the operation. Thus the moment the rain begins to fall into the co- 

 nical collector, it is conducted by the tube into the receiving-cy- 

 linder, and begins to raise the float, and with it the deal rod, with its 

 pencil, which makes an oblique line upon the paper, compounded 

 of the vertical motion of the pencil and the horizontal motion of 

 the surface of the brass cylinder, and shows the quantity fallen by the 

 total height of the oblique line, and the rate of falling by the angle 

 of obliquity, and the time of commencing and termination of each 

 shower by the distances along the line. 



All the attention requisite is to wind up the time-piece from time 

 to time, and to take oif the paper from the cylinder and replace it 

 with a fresh sheet, marking the time on the paper when it is put on. 



The following table is an abstract of one of my gauges for the 

 year 1817 : in the course of this year, there were 21 days in which 

 the time-piece was more or less out of order, or omitted to be 

 wound up ; there were, however, eight complete months. 



It appears by the following abstract, that in 344 days there were 

 but 614-xTi- hours actual rain, being at the rate of l"" 47™ per day. 



The greatest rote of raining, I found to be on the 30th of June, 

 which for a few minutes was at the rate of 42^ inches per day. 



Yours, truly, B. Bevan.
