in the event of an accident taking place. The operation 

 should only be attempted by skilled persons, who will know 

 the best way to prevent an accident, and guard against its 

 consequences should it occur. 



Since the operation is not altogether unattended by the 

 possibility of loss, and since it incurs a certain amount of 

 expense, one has to consider under what circumstances it 

 will be worth while undertaking it. It will be obvious that 

 on farms registering only one death annually it will hardly 

 be called for, and that it would be folly to adopt it on clean 

 farms. 



It results from observations on several millions of cattle 

 in various parts of the world that accidents occur in about 

 '5 per cent, of the inoculated cattle taken all round, and that 

 the operation may be expected to reduce the death rate from 

 anthrax on infected farms to about 1 per cent, or slightly 

 under. If a stockowner finds that his annual losses from 

 anthrax amount to 2 per cent, he will possibly find it profit- 

 able to have recourse to preventive inoculation. 



It should be understood, however, that since the number 

 of animals dying of anthrax in one year will vary, and since 

 the inoculation must be repeated annually, the estimation 

 of annual losses must be based on two or three years' 

 casualties. 



A certain degree of temporary immunity can also be 

 almost immediately conferred by injecting a dose of anthrax 

 serum, and the injection produces no accidents. Where 

 animals have been exposed to the risks of what might be 

 called gross infection (for example, when a carcase has been 

 carelessly dealt with on a pasture) it is advisable to inject 

 them immediately with serum, and remove them to another 

 field. 



At the meeting of the International Dairy Congress, which 

 took place at Buda-Pesth in June last, several interesting 

 papers were read dealing with the 

 Effect of Food on influence of food on milk production. 

 Milk Production. Professor Kellner, of the Mockern 

 Agricultural Experiment Station, put 

 forward some interesting reasons for the fact that the feed-
