INSTITUTE OF PUBLIC HEALTH, RANGOON, FOR THE YEAR 1936.
Port Health Officer, 4 were slightly adulterated, 2 were found to be
entirely vegetable fat, and the remaining 3 were adulterated approxi
-mately with 25.0 per cent, 89.0 per cent and 94.0 per cent respectively
of vegetable fat.
Mustard Oil.— Of the 24 samples of mustard oil received for exami
- n a t i o n f r o m t h e P o r t H e a l t h D e p a r t m e n t ,7
were found to be adultera
-ted with groundnut oil in varying proportions ranging from 8.0 per cent
to 25.0 per cent approximately, and in one of these traces of sesame
oil was also detected.
Patent Medicine.—One sample of a preparation under the name of
"Antitap"—a malaria specific, was received from the Malaria Bureau
for determination of the quinine content. The total contents of the
bottle measured 75 c.c. and the total quinine content was 21.1 grains
only as quinine sulphate. According to the directions for use furnished
therewith, the bottle contained 9 adult doses which provides only 2.34
grains of quinine sulphate per dose.
Rice.—Fifty samples of rice out of a total of 98 samples examined
were found to be below 0.40 per cent in phosphoric anhydride content.
The samples have been grouped as follows according to their
phosphoric anhydride content:—

A sample of rice taken by the Port Health Officer, Rangoon, from
the M.V. "Derbyshire" on 26th March 1936, was found to contain a
very high proportion of phosphoric anhydride, viz., 0.65 per cent.
The sample was parboiled rice.
30. INVESTIGATION AND RESEARCH— Grease
and oil mixture.—Under
instructions from the Director of Public Health, Burma, this investiga
- t i o n w a s t a k e n u p . T w e n t y - f o u r s a m p l e s o f t h i s m i x t u r e w e r e
purchased personally by the Head Clerk of the Institute from different
quarters of the town. All the samples were sold as comparatively
cheaper brands of ghee intended for human consumption, e.g., paratta
frying, etc., and not as lubricating oils for machinery. The prices
tendered for the article were found, in certain cases, to be equal to the
actual retail price of genuine ghee.
A table showing details of these samples together with their
analytical constants is appended.

REPORT ON THE WORKING OF THE HARCOURT BUTLER
Of the 24 samples examined, 15 were found to be entirely vegetable
fat. Sample No. 2 contained the maximum quantity of ghee, viz .,
55.0 per cent and the rest from 2 to 12 per cent of genuine ghee.
Besides, sample Nos. 7, 13, and 17 were found to be extremely rancid,
and as such, unfit for human consumption.
Wheat flour and atta. —Twelve samples of wheat flour and 4 samples
of atta were examined with a view to finding out a relation between
their protein and gluten contents. In this connection, 8 other samples
of atta were examined in the previous year and the investigation is now
completed.
Vegetables.—Some of the common vegetables largely used by
Burmans were examined for their calorific values. This investigation
is still being continued.
Dried fish .—Eight samples were examined during the year. This
article of food is very largely used by Burmans and Indians alike and
the investigation was taken up to determine its food value. A large
amount of work in this line is intended to be carried out in this
laboratory.
31. MISCELLANEOUS ACTIVITIES—Laboratory Reagents.—This section
prepares most of the chemical reagents required for the various
analytical works it carries out. The standardization of acids and
alkalies against standard solutions obtained from England is done as
well. The preparation of important chemical reagents, viz., Millon's
reagent, etc., for the Bacteriological Department is also undertaken by
this section.
Forty-six samples of broth were examined for the oxygen absorbed
figure. This test is now regularly done for the Bacteriological
Section.
Several samples of cholera vaccine were also examined for deter-
mination of the concentration of carbolic acid.
32. TEACHING.—This is one of the heaviest items in the routine
duties of this department.
(i) Public Health Inspectors' Training Class .—Thirty-three lectures
in Physics and Chemistry were given to the students of this class.
(ii) Burma Health School .—Twenty-three lectures and demonstra-
tions in elementary Physics and Chemistry were given to the students
of the Burma Health School.
(iii) Medical School and Medical College.—A few lectures and
demonstrations were given to the students of the third year of the
Medical School and the fourth year of the Medical College on the
routine analysis of water, milk, rice and ghee.
Examinations in Physics and Chemistry, both written and oral, were
held for the students of the Burma Health School on completion of
their course of lectures.
