 (j) Pancreas. 



The pancreas of a dog was hardened in mercuric chloride, 

 stained in Dehifield's hsematoxylin, embedded in paraffin, and sec- 

 tioned. Fix sections to the slide, and mount in balsam. 



Study first under low power. The structure of the 

 pancreas is in many ways similar to that of a, serous sali- 

 vary gland. Note the inner granular zone in the cells 

 lining the alveoli; the nucleus is found in the outer zone.' 

 Sketch several alveoli as seen under high power.
