Farre^ on an Early Human Embryo. 
Wolffian body^ one of the earliest and most transient of 
embryonic structures. 
As yet there is not only no indication of distinct sex_, but 
the period of development is apparently anterior to that stage 
of embryonic life in which those organs are distinguishable,, 
which^ according to the views of Kobelt^ may be subsequently 
converted into the essential parts of either sex indiscrimi- 
nately. But upon this point I would not be understood as 
expressing a decided opinion, because the rudimental struc- 
tures here distinguishable will require a more critical ex- 
amination than I have been yet able to give to them. 
[At the conclusion of this paper the author gave a brief 
exposition of his views regarding the signification and homo- 
logies of the principal structures here described.]
