Hon. Colonial Secretary,
New hygrometrical tables, in C.G.S. measure,
will be required when International C.G.S. units are adopted in
Hongkong, and it is very desirable that they should be construct-
-ed from the latest and most reliable data. Will Dr. Doberck
therefore be good enough to place the observations mentioned in paragraph 2 of his letter dated 19.1.17 at the disposal of the Director of the Royal Observatory, Hongkong, if he is unable to publish new tables within the next 6 months.
(Sa.) T. F. Claxton,
Dir. R.O.
