136 On Astro- almo<iphcrical Science. 



None of the fragments of tiiis science which have fallen under 

 my ohservation are sufficiently minute to encourage a confident 

 anticipation of all the phosnomena which the clianges in the at- 

 mosphere produce: and I conceive that an unreservv"d communi- 

 cation of conj'crur^"^, — tho^e which have heen verified and those 

 not verifier!. \\\\\ be the most certain mode of putting to tlie test 

 this almo-- f.jjh)ded science 



With tiiis view an anonynious paragraph was inserted in The 

 Norwich Mercury, early in January 181() (the weather being 

 remarkably fine), announcing snow on the 28th or 29th of that 

 month. 



During more than twenty years I had observed d D or g of 

 Tj and ; had lieen coincident with snow in the winttr season, 

 and rain m\ tiie other parts of the year, fy and t? were to be 

 in cor.junctiou on tlie 2oth, but the moon was to be in conjunc- 

 tion with Saturn on the 29th. Some snow and sleet fell on the 

 25th at Norwich, latitude .52^ 44', and on the following days; 

 but tiie greatest descent was on the 2yth. 



I think I may venture to assert, that whatever the result of 

 the sltuatirinsof the planets, r.ccordnig to ancient or modern an- 

 ticipations, the effects are jiot fully manifested until the moon by 

 her position becomes a powerful agent. 



In Februrary, March -and April, whenever the j) and f? were 

 in any of the above positions, snow (more or less) invariahlv 

 fell. r . V I :i

Whilst delivering a lecture on meteorology on June 4th, I was 

 requested to select some days, and offer mv conjectures. On a 

 hasty reference to White's Ephemeris the following were se- 

 lected, having regard to the positions of the })lanets at and 

 near the times. For an almost immediate reply to an unex- 

 pected request, no more than a cursory view could be taken. I 

 have now subjoined the premises on which the conjectures were 

 founded.
