428 ELIOT R. CLARK AND ELEANOR LINTON CLARK 



May 6 



Fig. 3 Another series of records, showing the reaction of a lymphatic capil- 

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

 immediately after the injection. The successive sketches show that the lym- 

 phatic, although pointing to the right at the time of injection, soon sent out a 

 sprout to the left, which grew toward the olive oil. The sketches also show the 

 retraction of a blood-vessel which was near the globule at the time of injection. 

 B.V., blood vessel; lym., lymphatic; c.l., clear leucocyte; p.l., pigmented leuco- 

 cyte. Enlargement = 140x. Drawn with camera lucida.
