La degeneration peut être chromatolytique et graisseuse, ehromatoly tique et 

 hyaline, chromatolytique et fragmentation (irrégulière parttiénogénétique) ou 

 graisseuse et fragmentation etc. Chez les Mammifères les cellules de la granu- 

 leuse et les leucocytes ne pénètrent dans l'ovule qu'aux derniers stades de la ré- 

 gression. (Rat, Souris, Rhinolophe, Chatte, Poule, Moineau, Lézard, Orvet.)

Por his researches on the structure of the placenta H. had 469 uteri of Tupaia, 

 137 0Î Nyclicebus , 72 of Galeopithecus , 198 of Tarsius and 150 oî Manis to dis- 

 pose of. Only Tujjaia produces never more or less than two young ones at a time. 

 Only one case of twins in Nycticehus occurred. All the other species bring forth 

 only one young at a time, but pregnancy is repeated at rapid intervals. With re- 

 gard to the origin and morphological significance of the cell layers constituting 

 the two-layered blastocyst of Mammals H. proves (against Robinson), that 

 the outer layer of the Mammalian monodermic blastocyst (i. e. the trophoblast) 

 is not in direct continuity with the hypoblast cells inside of it. The monodermic 

 mammalian blastocyst is a pseudo-blastula stage , its cavity is not the real seg- 

 mentation cavity; the embryo is inside this cavity. The segmentation is not a 

 real holoblastic one. The precociously segregated cells of the epiblast form the 

 trophoblast, the proliferating activity of which stands in direct relation to the 

 development of the placentary fixation of the blastocyst. Concerning the origin 

 of the placenta and its minute anatomy, there is no common type in the Insecti- 

 vora, but a difi'erent one for nearly every genus.
