were obtained in group or individual testing of cows on a farm
in the Borough, in Consequence of which three cows were
slaughtered under the Tuberculosis Order, 1925, and found to be
affected. One sample was from a supply coming from Sussex;
a considerable number of cows were examined by the Authority's
Veterinary Officers, suspected animals isolated, and samples
taken. As the result of their investigations one animal was dealt
with under the Tuberculosis Order, 1925. Two samples were
taken from supplies coming from Surrey, and after a considerable

affected with tuberculosis and dealt with under the Order. One
