against surrounding objects. In corral cases the sheep pushes — 
against the fence, lowering its head so that sometimes the animal | 
almost stands on its head. These attitudes are shown in Plate Iil@ 
figures 1 and 2. If moved from one point it may immediately push _

intoxication, but later are not very different from normal, except 
that the pulse rate is frequently increased just before death. 
The intoxication produces no effect on the temperature, but in long-
