I had thoughts to add fomething about another kind of Ba~ 
r oj 'cope ( but inferiour to that in ufe ) whereof I have given lome 
intimation in one of the Ircdiminaries to the Hiftory of Cold. 
But you have already too much of a letter, and my occafi*

So far that Letter. Since which time, another from the fame 
Noble Obferver intimates. That, as for that caufe of the height" 
of the Cilyyc\-filver in Droughts, which by him is fufpedfedto be 
the elevation of Reams from the Cruft or Superficial parts of

th e Jtmofphere, being not, as in' other feafons, carried down 
from time to time by the falling Rain, it agrees not ill with 
what he has had fin.ee occafion to obferve. For, whereas a- 
b out March 1 2 th , at Oxford, the Qmcffilver was higher, than, 
for ought he knew, had been yet obferv’d in England . , viz. a-

that have interrupted our Jong Drought, as he affirms, he 
foretold divers hours before that the Quicffilver would be very- 
low, fa bluftering Wind concurring with the Rain) fo he found 
it at Stanton to fall f beneath 29. Inches. *

Letter <?/March 19. to his Cerrefpondeht in London • By change of'; 
Weather and Wind, the Mercury is funk more than an Inch 
fince I wrote to you on Munday laft, March 12. This laft night’
