"(4) To undertake to carry out the Regulations as shown on a form similar
“to that attached hereto.
“The Certificates will be submitted to the Medical Officer of Health of the City
“of London, who will authorise registration.
“It is suggested that the names of the Firms so registered shall be published
“from time to time in the Trade Journal, and later, that a label may be issued to
“those Members so registered, such publication to be deferred until sufficient time
“has elapsed to allow of the completion of the necessary arrangements—say
“six months.
“This label would be accepted generally by the public as a guarantee under which
“ the water was made, and would considerably enhance the value of the product.
“ It is intended that the Certificate shall be for a period of one year from date, and
“ shall be renewed from time to time provided the Regulations are carried out.
“To ensure compliance with these Regulations, it is suggested that an independent
“Inspector should, if necessary, be appointed.
“When readjustment of Factories and replacement of plant is necessary,
“reasonable time will be allowed.
Yours faithfully,
“W. DAVENPORT,
“ Secretary.”
“SODA WATER FACTORIES.
“Regulations.
“Water Supply.—The Water Supply used in the manufacture to be
“bacteriologically examined. The standard of purity should not be lower than the
“water supplied for drinking purposes in any district where the public water supply
“is used. The authorities supplying such water will furnish free bacteriological
“analysis of their water.
“Analysis of Products.—Bacteriological analysis of the goods produced must
“be furnished with the application for Registration. Bacteriologists have been
“approved by the Medical Officer of Health of the City of London and by the
“Society, and their certificates will be accepted.
“Filters.—If the water is quite pure no filter is necessary, if impure no filter
“is safe in practice. If filtration is considered advisable only special filters as
“approved by the Medical Officer of Health should be used.
“Rings and Stoppers.—The Medical Officer of Health of the City of London
“calls attention to the impossibility of properly cleaning stoppers or patent bottles
“having rings inserted in the bottles unless such rings are removed. In deference
“however to the general views of the trade, and inasmuch as stoppers are used to
“meet the demand of the public, he agrees that it will be sufficient if all bottles
“containing rings and stoppers and rings and stoppers when separated from the
“bottle are soaked in a solution of bi-sulphate of lime, (1 in 250, say¾ oz. to 1 gallon
“of water), and before using washed in a stream of running water.
