While perhaps it is impossible to be absolutely sure of the truth of any general statement, of which from its nature complete proof is unobtainable, we are justified, I think, in assuming that the statement that wild cattle are entirely free from tuberculosis is true.

The appearance of the disease dates from the time when pure-blooded cattle were introduced into that country for breeding purposes. So it has been asserted that the native cattle of the Jura mountains and other places are, and always have been free from tuberculosis.
