Royal Society, was thought worth their 
acceptance. I have, on the other fide, fent, as you 
defired, the height my rain meafurer ftands above 
the ground, which, if you think proper, may be 
added to my former letter. Mr. Edward Lawrence, 
who obferved the rain at Stamford part of the time 
which I have done here, generally found more water 
in his meafurer which flood on the ground, than I 
did in mine; but I cannot depend on his obfervations„ 
becaufe I have been told the fervants at the houfe 
ufed to play him tricks, and pour into his ciftern 
more water than fell in, to which a thing on the 
ground is very liable. 
Mr. Lawrence alfo obferved the latitude of Stam- 
ford with a quadrant of Mr. Sifibn’s making ; and as 
it is ufeful to preferve fuch things, I have extracted 
the obfervations from his book, and fhewn the lati- 
tude deduced from them. 
My rain ciftern has all along flood on the top of a 
wall, where another meets it at right angles. The 
top of the ciflern on the North fide, is y feet 3 inches ;
