 influence on the weatlier." 



Having advanced enough to prove tliat Mr. Frend was in pro- 

 pria penona a. conjectnrer in 181 !, 1 leave others, whilst re- 

 flfctine: on his present opinion, that grwily, attraction, the 

 inoon^s ivfliience on the tides, &c. are mere chimera, to assign 

 him his proper station, cither in or out of the ranks of modern 

 soothsavers. As I continue to acknou'ledQ,e the benefits we re- 

 ceive by the agency of the sun, notwithstanding the spots that 

 are discernible on its disc ; so I shall not cease to consider the 

 E.vening'i /Imi/iemenl to be a truly estimable work, altliough I 

 may not be persuaded l)y any thing contained therein to revoke 

 my opinion, that not the moon only but the constellations, the 

 moon and the other planets, are the agents in producing the 

 changes in our atmosphere.

LVII. On the Exhilition and Harrnonic Effects, of The Rev. 

 Mr. Liston's Euhakmonic Organ. By A Correspon- 

 dent. 



To Mr. Tilloch. 



Sir, — 1 HE exliibition announced in p.-lG4 of your last volume, 

 has at length begun to take place, and doubts can no longer be 

 entertained,whether co;rt/)o?«/f/ Stops on Organs, capable of being 

 perfectly t\.me{\, would be equally gratifying to the Ear, with 

 chords on simple stops, involving none or fewer discords in their 

 composition ; and the results have i)een most satisfactory and gra- 

 tifying to several select parties of Professors and Amateurs. 

 Mr. Parkii displayed nmch taste and execution in exhibiting 

 the Instrument : among the many full pieces which he played, 

 was the Hallelujah Chorus in 5 sharps ; the very novel and fine 

 effect of which, struck every one. Several of the most unusual 

 and extraneous modulations and enharmonic changes of mo- 

 dern Composers were exhibited, with new and very gratifying 

 effects, such, as perhaps the Composers thernseli-es were in part 

 luiaware of. In my latest visit at ^.'essrs. Flight and Robson's 

 a printed paper was put into n)y hands, which 1 wish to see pre- 

 served ill your pages: it seems to proceed on, and with good 

 effect to follow up, what is stated in vol. xxxix. p. 420, and 

 other parts of your very valuable work. 



I hope some of the able Professors and Composers who arc
