undergoes regression, until all the new vessels concerned in its nutrition have disap- 

 peared and the circulation of that particular part of the ovary is permanently reduced. 



The function usually ascribed to the corpus luteum is that of filling the empty follicles and 

 thus restoring the equilibrium of circulation and tension. Clark 1 regards the corpus luteum as 

 rver of the circulation, since, when performing its functions most perfectly (during the 

 earlier years of menstrual life), it effects the elimination of the effete follicle and the superfluous 

 blofxl-M-sscls without leaving dense and disturbing scars. It is probable, however, that the cor- 

 pus lutriim plavs a more important role and that it functions as an organ of internal secretion, 

 producing substances influencing the formation of the uterine deciduae and the proper fixation 

 of the fertilized ovum. Moreover, it may be related to lactation. 



The origin of the lutein cells has long been a subject of discussion, and even at present 

 two opposed views share the support of eminent anatomists. According to the older theory, 

 advanced by Baer, these cells are modified connective-tissue elements, derived from the pro-
