Summary A technique is described for formulating the left cervical lymph trunk of the duck which permits the collection of lymph for periods of from 5–10 days. In the seven experimental birds studied the mean lymph flow from the left cervical lymphatic was 1·0 ml per hour and the mean total cell output was 4·1 × 10 6 cells per hour. The predominant cell type in the lymph was the mature lymphocyte which comprised, on average, over 96% of the total cell population. However, all the cell types found in the blood of the normal animal may be found at some time in the lymph. Lymphocytes collected from the cervical lymph and labelled with 51 Cr in vitro , when injected back into the blood, subsequently appeared in the cervical lymph. Even though lymphoid nodules were present in the area drained by the cervical lymph duct, it was considered that few lymphocytes were being newly formed in these areas; the lymphocytes present in cervical lymph were thought to be migrant cells originating from the blood.
