point was the following observation made by Dr. La CHAPELLA: 
“After reposition of the stump of a tied up hernial sac in non- 
incarcerated hernia femoralis, a more or less sharp border may be 
felt when passing the finger under Poupart’s ligament, the border 
constituting an arch over the os. pubis. The question to be answered 
runs as follows: Has this border, which will incarcerate the hernial 
sac, even before Poupart’s ligament does so, been prefor- 
med anatomically, and if so, what is it? 
We might alter the question and say that we have to establish the 
identity of a clinically tactily ligament, which being concentric 
with Gimbernat’s ligament, but located on a deeper level, 
narrows the entrance to the crural canal. Now, seeing that, as we 
read in surgical manuals, the incarcerating factor proper of the hernia 
femoralis is not known precisely, because after the removal of 
Poupart-Gimbernat often still further cleaving of deeper fibers, 
entwining the neck of the hernial sac, is required, we deemed it 
worth our while to look into this matter from a practical as well 
as from a theoretical point of view. This inquiry was begun by — 
myself in conjunction with Dr. La Caapenia. Only a considerable 
time later could I conelude it, thanks to Prof. vaN DEN Brork’s and 
Prof. Baren’s kindness in granting me the loan of their material at 
Utrecht. I also feel indebted to Dr. van Rissrr, at the time prosector 
for pathological anatomy at Utrecht, for yielding me an opportunity 
to verify the results obtained in the anatomical laboratory at an 
obduction “ corpse. I thus examined three corpses in all, two male 
bodies and one female, while of another female corpse sagittal frozen 
sections through the pelvis were examined. 
When removing from the triangle of Scarpa the skin and the 
superficial layer of the fascia lata, and cautiously cleansing the 
large deep lymphatic vessels, it will be seen that the latter disappear 
into the medial upper angle of the regio, where by the aid of 
Gimbernat’s ligament, the ligament of Poupart touches upon 
the pecten ossis pubis and fastens itself to the fascia pectinea. This 
convergency of the lymphatic vessels, besides the location im situ 
of one or more of the lymphatic glands (Rosemiiller’s glands) 
induce us to suspect Cloqnet’s septum to lie in that corner 
of the inextricable fibrous tissue. This septum Cloqueti is described 
as a subdivision of the fascia transversalis, which after fastening 
itself to Poupart’s ligament extends to the os pubis and thus 
obturates the entrance to the crural canal, as a vertical septum 
pierced only by lymphatic vessels. But, if we closely consider what 
our preparation reveals, there seems to be something wrong, viz.
