Fig. 3. Part of a section of lung, showing the branching tubules embedded in discrete masses of con

 terstitial connective tissue is also present in large relative amount. 



Fig. 4. Portion of a longitudinal section of the ovary : — 



ep. Surface epithelium (germinal epi- 

 thelium). 

 c. Cortical zone with primitive ova and 



some stroma. 



s. Dense stroma forming a kind of tunica 

 albuginea. 

 m. Medulla with a few masses of ova and 

 much stroma separating them. 



Fig. 5. Part of a section of the pancreas, showing typical arrangement of branching tubular acini, with 

 but little interstitial connective tissue. 



Fig. 6. Portion of a vertical section through the developing cochlea showing one turn of the spiral 

 in section : — 



s.v. Scala vestibuli. 



R. Membrane of Reissner. 

 ex. Canal of the cochlea. 



B. Basilar membrane, with rudimentary organ
