An infestation with intestinal worms, as shown here, leads to unthriftiness and a loss of flesh. These worms may be expelled by giving turpentine in doses of one teaspoonful in milk for three days in succession.] While making this opening, observe the watery fluid as it escapes. If a large quantity is present, dropsy or a rupture of the bladder is indicated. If the trouble is due to the latter, an odor in the urine will be quickly noted. When the fluid is red in color, it indicates the presence of blood or some inflammation of the abdomen or the bowels. A large amount of watery fluid in the chest cavity is an indication of some lung trouble; this is further indicated by the tiny attachments running between the lungs and the chest wall. =Stomach and Intestines.=--If the stomach and intestines be abnormally red, congestion is indicated, and if they be quite dark, even purple in color, you may be sure that some kind of inflammation has been the trouble. You will note also if the stomach is hard and compacted; and, if so, indigestion may have been the trouble. The intestines will also show if they be hard and compacted or in any otherwise bad condition. Pass the hands along to see if the intestines are knotted in any place or if nails are present in the stomach. It is not likely that the nails have been the direct cause of death, but this fact helps to indicate the condition of the digestion trap. Often hair balls or parasites will be found; either may clog up the channel and may be the immediate cause of death. I have on more than one occasion found that the fuzz of crimson clover, accumulating in the intestines of horses, rolls up into a hard, compacted ball, and not being able to pass out, becomes an obstruction in the passageway and ultimately causes death. =Kidneys and Bladder.=--The urine tells its tale also; a very disagreeable odor indicates some disturbance; and a brownish or dark-red color may indicate a local disease or a constitutional breakdown. Texas fever in cattle produces a very dark or reddish urine, Azoturia in horses, a similar color. Gallstones or gravel are often found in the bladder, and these frequently cause serious disturbance, if not death. =Lungs.=--Look the lungs over carefully. See if the natural color is present and if the soft, spongy constituency responds to the same kind of touch as does the thoroughly healthy lung. In health the lungs are a very light pink color. If inflammation has been present this will be indicated by the dark color and the hard density. When the lung is cut apart with the knife further observation should be made. A marble appearance indicates inflammation and hard lumps or tubercles indicate tuberculosis. These tubercles, when cut open, show pus and a cheeselike material, yellow in color--a true indication of the disease.
