OF PUBLIC HEALTH, RANGOON, FOR THE YEAR 1928.

effect on the larvae was negative. On the same day four cartridges of
dynamite of one ounce each were detonated together. The bank up to
75 feet away vibrated and the water shot up to about 20 feet, but though
a few fish came floundering to the surface, no effects on larvae were
noted. These experiments were therefore altogether negative, and the
only explanation for it is that the water may have been too shallow, so
that much of the force was expended upwards instead of laterally as
probably occurred in Mesopotamia where bombs detonated deep in the
river resulted in wholesale destruction of small fish.

   Museum.—The Museum functions entirely as a Public Health
Museum. A number of models have been prepared by Dr. Fenn,
Assistant Bacteriologist, and the Museum is now serving the purpose for
which it was intended, i.e. illustrating by means of models, diagrams,
charts, photos, etc., various matters in relation to Public Health work.

   Buildings. —An animal house with six rooms opening into a courtyard
enclosed with expanded metal was constructed during the year.
