]HiX is at first careless of the teat, and as the ulceration progresses it l)c- 

 cornes unable to suckle. The ulcers form quite readily on the lips, snout 

 .ind tongue, appearing as light colored spots elevated above the hoaltli.v 

 tissue. These soon break down and slough otf, leaving deep, cavernous 

 excavations that may involve several of the teeth or a large portion of 

 the lips or snout. The ulcers on the face and body appear as brown 

 scabs that soon open into deep pits or cracks. The pig acts very dull, is 

 feverish, and being unable to suckle, becomes greatly emaciated and soon 

 starves to death. In advanced cases treatment does but little good. If 

 recovery does occur, the pig is usually stunted, or deformed about the 

 face or lips. The disease may end fatally in from three to ten days. 



Treatment.— The preventive treatment is very important. The dis- 

 eased pigs should be isolated from the healthy ones, the pens kept clean 

 and disinfectants used freely. The diseased pigs should be dipped head 

 foremost into a two per cent, water solution of any of the coal tar 

 l)roducts or the mouth, dipped into a solution of permanganate of potjis- 

 sium (one ounce to the gallon of water). This must be repeated once a 

 day for several days. It is also best to wash the udder of the mother 

 with a similar solution. When the ulceration is well advanced, the dead 

 tissue should be removed and lunar caustic I'ubbed on the parts. It is 

 usually best to destroy such animals. 



Diseased Teeth.— The hog eats all sorts of objects, and cracks nuts, 

 coal, gravel, etc., upon the teeth, so that w^hen the hog becomes old he is 

 almost sure to have a bad mouth. Hogs sold for stock purposes are 

 seldom affected in this way. Boars sometimes have very long tusks. 



Symptoms. — The symptoms of some derangement of the teeth are 

 pain upon grinding, holding the head to one side while eating, insufTicieut 

 mastication, as seen in the half or whole grain passed, and inability to 

 shell corn from the ear. 



Treatment.— The treatment is to give largely ground or sloppy food, 

 and pasture. Cut off with dentist's cutters all long tusks, but do not 

 knock them out with a punch or cold chisel, as the latter method is almost 

 sure to crack the teeth and fracture the jaw. 



.Black Teeth.— This condition is frequently brought to the attention of 

 tlie veterinarian, but as yet we have no satisfactory explanation to offer 

 for their presence. They are also foiind in health, as we have ol)served 

 in the heads at the slaughter house. Undoubtedly too much stress has 

 been laid upon this condition. We are not inclined to attribute any dis- 

 ease to this condition ujion the present evidence. In very yoiuig pigs, 

 where this condition is most frequently seen, there may be very long, 

 sharp teeth present which it would be better to cut off. At the time of 

 dentition the temporary tooth may be present, as a dark shell, and the 

 gums be made sore, and cause the pig to hold the mouth open to tsali- 

 vate, and to refuse food. 

 Depraved Appetite. Causes.— Depraved appetite is due to a variety of
