 about 0'127 mm. in diameter. 



Fig. 3. The liver of the same fish. Commencing 

 mycelial growth of the fungus. 



Fig. 4. Part of a section of the liver of the same fish. 

 Spore-like bodies, the largest of which is 

 about 0065 mm. in diameter. 



Fig. 5. Ovarian cysts in Lophius. Section of part of 

 the thin wall of a cyst. Fine fibrous tissue 

 with discharged goblet cells. The thickness 

 of the wall is about 006 mm. 



Fig. 6. Ovarian cysts in Lophius. Section of a thick- 

 walled cyst. Mucous epithelium with 

 closely-crowded goblet cells. Goblet cells 

 about 004 mm. in height, 



Fig. T. Ovarian cysts in Lophius. Part of the section 

 represented in fig. 6 seen under greater 

 magnification. Fine columnar epithelium 

 with large goblet cells. 



Fig. 8. Ovarian cysts in Lophius. Section through 

 one of the villus-like projections on the 

 internal wall of a cyst. Goblet cells cut 

 mostly at right angles to their greatest 

 diameter. Diameter of the " villus " 

 about O'l mm. 



Fig. 9. Fibromatous tumour in Halibut. Tubular 

 structure from the tumour. Thick fibrous 

 capsule surrounding the tubule, the wall of 

 which is composed of columnar epithelium. 

 Outside the tubule small rounded cells. 

 Diameter of the tubule about 0135 mm.
