ifo me afar e the Quantity of falling Rain 5 by Jl/r. Townlcy.

MR. To'vcnley^ fixed a round tunnel of 12 inches diameter to 
a leaden pipe, which would admit of no water, but what 
came thro' the tunnel, by reafon of a piece foldcred to the tunnel 
itfelf, which went over the pipe, and ferved alio to fix it thereto, 
as well as keep out any wet, that in ftormy weather might beat 
againft the under part of the tunnel, which was lo placed, that 
there was no building near it, that would give occafion to lufpcd: 
that it did not receive its due proportion of rain that fell thro' the 
pipe, about nine yards perpendicularly, and then it was bent into 
a window near his chamber, under which convenient vefTcls'were

cf this cylindrical glals, he kept an account of what rain fell, and 
generally twice or thrice a day ; what rain he found in the recei-

and letting down the parts of a pound remaining in the glals 3 by 
the help of which latter, and the parts remaining at any time be-

end of one month fuppolc, from the pounds thrown away, and 
the parts remaining at the end of another, he found the quantity 
of rain fallen between thelc two times, and that in liich a manner
