 thirds long, by four-fifths of an inch in width.

 a day, and continue to give milk until they are impregnated anew. 



The escutcheon is yet more reduced in size, and is now hid away between the 

 thighs. To the right and left of the vulva, are two patches of ascending hair,

 long by two and a half wide.
