1908.] Suppression of Tuberculosis. 495 



Agriculture, and that isolation was satisfactorily carried out. 

 By a law dated 26th March, 1898,* the grant was doubled and 

 made applicable to cattle of all kinds, instead of to young 

 cattle only. Imported cattle not intended for slaughter were 

 required to be tested, and those reacting were to be either 

 refused admittance or killed. Native cattle found to be 

 attacked by tuberculosis of the udder were required to be 

 slaughtered, a portion of the value being paid as compensation. 

 Milk or butter-milk supplied by dairies as food for animals 

 was required to be heated to a temperature of 185 9 F. (after- 

 wards reduced to 176 0 F.) . This latter provision was intended to 

 prevent the infection of calves by the mixed separated milk 

 returned by the butter factories. 



The method adopted, which is based on the recommenda- 

 tions of Dr. Bang, aims at the extirpation of bovine tuber- 

 culosis by the voluntary action of cattle owners, who are 

 assisted in their efforts by the gratuitous inoculation of tuber- 

 culin by the State veterinary officers, the owners on their part 

 providing for the isolation of the reacting animals and their 

 slaughter when fat, and for disinfection of buildings, &c.- 



The system is for the whole herd on a farm to be first inocu- 

 lated and the animals which react separated from those which 

 do not. No fresh cattle are added to the group of healthy 

 animals unless they have been tested and found free from 

 disease, and the whole of this non-tuberculous herd is tested 

 annually or at intervals to ensure that tuberculosis has not 

 appeared among them. The reacting group is treated as a 

 separate herd, and either fattened for the butcher at once or 

 reserved for future disposal at the will of the owner. 



Calves born of reacting cattle are removed immediately 

 after birth to the healthy herd, and, in order to avoid inocu- 

 lating them by means of infected milk, all milk given to them 

 is first sterilised by heating. 



Dr. Bang, in a paper read before the Eighth International 

 Veterinary Congress at Buda Pest in 1905, stated that, up to 

 1904, 17,268 herds containing 404,651 animals had been 

 inoculated, of which 97,070, or 24 per cent., reacted. The 

 number of reactions, however, exhibited some reduction in the 

 later years, the proportion in 1903 and 1904 being 14 -8 and
