REPORT OF THE KING INSTITUTE, GUINDY
It is very desirable that the water so brought be lifted by a pump from the
waggon to an elevated tank and then distributed by taps.
South Indian Railway.
* Arni road.— The well water continues to be very bad. No action has
yet been taken on previous recommendations.
* Chingleput.— The
present source was very unsatisfactory. The
installation of the municipal supply was recommended.
* Kumbakonam.— The well yielded water of poor quality. The tapping
of a new source was suggested.
* Mangalore.— The provision of an elevated tank with distribution taps
on the platform was again recommended.
* Mayavaram.— The uselessness of adding bleach solution to the well was
again pointed out. Chlorination was recommended to be carried out in the ele
-vated reservoir.
* Tanjore.— Chlorination in the elevated reservior was again recommend

Improvements repeatedly urged in respect of the old well have not been effected.
Tiruvarur.— As at Mayavaram bleach solution is added to the well. This
is useless and only creates a false sense of security. Chlorination should be
carried out in the reservoir.
Bengal-Nagpur Railway.
Chicacole road.— The water-supply was unsatisfactory. Liquid chlorogen
was added to the well itself. This procedure is useless, wasteful and creates a
false sense of security. Systematic chlorination in the elevated reservoir was
recommended.
Naupada.— The supply was poor, although chlorination is reported to be
done every evening.
( d) Types of filters
—
Slow sand fitters at Berhampore and Vizagapatam yielded fair results.
The results from Cocanada and Kurnool sand filters were not quite up to the
standard. The sand filters at Ellore and Periyakulam were functioning as
strainers only. The mechanical filters at Erode and Masulipatam were worked
contrary to rules (without alum). Those at Chidambaram and Cauvery-Mettur
Project yielded good results.
3. Miscellaneous work in the Public Health Section.— Table XVI gives the
miscellaneous analyses done in this section.
Samples of water for boiler and industrial use were analysed and reported on.
Four samples of deposit from water pipes and boilers were received for mineral
analysis. Various chemical analyses of pathological fluids were made for the
clinical and bacteriological section, such as chemical examination of urine, deter
-mination of albumin and globulin in C.S. fluid, proteose in urine, etc.
(E) SPECIAL RESEARCHES.
( 1 ) Work for the Water and Sewage Purification Committee.— This is mainly
for the experiments at Kilpauk. The many tests needed are rather a burden on
the Institute almost monopolising the services of a Bacteriologist (Mr. Raghava
-chari) and also considerably adding to the work of the Chemical Public Health
Section. The Director continued to act as Secretary of the Committee and the
Public Analyst and Mr. Raghavachari as members during the period under
report.
The experiments on the improvements of percolators have been continued.
The effect of reducing the depth of the top layer of a percolator from 3
feet to only 1 foot was tried. Neither the new 1 foot top layer percolator
whether the material was gravel or broken granite did as well as a new percolator
