REPORT OF THE KING INSTITUTE, GUINDY
the Indian Research Fund Association.
Cholera bacteriophage was also supplied to
some of the districts where cholera occurred
particularly to Ganjam. Cholera bacterio
-
phage at first comprised Asheshov's three
types A, B and C, but towards the end of
August 1932 and early in September three
more types which we call D, E-1 and E-2
isolated by Lieut.-Col. J. Morison, I.M.S.,
and Capt C. L. Pasricha, I.M.S. (to both
of whom we are greatly indebted), were
incorporated in our Bacteriophage mixture.
During the 5 months ending with September
1932, 98,000 c.c. of cholera bacteriophage
were manufactured and bulbed, of which
81,540 c.c. were issued. The entire supply
was made to the Public Health Department.
To test its presence in supplies to which it
was added, 33 samples of water were ex
-
amined. All these came from the Pushkaram
festival area. No cholera followed this festi-
val, but just as one swallow does not make a
summer, so here we may not yet attribute
this absence of cholera to the effect of the
use of bacteriophage. Its manufacture is
being continued and time will show whether
the spreading about of bacteriophage does,
as is hoped, greatly diminish the prevalence
of cholera.

BACTERIOLOGICAL, CHEMICAL AND SEROLOGICAL
EXAMINATIONS FOR CLINICAL PURPOSES

Surgeon Y. S. Narayana Rao. The
extensive work done is shown in the table,
There has been a great increase in the num

ber of agglutinating tests for dysentery
—
from our figures here by far the greater
proportion of cases of dysentery seem to be
of bacterial origin. The number of speci
-
mens of cerebro-spinal fluid for Lange's Gold
test has also increased. The chemical tests
reported were done in the general chemical
section.

raman. As seen from the table the total
number of tests done was 34,458 which is
2,400 more than last year. At present on
all ordinary specimens the Kahn test is first
done. If possitive a Wassermann test is also
done. The correspondence between results
The first point to note is that the negative
Kahns here mentioned do not refer to all the
specimens found negative by Kahn (which
were 15,914) but only to those that for
various reasons were also examined by the
Wassermann test. As seen, the correspond
-
ence between the two tests is fair, but
judging from the high percentage of positive
Wassermanns in doubtful Kahns the corre
-
spondence is not as close as it might be.
Delayed examination perhaps partly accounts
for this, for delay after taking the blood
tends to make what should be a Kahn posi
-
tive into a Kahn doubtful reaction.
WATER ANALYSES.
1. Charge.—For the first six months the
Public Analyst Mr. Hawley, later Mr. T. N. S.
Raghavachari, and finally the first Assistant
Director Major Webster. The general
Chemical section which deals mainly with
water work was under first Mr. K. V.
Sundaram Ayyar and later Mr. N. Swami
-
nathan. The Bacteriological section has
been under first Mr. T. N. S. Raghavachari
and later Mr. P. V. Sitarama Ayyar.
2. Total work.—As seen from Table V,
6,000 odd samples were examined. This is
less than last year because the number of
samples from the experimental filters was
cut down. Visits to Kilpauk were reduced
to three a week instead of daily as formerly in
order to lessen expenditure. The results of
experiments are recorded in Part II. The
supply at 17 railway stations was specially
examined for the Pushkaram festival at
Rajahmundry. There was a certain amount
of other work done in this section such as
sewage analyses and tests for disinfectants—
details are given in Table V. Six samples of
dye water were sent from Calicut to learn
whether the discharge of the dye water had
anything to do with development of an
obnoxious smell in the municipal sewage.
It was alleged that trouble had developed
only after the erection of the dye works.
Sulphuretted hydrogen was detected in the
sewage itself. The method adopted by
the dye works of adding bleach liquor to the
dye water before discharge to remove sul
-
phuretted hydrogen was successful except in
one sample.
3. Municipal and other protected sup
-
plies.— The number examined, 1,306 samples,
is a little greater than last year—1,267
samples, because 11 new supplies were
