 clouded. Vacuoles small and scattered. 



FIG. 13. 1/4 hour after being allowed to srnell food. 



FIG. 14. 3/4 hour after smelling food. The nuclei contain less chromatin than 

 in the previous spécimen. 



FIG. 15. 1 hour after smelling food. The nuclei are becoming clouded. The 

 spherular protoplasmic precipitate is easily seen. 



FIG. 16. 1 1/4 hours after smelling food. The nuclei are still clouded and 

 some dark masses of zymogen are visible in the cytoplasm. 



FIG. 17. 1 1/2 hours after smelling food. The nuclei hâve again almost come
