ANALYSES. 
T'wo samples were collected again on February 11th, 
1908. They were taken frem the sands about 100 yards 
S.W. from Crosby Beach Mark. The results are as 
follows :— 
Dilution. No. of Red Colonies. Enteritidis Reaction.

2. The Flookburgh cockle seme 
The samples were taken from a place on the sands 
approximately S.W. by 5., and two miles distant from 
Humphrey Head. The fishermen were working all 
round, One sample (a) was taken from a fisherman’s bag, 
and the other (6) directly froma the sands, in the track of 
a “Jumbo.” About 200 yards from this place was a 
shallow sand-pool, and a sample of water was taken from 
this. This water was slightly turbid, doubtless because 
the men washed the cockles 1m it. 
The Flookburgh cockle sands appear to me to be as 
free from pollution by sewage as any place round the 
British Isles can well be. There are no great towns near 
them, and the rivers flowing into the Bay are very clean. 
It is such a place as one might expect to be above 
suspicion, and this is indeed what the bacteriological 
analyses indicate. | 
One c.c. of the water collected was inoculated, in 
duplicate, in neutral red agar, as above. Both plates 
were sterile. One c.c was tested for the Hnteritidis re- 
action and also proved sterile.
