Register of Rain fallen at Tavoy . 
[Dec. 
The same rain gage, consisting of a glass decanter and a brass funnel, has been 
used throughout the four years’ observations, and has always stood exposed in the 
same situation, about four feet above the flat roof of the S&gar Mint Building. 
The funnel is of a conical shape ; the mouth of it, which receives the rain, is 
surmounted by a cylindrical brass ring, one inch in height, and of such thickness 
as to afford additional strength to the funnel ; its diameter is accurately adjusted 
(on a lathe) to present an area to the falling rain of exactly ten square inches; the 
upper exterior edge of the ring is rounded off, leaving a somewhat sharp angle in 
the inside. 
The tube that conveys the water into the decanter, is long and narrow, to coun- 
teract loss by evaporation. At its upper end, it is cemented into a waxed cork 
which fits firmly into the mouth of the decanter. A conical broad rim of brass is 
soldered to the bottom of the funnel just above the cork, projecting beyond the 
mouth of the decanter, over which it fits close, and prevents any rain from getting 
into the decanter from the outer sides of the funnel. 
The height of water fallen in inches, is estimated by weighing the water in the 
decanter.
