 He left me and took the slip of paper and examined it closely.
 It seemed to be nothing but stray fragment of foolscap, but it occurred to me that it might have a history it was here that my chemical knowledge came into play.
 I remembered that Alexander Bolton was chemist and also remembered that an ink could be made with analine, iodide of ammonia and chloride of zinc, in certain proportions, which had fresh, reddish tinge, and that it would fade out entirely in four days, leaving no mark on the pa- per. Bolton, no doubt, knew this secret, that he used to swindle the mechanic out of his earnings.
 The more l considered this subject, the more bee m, convinced that such was the case The note had been written with fadi, g ink.
 | But there was another chemical secret which probably Bolton did not know, & I had discovered 1t myself by accident. This treacherous ink, on fading out, leaves the zinc in invisible atoms in the papers, so that every line traced may be restored by the application of certain solution of sulphate of iron aud hydrate of ca cir1m. So, no sooner had MT. Campbell left my office, thaa hurried to drug store, where ob- talned the solution. ...
 Returning to my office, saturated a piece of plotting paper with drop of it, and appli d it to 8 corner of the blauk pa- per. The result made me jump up, clap my hands and y, Il with delight, for fresh and clear the dollar came out. knew not what hidden words the paper continu. d, and placed it III my pocket-book, corked up the vial-which was destined to prove wal of wrath to MT. Bolton-and went immediately, and brought suit against him for the recovery of the amount of the note, with interest and costs.
 A few days later, Alexander Bolton stood at the bar of justice, to answer in his own behalf. It se~med so easy to him, that he did not deem it necessary to employ any counsel.
 MT. Campbell swore to the facts he had related to me concerning the loan. MT. Bo.ton answered, on oath, that he had nc recollection of ever borrowing any money of the plaintiff If he did, where was the note? He would thank anybody to pro- duce it.
 ':Your honor,' said I, addressing the judge, 1T think can produce the note in question:"
 'sI understood you that it was not to be fou i'd, /" said Judge D., somewhat sur. pris-d.
 "It has never been lost," I said, as l took from my pocket the blank slip of pt- per, and passed it to him. ''This is it. D
 "I hope you are not t1ifing with the court" he said, as he glanced at both sides end perceived that it was blank.
 II am not, your honor." said 1, as I pro- ceeded at once to explain to him the chem. ieal fact have already described.
 l watched Alexander Bolton as did so, and notic> d that he turned very pale. When I had concluded, took from my pocket the vial containing the solution, saturated a piece of plotting paper with it, and press.d it upon the blank slip of pa per that lay upon the judges desk.
 A few seconds left it so, then lifted il up. confid-nt of the result and I was nct disappointed.
 The blank slip of paper was suddenly transformed into promissorv note, every word. letter and figure, as clear as sun- shine. e.-....
 It was note of six thousand dollars with years interest just due, dawn in ia vor of William Campbell, aud the sigma ture of Alexander Bolton was at the bot tom of it.
 Th- judge gazed with amaz' ment, from the note toward Alexander Boltcn, just ir time to discover that that tricky gentle man was skulking away toward the door.
 At the judgt's order he was broue h back bv an officer, and informed that te would have something more to answer fo' the amount of the loan, interest and costs
 And so he had. Abashed and terrified at the discovery of his unsuccessful swin dle, and in hopes of propitiating the court he at once gave his checs for the amount due MT. Campbell, and paid the costs.
 In view of his confession, he was let of with two years imprisonment, and don' suppose he will ever dabble in invisibl' ink again.
 This. my first case, attracted considera ble notice, and I have never since had to lounge in my office and yearn for clients.
