    The observations of De Graaf, Haller, and others, have proved that a corpus luteum is invariably formed after impregnation in the situation of the Graafian vesicle, from which the ovum had es¬ caped ; but whether the corpus luteum is pro¬ duced by a thickening of the inner layer of the vesicle, or is an entirely new substance deposited between its coats, or around its external surface, and whether corpora lutea are not formed in the ovaria of some women who have never been preg¬ nant, physiologists have hitherto been unable to determine. Professor Baer is of opinion that the corpus luteum is formed in all animals by a thickening of the inner membrane of the Graafian vesicle. “De corporis lutei genesi satis dissentiunt observatores. Me judice minime corpus novum est, sed stratum internum thecae magis evolutum. Quod sequen- tibus observationibus demonstrari posse puto.* Dr. Montgomery believes that the corpus luteum is formed between the coats of the Graafian ve¬ sicle, and does not consist, as Baer has supposed, of a thickening and puckering of the inner layer of the vesicle. “It will appear,” he*observes, “very obviously from the above description, that I believe the corpus luteum to be surrounded externally by the outer membrane of the Graafian vesicle, while its cavity is lined by the inner membrane of this vesicle; the corpus luteum being, in fact, enclosed * C.
