find that immediately against the umbilicus there is a dense area 

 extending for a distance of about i >^ inches, which ends some- 

 what abruptly by a marked ring in the soft umbilic cord. This 

 projection, A, Fig. 90 B, consists of a hairless skin, which, in the 

 healing of the navel, atrophies and disappears. In the calf, the 

 corresponding cutaneous navel is haired and persists for some 

 months as a conical projection of skin, thickly covered with long 

 hairs. Just beyond this point, one or two inches from it in the 

 foal, is the weakest point in the cord, and it is at this point that 

 it ruptures or is torn in two.

After it ruptures, the behavior of the parts when left undis- 

 turbed is interesting and highly suggestive of the degree and 

 character of interference demanded upon the part of the attend- 

 ant. One of the most prominent effects of the rupture of the 

 cord by linear tension or by laceration by the teeth of the mother, 

 is the promptness with which hemostasis is brought about, so 

 that as a rule there is but little hemorrhage, appearing usually 

 to not exceed the amount of blood lying in the umbilic veins 

 outside the umbilic ring.
