of '2 J to 4 drachms, sulphate of magnesia, etc. By evacuating the bowel 

 and removing a large number of the germs \Yhich have multiplied there, 

 they arrest intoxication and prevent infection. Nevertheless, they should 

 not he administered for long, and after one or two doses should be fol- 

 lowed by antiseptics like benzo-naphthol, in doses of 15 to 30 grains, sali- 

 cylic acid in doses of 5 to 10 grains, or salicylate of soda 45 to 60 grains. 

 Mucilaginous and sweetened drinks containing lactic acid in doses of 45 

 to 75 grains per day may be given between the meals, or at intervals if 

 the calf is sucking. 



Laudanum in doses of 6 to 10 drops per day administered in rice 

 water, extract of opium, weak solutions of tannin, etc., are also of value. 

 Filliatre has successfully used tar water in the first stages. The solution 

 consists of vegetable tar 6 drachms, boiling water 1 quart. This solution 

 is used tepid in the proportion of 1 part to 3 parts of warm milk. 



Decoctions of spiked purple loosestrife, willow bark, etc., are also of 

 great value in certain districts. 



The drug wliich appears least dangerous, however, is that so often 

 successfully used in young children — viz., subnitrate of bismuth. It 

 can be given in doses of 30 to 45 grains per day, with lactic acid in doses 

 of 75 to 150 grains, according to the size of the patients. If the animals 

 are greatly exhausted and have been ill for some time there is less chance 

 of recovery, and under these circumstances Dr. Lesage's anti-colic serum 

 might be used. 



It gives excellent results in infants, and it has proved successful in 

 simple diarrhoea of calves.
