plea(ed upon that fcore to Pardon my delay in obeying 
your Commands : I wifli they had ceen more txadly 
made, and (hould have been lo, had they been intended 
for any thing but my ov/n Satisfaction, and enabhng me 
to give fome conjtfture at the Prr portion of Rain that 
falls in this County, with that at London, and in other 
Parts of this Kingdom. But in this 1 have not yet at- 
tained my defired end, not having heard of the like 
made in any Part of England-, though a Friend or two 
had promifed to undertake and affora me an Account of 
their Obfervations ; but it may be they did not think it 
worth their while, or that it would prove more irouble- 
fome than I have found it : For I only fixed a round 
Tunnel of ii Inches Diameter to a leaden Pipe, which 
could admit of no Water, but what came through the 
Tunned by reafon of a' part foder'd to the Tunnel ic 
felf, which went over the Pipe, and ferved alfo to fix it 
to it, as well as to keep out any wet that in Stormy 
Weather might beat againft the under part of the Tun- 
nel, which was fo placed, that there was no building 
near it that would give occafion to fufped that it did 
not receive its due proportion of Rain that fell through 
the Pipe fome Nine Yards Perpendicularly, and then was 
" bent into a Window near my Chamber , under which 
convenient VefTcls were placed ta receive what fell into 
the Tunnel,- which T meafared by a-Gylindrical Glafs at 
a certain mark, contginirg juft a Pound, or iz Ounces 
Troy, "and had marks for Im^ller parts alfo 1 prefer'd 
this w^y of finding the Content of my Veflel for mea- 
furing the Water btlbre any other, ot Gagmg of fmall 
Cubical or Cylindrical ones; where an mconfiderable 
and almoft indifcernible Error in theD merfions will 
prove muci^ g-eater in the Ccnrent ; v>hereas in the 
other way, r "V:cied the Cylinder it felf be fmall, or
