attained by the administration of opium in doses of 5-10 gm. for 

 horses and cattle, 1-3 gm. for small herbivora and 0.1-0.3 for 

 dogs. Morphine hydrochloride may also be given in doses of 

 0.3-0.4 gm. or 0!02-0.1 gm. subcutaneously once or twice daily. 

 Provided the primary disease permits of the administration of 

 food this should be easily digested and if possible in fluid form 

 (gruel, soup, milk). The inflammation should be combatted 

 with cold compresses. These may be made by binding linen 

 bandages around the abdomen and soaking them in cold water, 

 or in small animals an ice bag may be placed on the abdomen. 

 After the disappearance of pain and the acute symptoms, fomen- 

 tations or rubbing with turpentine should be resorted to (Priess- 

 nitz). Gray mercurial ointment may be rubbed into the inner 

 surface of the thigh and the abdominal wall repeatedly so long 

 as there is no salivation. For horses 5 gm. and for dogs 1 gm. 

 may be used daily. Mild purgatives, such as castor oil (horses 

 250-500 gm. and dogs 15-30 gm.) and calomel (dogs 0.03-0.05 

 gm.) are indicated for the constipation during the early stages. 

 Lukewarm clysters are advantageous. Cattle should be given, 

 at intervals of two to three hours, water, barley water, oatmeal 

 or linseed tea to prevent the drying up of the food. In cases of 

 enteritis- of some standing disinfectants may be tried (creolin, 

 lysol, resorcin, naphthol, etc.; see page 332). 



Tapping is indicated for the removal of the fluid and this 

 may be repeated as often as necessary. In some cases puncture 

 of the stomach or intestine may be necessary. In chronic peri- 

 tonitis attempts may be made to promote the absorption of the 

 exudate by Priessnitz' poultices and massage, potassium iodide 

 (5-10 gm. for large animals or 0.3-0.5 gm. for small animals 

 daily) and diuretics. Any derangements in other organs must 

 be treated.

3. Tumors of the Peritoneum. 



Occurrence. In addition to tuberculosis and actinomycosis 

 true neoplasms may occur in the peritoneum primarily and 

 metastatically. Diffuse carcinoma and more rarely sarcoma 

 (melanotic) of the peritoneum are seen sometimes. The mem- 

 brane is beset with neoplasms of various sizes and the connec- 

 tive tissue layer appears to be thickened, while the neighboring 

 viscera may be more or less compressed or atrophied. Fibro- 

 mata, lipomata and myxomata, and very exceptionally angio-
