Fig. 17 Lymphatic sprout from the hyla pickeringii larva on which studies 

 in figs. 1 to 14 were made, showing mitotic division of a nucleus. This division 

 took place on May 5, while the larva was anesthetized with chloretone. The num- 

 bers show the time. From 9:18 to 9:44 inclusive, the dividing nuclear area alone 

 is shown. Enlarged approximately 450 times.
