In our last Nunj'ocr, page 158, we inserted a table ol" rules 

 far predicting the weather,' and which h.ad been for some 

 time circulating in MS. as the production of Dr. Herschel. 

 That gentleman having publicly disclaimed the table al-

 readers to insert the tbllowmg disavowal :

 of Sloui'Ji, near IViiid--C)r. 

 Many-oI the public papers, for i' len ({!!■! of liirie past, 

 have oceasionallv ascribed certain pre'diciious of \ht slate 

 of the weather to me ; and several of thciTi have lately <r;one 

 s ) far as actually to prefix my name (o what they have 

 called a Weather Table, in which, acctsrdino; to certani 

 hours of the eha^iffes of the moon, wind, rain, snow, fiost, 

 &c. Sec, arc prognosticated. Such a tabic, by some mi'^tal-;e, 

 has even been vcrv lately itiserted into a very respcctal>la 

 Philosophical Mairazine. In justice fo mvseif, ihereforej 

 I think It highly necess.Tty that tise public should be unde- 

 ceived by uiy declaring tint the table prel^ended to be of my 

 ccmst ruction, as well as every pro2:nos!'knf'i';i»iV'of the state
