 lymphatic vessels, and runs along them very earily. In this way one can easily inject the 

 glands of the leg and abdomen, and even the thoracic duct. The lymphatics of the testis arc 

 injected in the same way. It is easy to demonstrate the lymphatics in the intestinal wall and 

 in the liver by the same method. Instead of a syringe, one of the constant-pressure arrange-
