The small fetus, the 'runt' to be, is ap- parently small as a result of nutritive disturbances owing to the ravages of infection, and when born is wanting in vigor. Embryonic death may occur in any order, but as a rule the liability of the embryo to succumb to intra-uterine in- fection conforms to the general principles laid down for the cow.
