Colonies representative of those ascribed to "colon-

 B. })aracolon, an equally significant organism, was also 

 isolated from mussels 6 and 11. Staphylococci, B. lactici, 

 B. cajjsulatus and some aberrant organisms were also 

 isolated. 



Anaerobic milk cultures from the stomachs of mussels 

 1 to 12 were also made. All these without exception 

 yielded the typical enteritidis reaction. 



At the request of Dr. Sergeant I made a further 

 examination of the Crook Skear mussel bed. On February 

 19th Mr. Scott, Mr. J. Wright, Chief Bailiff of the 

 Northern Division, and I visited this bed. We went on 

 the Skear about the time of low water. There were few, 

 if any, evidences of sewage pollution on the mussel bed 

 itself, but on the sands above the skear, and particularly

 plenty of shredded paper, even distinct accumulations of 

 this in places. Mr. Wright told us there had been much 

 flood water in the Lime previous to our visit, and it is,
