Eight of the 25 oysters from the Conimicut Point bed or 32 per 

 cent, were infected with I^. coli., and JBact. lactls-aerogenes was found 

 in three of the specimens. 



Returning to the eastern shore, a number of 03^sters were collected 

 on the layings directly south of Nayatt Point, at about the same dis- 

 tance from the Fields Point sewer as those taken from the Conimicut 

 side. The channel keeps well over to the eastern shore at this point 

 in the river, and consequently the Nayatt beds are planted in about 

 20 feet of water and in the course of a much stronger tide than 

 that which sweeps the Conimicut shore. Fewer oysters from this bed 

 were found to be infected with sewage bacteria than from an}^ of the 

 beds previously examined. The accompanying table gives the results 

 of these analyses:
