Prof. Russell : I have had two experiences, lesions I could 

 not find, where these tubercular lesions have been found in un- 

 usual parts of the body. I had a case a few years ago in one of 

 these public post mortems ; there was not the slightest trace. I

 carefully by competent persons and an exhaustive examination 

 has been made and in 98 to 99 per cent of the cases the evidence

 who have no financial interest in the herd. They are then turned 

 over to the State Veterinary and are sent to the Federal Packing 

 House at Milwaukee, LaCrosse, or the nearest point where
