In the uterus three months pregnant I find essentially the some 
conditions except that the degeneration is farther advanced since the 
traces of cellular structure in the reflexa are still more vague and 
the fibrine is more developed. The membrane is much thinner than 
at two months; the thickness is about two thirds of what it was. In 
the fresh specimen the membrane appeared much more transparent 
than before. In all the parts examined I found leucocytes present

far from the base of the reflexa the three layers are distinct as at
