REPORT ON THE WORKING OF THE HARCOURT BUTLER
(3) Experiments to find out the viability of B. oxytocus perniciosus in
natural water collections and its resistance to sunlight. As an interesting
variation in the indol production was noticed during the experiment, it will
be repeated next year.
(4) Experiments to isolate vibrios from prawns caught in deltaic
districts of Burma.
(5) In connection with an outbreak of beri-beri at Yelegale Village of
Maubin Township towards the close of the year, various samples of paddy
and milled rice were examined. Three samples of paddy with a phosphoric
anhydride content of 0.53 per cent, 0.62 per cent and 0.64 per cent
respectively were unhusked in the laboratory with the help of .a mortar and
pestle. The samples of rice thus obtained were examined for P 2O5 with the
following results :—

A breakdown occurred during the year in the old cold storage
system of this Institute. As a result thereof, the prophylactic vaccines
had to be shifted to the Medical College cold storage and much
inconvenience was experienced for about a fortnight. Besides, there
was not sufficient space for the storing of vaccines. For these reasons,
Government was approached, and a new cold storage, worked by a
Freon gas system was installed during the year under report and is
working satisfactorily.
CINEMA SHOWS.—On ten occasions during the year, cinema shows
and demonstrations were given at this Institute.
MEETINGS.—During the year under report, 59 meetings were held
at the Institute by various Societies and Committees such as the
Burma Red Cross Society, the National Council of Women in Burma,
St. John Ambulance Association, the Health Exhibition Technical
Committee, etc. The Annual General Meeting of the Red Cross
Society was presided over by His Excellency the Governor of Burma.

Dissection of mosquiloes. —Fifty-two adult anophelines representing
10 species were dissected during the year.
(iii) Blood examinations ...
... 89.
(iv) Spleen census reports were received from 33 districts comprising
44 towns and 752 villages.
(v) Weekly reports were received regularly throughout the year
from (a) Kyaukpyu, ( b ) Maymyo, ( c) Lashio, and ( d) Sandoway, at
which places systematic anti-malaria measures were carried out.
(a) Kyaukpyu.—This town has been free from malaria to a remark
-able extent since the introduction of systematic anti-malaria measures.
Abolition of paddy cultivation was formerly advocated. Later
investigations however showed that these have now ceased to be the
breeding grounds for A. annularis. On this evidence, a recommen
-dation was made for reversion to paddy cultivation, and paddy fields are
now gradually replacing cocoanut plantation.
(b) Maymyo.—This town was inspected by the Malariologist in June.
Amongst other anti-malaria measures, he recommended bamboo
sub-soil drainage and herbage cover in selected areas. Subsequent
reports show that these measures have been met with great success.
(c) Lashio.—This town was also visited by the Malariologist in the
month of June. He recommended several new measures which have
been gradually adopted by the authorities concerned. There had
been a reduction of the spleen rate during the year under report as
compared with the previous year.
(d) Sandoway.—This town has been put under a systematic malaria
control scheme since April 1938.
Measures recommended in the report of the malaria survey carried
out during 1936 were being given effect to.
(v) Larvivorous fish .—During the year under report, 26,456 fish
were distributed to 17 districts. Subsidiary hatcheries were established
in the following places:
—
(1) Yamèthin, (2) Shwebo, (3) Magwe, (4) Myaungmya,
(5) Mandalay, (6) Bassein, (7) Tavoy, and (8) Myitkyina.
(vi) Distribution of Cinchona febrifuge. —A record of free distribution
of Cinchona febrifuge tablets is maintained in the Malaria Bureau of
this Institute.
CHEMICAL LABORATORY.—A total of 860 samples, comprising of 311
samples of water and 540 samples of miscellaneous foods and drugs,
were examined during the year.
Water.—Of the 311 samples of water, 61 samples from tube wells
were examined for the issue of permanent licences under the Burma
Underground Water Act, 1930. The remaining 250 samples were
received from Municipalities, District Councils, Town Committees,
Hospitals, Jails, Burma Railways and others.
INSTITUTE OF PUBLIC HEALTH,- RANGOON, FOR THE YEAR 1938.

Foods and Drugs .—Most of the samples were received from the
Port Health Department. A detailed statement of the 549 samples of
miscellaneous foods and drugs examined during the year is appended
to this report.
Ghee .—Of the 13 samples found adulterated, 4 were found to consist
entirely of vegetable fat.
Milk (fresh).—Out of a total of 137 samples examined, 120 samples
were found to be adulterated or otherwise unsatisfactory. In most
cases, water had been used as an adulterant. Cane sugar or lactose
was added in some samples to raise the specific gravity. In one
instance, common salt was added.
Mustard Oil.— Groundnut oil, being the cheapest of all edible oils,
was used as adulterant to mustard and sesame oils. No mineral oil
adulteration was detected during the year.
Rice .—The samples are grouped below according to their phos-
phoric anhydride contents :—
