I have the honour to forward herewith the report of the Micro-Biological Section
of the King Institute. This institution as usual is doing good work. The existing.
accommodation is inadequate for the work the Institute is called on to undertake.
Additional staff and accommodation are necessary. I intend addressing Government
on the subject at an early date.

REPORT ON THE WORK CARRIED OUT IN THE MICRO-BIOLOGICAL.
SECTION OF THE KING INSTITUTE OF PREVENTIVE MEDICINE,
GUINDY, FOR THE YEAR 1910.
FOR the first half of the year under report there was no change in the staff, but
early in June Captain W. S. Patton, I.M.S., the Assistant Director, was placed on
special deputation work to investigate the life history of the parasite causing
" Oriental Sore ".
By means of this investigation it is hoped to clear up some of the points in the
life history of the closely related parasite of Kala-Azar and the means by which
this disease is transmitted. Kala-Azar being a fatal disease and one, so far as
we are aware, that is confined to human beings, it is impossible to reproduce it
experimentally.
Captain Patton's work is still in progress and will form the subject of a special
memoir. No officer was appointed to carry on Captain Patton's work in so far as.
it was connected with the Micro-Biological Section of the Institute.
In July, V. Govindaraju. Mudaliyar, B.A ., Junior Laboratory Assistant, was
transferred to Bengal, and his place was filled by R. Venkatakrishna Mudaliyar,
B . A .
The year has been an exceedingly busy one for the section. In all directions
the volume of routine work has increased and several new branches of work have
been started.
For sometime back it has been evident that the accommodation in the existing
building of the section was inadequate even for existing requirements, and that the
increase of work bound to come in the future as the functions and the advantages
offered by the laboratory became more widely known, and as fresh problems requir

staff.
Early in the year detailed plans for large additions to the present building, and
for practically the entire re-equipment of the section, were submitted to Government,
and these have received administrative sanction.
During the year the systematic examination of the water-supplies of the
Presidency was continued. Each town supply was examined once a quarter, and each
jail supply twice a year. In addition a considerable number of samples were examined
for private persons or firms and a further considerable number for the Sanitary
Engineer to Government in connection with the institution of new supplies.
As was the case last year more stress was laid on the classification of micro

purifying agencies than into the more or less artificial groups depending on their
behaviour to sugars or other chemicals. Owing to the increasing amount of work
that had to be dealt with in other directions, it was unfortunately impossible to find
time for farther experiments on the subject of relative resisting power. There still
remains therefore a considerable gap in our knowledge on this point. More than a
third of the samples examined show the presence of organisms whose powers of
resistance have not been determined. Probably however comparatively few species
viii
Educational.—The usual courses in Minor Sanitary Engineering and in Vacci-
nation were held during the year. In the Minor Sanitary Engineering class there
were forty-three students, but this year no Assistant Surgeons joined the class. At..
the final examination 10 students passed in the first class and 28 in the second_
class.
There were thirty students in the Vaccination class, and all of them obtained
qualifying marks in an examination held at the end of the course.
The staff of the section have worked well, but I wish to draw attention to the-
excellent work done by the Senior Laboratory Assistant M.R.Ry. T. Sithapathi
Aiyar, L. M. & S. In addition to the large amount of routine work involved in the.
analysis of water and in the examination of routine specimens, the Senior Assistant
has devoted a great deal of time to the above noted examinations for the presence of
Spirochœta pallida and to the preparation of bacterial vaccines. No less willing
worker could have got through so much.

REPORT.
Chemically this water shows strikingly high figure for oxidised nitrogen which shows that the water is
derived from some polluted source but that natural purification process have brought about considerable
improvement. The small trace of organic matter left unoxidised is however of animal origin.
Bacteriologically there were too many fœcal germs and too many species represented in the lake well
water, though none of these are objectionable in themselves. The water from the kitchen tap is somewhat
better, the fœcal germs being considerably reduced in number. On the whole the water is better than it
was at this time last year, but not so good as it was in October.

REPORT.
The Cannanore Jail water-supply is not in a satisfactory condition. Each successive half-yearly exami
-
nation reveals progressive deterioration. On the last occasion two of the wells showed faecal germs in 0 . 1 cc.,
on this occasion two such wells rank best, and. no less than four show one hundred faecal germs to the cc.
These four samples are derived from well Nos. I, II, IV and the tank, and they all show a large variety in the
species present. This indicates that the pollution has been extensive and although on this occasion there is no
evidence that it has been recent there is also no reason why it should not become so, as was the case with well
No. III last time. Well No. II and the Tope well do not show quite so many fœcal germs, but there is the
same diversity of species indicating extensive pollution. All the wells show far too high total counts.
Chemically the waters are not at all bad. Wells No. II and No. IV with an eleven to one ratio between
albuminoid nitrogen and absorbed oxygen are perhaps the best.

REPORT.
In that it contains no evidence of recent pollution the Palamcottah Jail water must be held to be better
than it was on either of the two previous examinations. If, as is not improbable this is associated with
a s p e l l o f d r y w e a t h e r , i t w o u l d p o i n t t o t h e s o u r c e o f t h e s e p r e v i o u s c o n t a m i n a t i o n s h a v i n g b e e n o f l o c a l
origin, and. therefore preventible. On the present occasion the total count is still too high though better than
in October, but there is a large increase in the excremental germs. These are however of the more resistant
k i n d s a n d i n d i c a t e o l d p o l l u t i o n o n l y .
The results of the chemical analysis support the bacteriological findings. The figure for oxidised
nitrogen is decidedly high indicating antecedent pollution. The small amount of organic matter left
unoxidised is of animal origin. The high figure for free ammonia is probably due to an accidental occurrence.
