THE HONGKONG GOVERNMENT GAZETTE, 16TH JUNE, 1905.
The following conclusions were drawn :—
(1.) Odamine as a disinfectant is not so effectual as Lysol in killing the
plague bacillus.
(2.) The disinfectant power of Odamine is somewhat weaker than that of
Jeyes' Fluid.
The general results of my experiments showed that no advantage was to be gained by the wholesale use of Odamine. It was found to be less effectual as a germicide than Jeyes Fluid which is generally employed in Hongkong as a disin-
fectant and deodorant.
It
Disinfectol. This is a Japanese product and prepared by the Formosan Gov- ernment. It is a thick fluid of dark brown colour. It has a pleasant smell. mixed easily with water forming a milky coloured fluid. It is strongly alkaline in
reaction.
In examining this preparation the usual bacteriological technique was em- ployed. Solutions of different strengths of Disinfectol were prepared and brought into contact with living micro-organisms growing on solid and liquid nutrient media.
