In sheep, cats and rabbits undiluted thyroid lymph has been collected at some distance from the thyroid from individual lymphatic vessels which drain the gland. It has also been collected from lymphatics on the surface of the gland. In animals which had been injected previously with 131 I, the thyroid lymph has been found to contain a concentration of radioactivity considerably higher than that in either thyroid venous plasma or systemic blood plasma. This has been found to be the case in all three species of animal and both before and after giving thyroid stimulating hormone (TSH). Almost all the radioactivity in the lymph was due to organic 131 I. An appreciable part of the iodine compounds leaving the thyroid gland is carried away in the lymphatics.
