were lifteci up and twirled about in the air like a shnttlecock, and 

 ]>rt'ci]ntatod over tlie adjoininj;- hedge with a tremendous erash. 

 At Ktiisworth one barley stack Avas completely strewn over the 

 field from whence it had been gathered ; to use the words of the 

 owner, " the corn was not only carried into the field again, but 

 spread out and thrashed," nearly the whole of the grain being lost. 

 At Woodhall Park a singular sight occurred at one of the tumbling- 

 bays, where the spray was driven some 30 or 40 feet in height, and 

 for a considerable distance. 



Out of several sets of readings of the barometer and thermometer 

 I have selected the following. For pressure I give the observa- 

 tions of Mr. Hopkinson at Watford and of Mr. "Wortham at Eoyston, 

 both being the readings of standard instruments. For temperature 

 I give the observations of Mr. Hopkinson again, and my own at 

 Throcking, because they are strictly comparable, verified instru- 

 ments being in each case inclosed in a Stevenson's stand. Other 

 obsei-vations with which I have been most kindly furnished agree 

 very closely with these. I have also given the amount of rainfall 

 at as many stations as possible, an m placed after a value indicating 

 that it is the maximum fall of the month.
