DISBASBS OF THK DIGESTIVE ORGANS. 57 



Gastritis. This is an inflammation of the mucous membrane hning 

 the stomach. Symptoms not well marked and are generally due to me- 

 chanical irritation or irritating or corrosive poisons in large quantities. 

 There is a feverish condition, colicky pains, and intense thirst. When 

 poisons have produced gastritis there will be other symptoms according 

 to the poison swallowed. 



lyead Poisoning'. This occurs near paint works, near newly paint- 

 ed buildings and fences, and where paint kegs are left in the fields, and 

 where water runs through new lead pipes. Lead poisoning produces 

 labored breathing, abdominal pains, partial paralysis, tottering gait, 

 convulsions, and death. 



What to Do. Give thirty to sixty drops of sulphuric acid in a 

 half gallon water. Follow with or precede if not ready at hand, either 

 milk, white of eggs, oil of any kind, flaxseed, gruel or tea. If the poi- 

 son is due to long taking of small quantities of lead or from water flow- 

 ing through new lead pipes, give from one-half to a pound of Epson 

 salts. Iodide of potassium in one dram doses, twice a day are of much 

 service. If much pain is manifest, give three to five grain doses oi 

 morphine, two or three times a day. 



Arsenic Poisoning. When the poison is arsenic there will be 

 symptoms of abdominal pain, nausea, purging accompanied by an offen- 

 sive odor, staggering gait, quickened breathing, paralysis of hind ex- 

 tremities. Poisoning from arsenic is most common where sheep have 

 been dipped in arsenical baths to cure "scab" and then run on pas- 

 ture without first drying their wool. Arsenic is thus deposited on the 

 grass and is eaten by animals in the pasture. Give oil, milk, white of 

 eggs, and flaxseed gruel or tea. Powdered opium in one-half dram 

 doses two or three times a day may be given to allay the pain and in- 

 flammation. Care should be observed in feeding for a time, giving only 

 soft and easily digested foods. 



Note. — Gastritis may also occur from poisoning by copper, corrosive 

 sublimate, and some vegetable poisons. 



Stones in the Stomach. Gastric concretions, calculi (stones) in 

 the stomach have been most found in millers' horses. A small piece of 

 mill stone or other substance forms a centre around which is gathered 

 in layers the stony substances which abound in their feed, (sweepings 

 from the mill floor). There are few symptoms exhibited that will lead 

 us to suspect calculi and probably none by which we can unmistakably 

 assert its presence. There is a depraved capricious appetite; a disposi-
