The first news ever heard of the so-call- ed Magnetic Light was, that the invention had been submitted to me, and that had pro- nounced it new and valuable. know Hot who put such report in circulation, but ae the project has becomea joint stock concern. and my name is still quoted in connection with it, deem itmy duty to state to the pub lie, that have never seen an apparatus oi experiments connected with the subject, nor have the parties claiming an invention of the kind ever offered to submit 10 me. in any way whatever.

 For several years common report has often made me the author of recommendations, the very reverse of what should have given. if my opinions had been consulted, and even some of the worst charlatans who have lately infested our community, have, have been informed, sustained their absurdities by a free use of my name. l have only to say, that before persons risk their property in specu- latlons, t is proper that they should seek some other authority than common hearsay.

 In connection with this subject of the Mag netic Light, equal to the sum- l will com muncate the result of some experiments which have made, comparing GaIyanic (not Magnetic Light with that of the sun.

 On the 25lh of February, the sun being clear, but past the meridian between two or three hours. l put in action powerful bat tery of 50 pairs of plates, each one foot square, and ignited charcoal at the poles.- The light was too intense to be looked at without pain to the eyes, but still when com pared with the direct sunlight by means of Rumiord's Photometer, the illumination was equal to that of the sun only when the screen was within two inches of the charcoal points.

 This datum furnishes the following results:

 ttrsf cost of Gaiuapic Light furnishing, ~ the distance of 200 feet, all Illumination eqaal 10 that Qf he sun.

 The unit of distance as by inc above ex- pertinent, is two inches with a single battery, and the number of batteries must be multi piled in proportion to the squares of the dis tances, in order to furnish an equal light This condition would require no less than one million lour hundred and forty thousand batteries, which at $50 each, would cost seyenty-two millions of dollars

 ttfs cost and interest per aHRitia, per diem, 6'c, of C Galrmdc Eght, at he distance of mile, eqaal 10 Aai of the sua

 By the same calculation, as above, it an- pears that with the distance extended to mile, that more han thousand millions of batteries would be required, (exact number, one thousandand three millions, six hundred and thirtytwo thousand four hundred and that the first cost would be more than fifty thousand millions of dollars.

 q, more than three thousand millions.

 Daily interest, eight millions, two hundred and lorty-nine thousand.

 Hourly interest, three hundred and forty. three thousand dollars.

 Interest per minute, five thousand seven hundred and twenty-four dollars.

 Interest per second, ninety-fve dollars and forty cents.

 The public will please 10 observe that inpute nothing improper to the persons claiming to have invented ihe Magnetic Light butt know nothing of what theyhay done, nor do say that a Magnetic .Light is all absurdity, il belongs not to me 10 say what has been, or whatmay be discovered in Eleerology. Magnetic Light has been known and exhibited fer fen wears; but it is a fitting 'siiro-lly lamp of 10 economical use. If any person shall improve it so as 10 make 1t uself. he will deserve credit. ButI have seen no evidence that such an improve ment has been made
