  The coefficient of correlation was .3166 x .0317. The T

  accurate indicator of the future value of that sheep as a wool

    · out Kentucky, and especially in the Bluegrass region, have
  Z Z experienced severe losses in pregnant ewes during the last three C1,
  `V years. The same disease has been previously observed in dif- pl
  _ ferent parts of the United States and it has also been reported I fc
V   I ` in various European countries, where it is known as acute dif- Si,
    ' * _ fuse parenchymatous hepatitis. The disease occurs a few p,
  i· i weeks previous to lambing time and may continue thruout the P,
  -.._.. lambing period. In docks, so affected, it has caused a 10 to 25 pl
  ' ._ per cent loss of ewes. As yet, the causative factor is not ti,
  ' iknown. It is apparently a non-infectious or non-contagious bi
  _ disease, as repeated attempts made at this station to t·1`21]1S11lli . C5
