REPORT OF THE KING INSTITUTE, GUINDY

7

       2. Autogenous vaccines for treatment.—The total issued is a little more than
last year. As usual very few returns on the results of treatment were received.
An analysis in Table IX shows that good results distinctly preponderated.

       3. Miscellaneous supplies.—The Institute was of help to many hospitals, in
supplying sterile solutions for injections and various media and cultures. A larger
quantity of media and glass capsules, etc., were supplied this year—vide Table X.

       4. Specimens examined.—Table XI gives details. The total of examinations
at this Institute is larger than last year's by about 10,000. This is due firstly to
a large increase (5,200) in the number of Wassermann tests for syphilis, secondly
to an increase in the examinations of faeces for dysentery and typhoid and
thirdly to an increase in the specimens examined by investigation units.

       The increase in the Wassermanns is partly due to the investigation into the
extent of venereal disease in the population by examination of patients in
Hospitals and Jails carried out for the information of the British Social Hygiene
League Delegation.

       5. Sera issued.—Details are given in Table XII. The total issued is larger
than last year's by 2,721 ampoules. The increase is in all the sera issued.

        In this year's report, Tuberculin and other vaccines bought have been
removed from Table VIII and added to Table XII, so that this now gives details
of all sera and vaccines that are bought whereas Table VIII mentions only
vaccines that are manufactured at the Institute.

       6. Cases of interest.—(a) From a case of continued fever after delivery an
organism of the para-typhoid group was isolated from the peripheral blood which
did not react serologically to any of the known types A, B and C.
          (b) From a case of acute meningitis which proved fatal, a growth of
para-typhoid C was obtained from the cerebrospinal fluid.

(C) PUBLIC HEALTH SECTION.

          I. Water.
         II. Public Analyst.

        The Public Analyst, Mr. H. Hawley, has been in charge of this section
throughout the year and has colloborated in writing this portion of the report.

I.—WATER.

       1. Work done.—As usual samples from all protected supplies have been
examined twice during the year. In addition, an unusually large number of special
investigations have been made. Table XIV gives the nature and the number of
examinations made. Table XV refers to water-supplies which have been examined
as a matter of routine and gives details—as in 1925-26. Comments on some of
these and particulars of the special investigations are given below.

       2. Municipal water-supplies.—Supplies that call for particulars mentioned are
the following:—

          Adōni.—The unsatisfactory position of this supply reported last year, continues to exist, but
the municipality has recently reported to Government that action is being taken.

          Berhampur.—For a time, unfiltered water was added to the filtered supply. This practice
was unauthorized and has now ceased.

          Bezwada.–The presence of an abnormally large quantity of free ammonia continues. The
Sanitary Engineer to Government has been addressed on the need for an investigation.

          Chidambaram.—A thorough overhaul together with systematic working under controlled
conditions under the supervision of the Superintendent of the Guindy Experimental Filters has
resulted in a satisfactory effluent from the mechanical filters.

          Madura.—The Kochadai gallery which since its inception in 1919, has been yielding a
bacteriologically good water showed deterioration and consequently had to be chlorinated. The
cause of the deterioration has not yet been found.

          Nellore.—In February 1926, the collecting well gave a sample containing a very abnormally
high proportion of free ammonia. This phenomenon is parallel to that occurring at Bezwada (see
above) and requires investigation.

          Periyakulam.—The slow sand filters continue to give bad results.
