most infectious diseases has been noticed and recorded. At the present time the Board of Agriculture have suspended the slaughter order in cases where the owner of the pigs desires to inoculate the in-contact pigs with serum which is supplied from the Veterinary College. The experiment has not been in operation sufficiently long enough to express a confident opinion upon its results, but it is stated that in Denmark the inoculation of the pigs which have been in contact with diseased pigs has proved to be a success. The risks of carrying out the experiment are by no means slight, but appear to be worth running if there be any great probability of success. SWINE ERYSIPELAS The symptoms of this disease, which fortunately is not so common as swine fever, owing probably to its being more fatal and in a shorter time, are very similar to those of swine fever, save that the husky cough and the weakness of the muscles of the back are generally absent. The post mortem shows distinctive differences from those of swine fever. There appears to be far greater difficulty in thoroughly disinfecting the sty in which pigs suffering from erysipelas have been housed than after swine fever cases; not only so, but the virus remains active for a very long period, so that any accident which may expose the virus even after many months may affect any pigs with which it comes in contact. In an outbreak of swine erysipelas it is advisable to have the unaffected pigs inoculated as well as those housed in a sty or building in which at any time pigs suffering from erysipelas have been housed. A certain limited number may die, and a few suffer for a time, but the total loss will be considerably reduced. ANTHRAX, FOOT AND MOUTH DISEASE AND RABIES It may be unnecessary to describe these very infectious or contagious diseases to which pigs are subject, as fortunately the steps taken to stamp them out, and which were much decried when taken by the Board of Agriculture, have proved so successful that the two latter are stamped out, and the first named is so promptly and effectually dealt with that a case of it amongst swine is seldom recorded. CRAMP, DIARRHŒA AND EPILEPTIC FITS These diseases, which are more frequent amongst young pigs, have been fully described in the chapters dealing with the rearing, weaning, and growing of pigs, where it is pointed out that they are all mainly due to faults in feeding, and the simple remedies applicable are there given. Hernia and Scrotal Hernia are also treated upon in the chapter on the Farrowing Sow. INVERSION OF THE VAGINA OR THE UTERUS These two troubles, of which the latter is a complete expulsion and the former only a partial protrusion of the "breeding bag," are generally the result of a difficult or a protracted farrowing. The second is almost impossible of treatment, and indeed may be declared as fatal, so that the loss may be reduced by prompt slaughter.
