  {Red  blood  corpuscles}  (Physiol.),  in  man,  yellowish, 
  biconcave,  circular  discs  varying  from  1/3500  to  1/3200  of 
  an  inch  in  diameter  and  about  1/12400  of  an  inch  thick. 
  They  are  composed  of  a  colorless  stroma  filled  in  with 
  semifluid  h[ae]moglobin  and  other  matters.  In  most  mammals 
  the  red  corpuscles  are  circular,  but  in  the  camels,  birds, 
  reptiles,  and  the  lower  vertebrates  generally,  they  are 
  oval,  and  sometimes  more  or  less  spherical  in  form  In

  are  all  white  or  colorless.

  the  average  size  is  about  1/2500  of  an  inch,  and  they  are 
  present  in  blood  in  much  smaller  numbers  than  the  red 
  corpuscles.
