Conishead Priory, near Ulverston, in Morecambe Bay, 
The bed was examined and samples were taken for 
analysis. No indications of sewage on the bed itself 
could be detected. The analysis gave what I regard as 
satisfactory results: —In 1/25th part of a mussel there 
were 13, 15, 20, 31, 10 sewage bacteria (in 5 estimations). 
Considering these low counts, and the distance of 
the mussel bed from any considerable source of pollution, 
I think that the latter may be regarded as free from 
serious contamination.
