The relations of tuberculosis of the lymph glands to tuberculous processes in other organs have received much attention, but there still are differences of opinion, and careful observations are therefore of much interest. Harbitz1 has just published the results of an extensive and painstaking study of tuberculosis of the lymph nodes. He says:
