2 17 T H E ANATOMICAL DYESCRIPTION OF EIGHT -OSTRICHES. HeG Eight Ojiriches which we dercribe, were almnof of one fize. There T were five Males, and three Females ; they were feven Foot and a half from the top of the head to the ground; from the Back to the Crown of the Head they were three foot, and as many from the Belly to the ground.
