Fig. 2 A series of records showing the reaction of a lymphatic capillary 

 toward an injected globule of olive oil. The first sketch, May 5, was made im- 

 mediately after the injection. The next drawing, sixteen hours later, shows the 

 globule surrounded by pigmented leucocytes and the lymphatic apparently 

 growing toward the globule. The next two sketches show the lymphatic sprout 

 approaching the globule and in the last one, the lymphatic has reached the oil. 

 and the tip is in close proximity to the globule and to the rim of leucocytes. 

 Note that the blood vessel shows no reaction toward the globule but instead it 

 retracts during the observation. B.V., blood vessel; lym., lymphatic; p. L, pig- 

 mented leucocyte; c.l., clear leucocyte. Enlargement = 140x. Drawn with 

 camera lucida.
