TO THE REV. DR. HORSLEY, SEC. R. S. 
DEAR SIR, 
Redde, April 14, 
1 7 74 * 
T HE following account of a 
ftorm of lightning was com- 
municated to me by the obferver Mr. nicholson 
teacher of mathematics in Wakefield, who is a very 
ingenious man, and a good eleflrician. I have no 
doubt of his having given proper attention to the 
phaenomena which he has mentioned, or of his 
exadtnefs and fidelity in defcribing them. Some of 
the circumftances appear to me to be very extraor- 
dinary ; and, as far as I know, quite new, not 
having been noticed by any writer that I have met 
with ; I therefore think it very proper that the ac- 
count of them be communicated to the Royal 
Society. 
Iam, DEAR SIR, 
Your very humble fervant, 
la JOSEPH PRIESTLEY.
