The other affects the glands, bones, abdomen and meninges or covering of the brain and is known as the non-respiratory or non-pulmonary form. Of this form some 60% is caused by the human strain of the mycobacterium and some 40% by the bovine strain ; the relative amounts, however, vary in different parts of the country depending on the amount of tuberculous milk consumed. To prevent non-respiratory tuberculosis caused by the bovine type of the mycobacterium it is neces¬ sary either to produce our milk from cows free from tuberculosis or to subject all milk to efficient treatment by heat. (To avoid discrepancies due to small numbers I have grouped the three districts together and refer to them below as the area.) I give in Table 9 the deaths from respiratory tuberculosis since 1882 and of non- respiratory tuberculosis since 1906 in the three districts. Because the boundaries of the districts of Guisborough, Skelton, Brotton and Loftus have not remained exactly co¬ extensive throughout these sixty-seven years, I have also given the figures of the populations at risk throughout the period. I hope that this procedure will make the data to a reasonable degree comparable. For these statistics I am indebted to the careful and full annual reports of my two predecessors in office, Dr. W. W. Stainthorpe from 1882 to 1918 and Dr. C. R. Gibson from 1919 to 1946. Only during the war years of 1916-1918 and 1939-43 were there no records written of the relevant figures. There are points in Table 9 * For completeness I mention a third strain affecting birds, but this is of no importance to the public health. 8
