MANIS. 351 



Fallopian pole of the right sack, hut divided into two at its extremity, and the other 

 end of the tract ceased at the point where the chorion was hent on itself to reach 

 the left horn, although the great vessels were also found along that sack. The 

 centre of the hare tract throughout the greater part of its extent was marked hy 

 two parallel longitudinal folds, which joined each other at their lower ends. I did 

 not detect on this tract bodies resembling those which I have figured as occurring 

 in Orcella. Prom the point where this bare tract ceased, a short narrow fringe 

 was continued on to the left horn. The bare patches on this chorionic surface were 

 much the same as in the right horn, but the last third or Fallopian extremity of 

 the horn was destitute of villi ; the surface of the chorion, however, opposed to the 

 orifice of the Fallopian tube was thrown into a number of fine convolutions, which 

 doubtless closed the orifice, but were also free of villi. The bare patches were 

 much more irregularly distributed on this diffuse placenta than in JPlatanista or 

 Orcella, and they were less numerous, but their structure was essentially similar. 



The vilh w^ere distributed in irregular wavy lines, which freely anastomosed 

 with each other, but I did not observe that the ridges of the chorion started from 

 the margins of the bald stripe and ran round the horn as has been described by 

 Sharpey in the membranes of the Manis he examined, but towards its margins there 

 was a distinct but local convergence of the fine ridges of the chorion. They were 

 all closely separated from each other by narrow interspaces destitute of villi. The 

 villous surface viewed under a low power had the appearance of being composed of 

 minute ridges, which gave off still much more minute secondary ridges, which an- 

 astomosed with their fellows surrounding them, so that a highly reticulated appear- 

 ance was produced, the secondary ridges enclosing clear interspaces destitute of 

 villi, but varying little in size, and proportionate to the size of the primary 

 ridges ; these primary ridges did not exceed 0'80" in length, and the interspaces 

 had about the same dimensions. The surface of the mucosa had much the same 

 appearance, the clear interspaces corresponding to the villous tufts of the chorion. 



The amnion invested the w^hole of the inner surface of the chorion except 

 that portion of it on which lay the allantois, which had much the same propor- 

 tional capacity and relative arrangement as in Orca, Orcella, and Tlatanista, 

 reaching from near the Fallopian end of the right horn into the first portion of 

 the left horn, but how far into the latter I cannot say, as its walls had ruptured ' in 

 the left sack. A small umbilical vesicle was present. The cord measured 2 -25" 

 in length, and on its amniotic covering I observed two cyst-like bodies imbedded 

 in its substance and doubtless glandular in their nature, and one oval-shaped 

 pedunculated body with tw^o processes near its extremity, from which a long 

 filament hung dowm. This body probably corresponds to the hippomanes of the 

 cord of the mare. The amnion nearer the allantois was covered with minute 

 rounded bodies hke those I have described on the amnion of Flatanista. 



It was by a mere accident that I became possessed of this uterus, and as the 

 temperature at the time was 95° Fah., I was not in a position to make any 

 injections of the chorionic vessels to ascertain the character of the villi, nor of the
