in 1906 the Minister of Agriculture Mr. 

 Ezequiel Ramos Mexia, placed his breed- 

 ing establishment of Miraflores at the 

 disposal of Professors Bossi and Lig- 

 nieres so that they might try the new 

 method of diagnosis ophtalmo-cuti-ther- 

 mo-reaction. The experimentalists cpe- 

 rated upon pure-bred imported animals, 

 and pure bred pedegree cattle, in spite 

 of this, the proportion of tuberculous 

 animals hardly reached 1 °[ . 



These experiments were extended to 

 two other Breeding Establishments (Caba- 

 flas). In the first 7 imported Durham cows 

 were tuberculined. of which one reacted. 

 Tuberculine was applied also to 24 bulls 

 bred under cover, of 18 to 24 months 

 old, born in this country. None of them, 

 shewed reaction even ^>f 39.5° c, Five 

 Durham bulls, pure-bred, imported, all 

 over 8 year olds; and 5 calves and heifers, 

 pure bred, pedegree, of 6 to 14 months 

 <»ld, were dealt with. One of the bulls 

 shewed reaction, but none of the calves.
