Fig. 65. Photograph of a hen'? oviduct which has been removed, 

 slit longitudinally throughout its length and opened out flat in order to 

 show the gross anatomy. In order to get the whole duct on the photo- 

 graphic plate it was necessary to transect it at about the middle. A, 

 the infundibulum. Note muscle fibers in wall and absence of any ex- 

 tensive gland development. B. albumen secreting portion; note heavy 

 glandular development. The albumen portion ends and the isthmus 

 begins at x. The line of demarcation is very distinct in the freshly 

 prepared oviduct. C, the the isthmus. D, the uterus or shell gland. 

 E, the vagina. About one-third natural size.
