    contain a putrid yellowish fluid mixed with mucus. The mucous membrane is covered with mucus and shows haemorr¬ hages. 'Phe lymph follicles and Peyers patches are swollen. ri'he mesenteric glands are enlarged and oedematous. The mucous membranes of the large intestines show similar changes but not so marked. in type No. 3 one or both lungs show the worst changes. 1 neumonia in diif e rent stages may exist; sometimes there are many purulent centres in the consolidated lung; or darkened and hardened portions of one or both lungs may only exist. In this type too there may be found signs of an old intestinal inflammation, while in type No. 4 an emaciated carcass with anaania and slight changes in the bowels are often the only lessions observed. Diagnosis. As stated above, various organisms may be responsible for calf scours and to accurately determine which is responsible, a bacteriological examination of organs, intestines and the blood is necessary. Treatment. t sually a mildly acting purgative to rid the bowels of the fermenting contents is given, e.g. castor oil. When purga¬ tion commences gruels should be administered. They may be given with or without opium, to which some chalk or magnesia may he added. Intestinal disinfectants such as salicylic acid may be given together with tannin; tanniform, naphthalene, salol has been used beneficially. Animal charcoal has been highly recommended. Injections of saline into the rectum (two litres) repeated if necessary in two to four hours have often given good results. Prevention. Prevention is recommended on the two following lines both of which should be practised together if the disease has already broken out on the farm. (1) Calving the cows down on clean bomas where the disease is known not to have previously existed and immediately the calf is born to disinfect the navel with a solution of one of the proprietary disinfectants. Subsequently to tie the navel cord with a cotton string or a piece of tape about two inches from the abdomen and then to paint the whole of the umbilical region with iodine solution.
