218 SPECIFICS FOR THE ALIMENTARY TRACT 



gastric juice, but this has been proven erroneous and their only use 

 is to neutralize hyperacidity, dissolve mucus and stimulate the 

 stomach. The following are the most important : 



Sodium Bicarbonate Magnesium Carbonate 



Liquor Calcis (lime water) Calcium Carbonate 



Magnesium Oxide Ammonia 



Sodium Bicarbonate. This is indicated in disorders of the 

 stomach to neutralize or counteract acids formed by fermentation 

 of food or an excess of hydrochloric acid. It often produces good 

 results in mild forms of indigestion when administered with a bitter 

 and carminative before feeding or at the time of feeding. It is 

 also useful as a gastric sedative in combination with one of the 

 bismuth preparations in gastric catarrh. 



Liquor Calcis. (Lime water) is very serviceable in prolonged 

 vomiting due to excess acidity, also in chronic gastric catarrh with 

 increased secretion of mucus. In this condition it may be used as a 

 stomach wash (lavage) in small animals. It is frequently added to 

 milk for calves and puppies to prevent the formation of large masses 

 of casein in animals fed exclusively on milk. For this purpose it is 

 used in the proportion of one part of lime water to four of milk. It 

 is also serviceable in cases of irritable stomachs of dogs with hyper- 

 acidity, associated with vomiting. 



Calcium Carbonate, (Common chalk). This is a bland ant- 

 acid and feeble astringent. It is often employed in diarrheas for its 

 protective, antacid and astringent effect, as follows: 



Astringent for Cattle.

Magnesium Oxidum. Calcined magnesia. There are two 

 forms of this drug, the heavy and light magnesia. They are used 

 chiefly as antacids and laxatives in young animals or as anti- 

 dotes to arsenic poisoning either alone or in combination with iron 

 in the official arsenic antidote, Ferri Hydratum cum Magnesii Oxido. 



Magnesium Carbonate. Similar to above. May be combined 

 with Magnesium sulphate with good effect as in
