A correspondent writes: "Thefollow ing trick is new, í ttúnk, and I there f ore inforru you concern ing it, if you choose to give it publicity: "Act. 1. - Aman introduces himsel: at my office as Dr. E. L. Adarns o Stroudsburg, Pa., talks(and talks learn edly about the throat) of sending a pa tient of his, a Mr. Heury Sawyer, in consultation. He theu speaks of desir ing to buy a spray apparatus; asks m of whoin. I recommend B. As the 'doe tor' is leaving he asks incidentally for one of my cards. It is given. "Act 2. - He afterward writes on my card a lino of introduction to B; presents it, saying he was sent by me, giving details. He orders the apparatus and desires it sent to Dr. Adams, street (who proruptly replies by telephone, saying he knows nothing abont it); presents a check made payable to his order, indorsed .by hini, in payment for the spray and receives a balance in cash (in this instance $10, I believe). "Act 3. - Check returned; no good. B. writes to Stroudsburg. No Dr. E. L. Adams and no Mr. Sawyer reside there or are known to the postmaster. I, of course, have never seen the Mr. Sawyer. "Act 4. - The bogus and plausible representative pf the medical profession has the money. The tritík is, of course, capable of various modifications. " An old trick is being worked upon the members of the medical profession with success in several instances. A man calis at the doctor's office at a time he knows he is away. Asking for the doctor and learning he is out, the man is, oh, so sorry, but maybe the good doctor's wife would aiiswer. The doctor's helpmate is summoned and is informed that the visitor is a patiënt of the doctor and lives (in one instance) in Newark, N. J. He is anxious to settle a bilí of $ 2lJ and asks the wife to give a re ceipt for that sum. The good wife, overeóme both by the visión of a f20 debt being settled and also by the flattering remarks of the pleasant mannered fellow, gives the receipt. In.exchange he presents a certified check for $25, gets the $5 in change, and - well, in due time the poor doctor jots down in his account book on the credit side, "Forexperience, $5."
