A PUZZLE. [To nut Enzroz OF TIER ,, Brzcznose."] SIR, —Tbe letter

of " J. H. M." in your last issue affords no solution of my puzzle, for the moon would not be visible to

the naked eye on either January 21st or 22nd, forit would in each case be within eighteen hours of the conjui2ction, and that is far too near the sun for it to be discerned by the naked eye. Travelling west such a distance as that from New York to Chicago could only benefit the observer to the extent of an hour, and there are several hours to make good. I saw the moon for fifty-seven days without travelling at am, Crowhurst, College Road, Upper Norwood.
