intraovarian pressure in such ovaries leads to a relative pre- 

 ponderance of what corresponds to the interstitial gland in the 

 ovaries of certain other species. The concrescence of ovarian 

 follicles is analogous to the union of neighboring acini in the 

 mammary gland and thyroid. It is a phenomenon which occurs 

 probably in all or the majority of glandular structures.
