 death. Such outbreaks occur after extraordinarily wet sea- 



sons, when meadows have been flooded, and flocks are being 

 decimated by '^ rot.^' Usually they may be seen about at 

 Christmas time or in the early spring. The collateral 

 conditions of the case, together with a yellowness of the

 cases from those of simple anaemia. 



Our efforts must be directed to support of the strength

 is especially called for. Prophylaxis must be observed in 

 wet seasons, and consist of measures based on our know-
