The following are a few of the principal exceptions to the rule: 

 the doses of the salts of mercury, lead, and copper are consider- 

 ably smaller relatively for cattle than for horses; calomel and other 

 cathartics are given to swine in 10 to 40 times the dose for dogs; 

 cats are very susceptible to carbolic acid; fowls are relatively 

 non-susceptible to strychnin; finally, all the domestic animals are 

 especially tolerant to morphin, atropin, and aconitin, as com- 

 pared with human beings. 



Age must also be considered in determining the dose. Here 

 the general rule holds good : give full-grown animals the full dose, 

 half-grown animals %, younger animals %, very young ones

 other animals may be easily computed from the above table.

 is a valuable antipyretic and heart depressant, but is poisonous, 

 so should be given only under the direction of a veterinarian. 

 It is used in the first stages of fever and for inflammatory condi-

Alcohol is a diffusible stimulant and diuretic. Externally it is 

 used as an antiseptic. Internally it stimulates the heart and 

 other organs so is used in the convalescent stage following severe 

 febrile diseases, and in collapse. The dose is 2 to 4 ounces 

 diluted with water. 



Aromatic spirits of ammonia is a prepared liquid containing
