EXAMINATION, 1937.

	Report No. and Date	Organisms produced on gelatine plates incubated at 20° C. for 3 days	Organisms produced on agar plates incubated at 37.5° C. for 2 days	B. Colt.	Streptococci	Cl. Welchii. (spores)	Remarks
Drinking Water	24502 22/6/37	46 per c.c.	9 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	There are some coliform bacilli found in quantities from 25 c.c. to 100 c.c. but none of them is of an excremental type. From a bacteriological point of view the water is satisfactory for drinking purposes.
	24503 22/6/37	38 per c.c.	6 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	Coliform bacilli are present in the higher quantities tested viz.:—50c.c.—100 c.c. but none of them is of a characteristic excremental type. The water may be considered fit for drinking purposes.
	24504 22/6/37	76 per c.c.	16 per c.c.	Not found in 100 c.c.	Not found in 30 c.c.	Not found in 100 c.c.	The sample contains no organisms of an excremental type and the water may be regarded as satisfactory for drinking purposes.
Bathing Water	35362 30/8/37	960 per c.c.	32 per c.c.	Present in 100 c.c. Not found in less	Present in 10 c.c.	—	The sample contains small numbers of excremental organisms, but not in excess of the number permissible in the standard for bathing waters. The water may therefore be considered suitable for bathing purposes.
