not lieen proved by investigation in our 

 own country. Bang has found in France 

 2 7 0[0 of tuberculous subjects between 

 the age of six months to a year; 37 0[0 

 bewteen \} 2 to Z\ years; 43.07 op between 

 2} to 5 years, and 47.05 ojo over 5 years 

 oi age. Martell obtained a very similar 

 mean average (47 o[0 in 8 year olds). 



The application of this rule to our 

 cattle gives us surprising results, bearing 

 in mind that he v e the proportion of cattle 

 over 5 years old, represents a small 

 part of our herds, to such extent that 

 some rural corporations have claimed 

 that Federal Congress should vote laws 

 to prohibit the slaughter of heifers which 

 have not calved. 



Further on we shall find figures dem< >ns- 

 trating the real proportion of tuberculosis 

 in the Argentine.
