had been steamed in my presence at Leigh; and by the courtesy of the
Fishmongers' Company I herewith give his report:—
"Nos. 272-279. "St. Bartholomew's Hospital, E.C.
" July 31st, 1906.
"Dear Mr. Towse,
”The result of the bacterioscopic analysis of the samples of Water, Mud and
"Cooked Cockles, which were delivered here on Sunday last by Mr. Roberts, is
"as follows:—
Samples of Mud, Water and Cockles, Nos. 272-279, taken 28th July, 1906,
from Maplins and Leigh.
Sample No. 272 (a) Mud.—Taken from the Maplins at a point off Black Tail
Spit. The mud was taken immediately below the surface, i.e., where
the cockles are embedded.
"Sample Mud A, Maplin Sands surface.—Has Spirilla (Sewage ?)
" per c.c.
"About 5,000 bacteria per 1 c.c.
"B. coli per 1 c.c., not per 1/10 c.c.
"No streptococci per 1 c.c.
"No sporogenes per 10 c.c."
Sample No. 273 (b) Mud.—This mud was taken within the same area as
sample (a), but at a depth of about a foot.
"Sample Mud B, Maplin Sands, 1 foot deep.
"About 5,000 to 6,000 bacteria per 1 c.c.
"No streptococci or spirilla per 1 c.c.
"No sporogenes per 10 c.c.
"Mud A has no growth per 1/20 c.c. Phenol broth. Mud B has growth per
" 1/20 c.c. Phenol broth.
"On the whole, I think neither Sample of Mud is bad, although Sample"
Mud A might be, on account of the spirilla (supposing these are derived from
"sewage), considered not so good as Sample Mud B."
Sample No. 274 (a) Water.—This water was taken at a distance of about a
hundred yards from whence the mud was taken and from near the
surface. The tide had been flowing for about an hour.
"Sample Water A, from Maplin Sands.—Very Good."
10 bacteria per 1 c.c.
"No B. coli and no streptococci per 1 c.c.
" No sporogenes per 10 c.c."
