Gaiger's work on braxy, Balling's success in producing effective 

 inoculations for the prevention of lamb dysentery, are striking illustrations 

 of work which has already achieved a great measure of success in con- 

 trolling diseases which twenty years ago were altogether elusive. We 

 may hope that equally fruitful results will attend the investigations of the 

 Diseases of Animals Research Association in Scotland on ' louping-ill ' 

 or ' trembling,' and the work of McEwan in Kent on ' strike.' Similarly 

 those of us who are specially interested in hill sheep are eagerly watching 

 the work of the Rowett Institute. But although the sheep farmer has 

 reason to be grateful for the great advances of recent years, he knows 

 that his annual loss is still great, and he feels that it is in this direction 

 that research will be of greatest immediate help to him.
