburg, 1863, 2 patients (Dr Tüngel).
