correct register of the absolute quantity of rain which falls 

 in any year has heen noticed in the Meteorological Tables 

 of 1847. Eelatively, one year with another, there cannot 

 be any doubt of the accuracy of the register, as the reservoir 

 which receives the rain is emptied every morning at 

 9 o'clock, and by a self-acting syphon besides, whenever 

 the quantity which falls exceeds "25 of aa inch. The effect 

 of evaporation is therefore inappreciable, as the pencil of the 

 register marks the quantity as it falls. The area of the 

 funnel which collects the rain is 200 square inches ; and as 

 the reservoir contains 50 cubic inches each time it is full 

 0'25 of an inch of rain has fallen on that area.
