Coincidences from the library do not, however, limit themselves to one subject. Some years ago I was due to dine with a folklore friend at Twickenham, and at luncheon time, on the same day, I sauntered up Whitcomb Street to look at a second-hand book-stall, from which I had occasionally secured some bargains. On this occasion my luck did not desert me, for I purchased, for, I think, the modest twopence so dear to book hunters, four volumes of ‘Times Telescope.’ This was a sort of calendar published annually, from 1801 to 1821, describing itself as ‘a complete guide to the almanack, containing an explanation of Saints’ days and holidays, with illustrations of British history and antiquities, notices of obsolete rites and customs,’ etc. This last feature was, of course, the centre of attraction to folklorists, and the information collected in these volumes is certainly curious and interesting, forming as they do forerunners to Hone’s ‘Year Book’ and ‘Every Day Book’ and Chambers’ ‘Book of Days.’ I did not feel equal to taking all four volumes with me to Twickenham and back again home, so I left three of the volumes at my office, and proceeded with my remaining treasure to my dinner appointment. After dinner we were taking our coffee in my friend’s library, and of course talking of the books on the shelves, and I incidentally mentioned that I had that very morning secured a find. Upon informing my friend that the find consisted of some volumes of ‘Times Telescope,’ one of which I had brought with me, he eagerly asked to see it, and we proceeded to the hall where my coat was hanging. My friend took the volume from my hands, very hastily I remember, looked at the cover very narrowly, and then at the title-page, and proceeded with the volume in his possession, back to the library, where he promptly mounted the library steps and placed my volume in a vacant space on his shelves. It was the one volume he wanted to complete the series. The explanation was curious. He had collected all the volumes, but could not find a copy of this particular one. It had a curious misprint. The title-page showed the year to be 1812, but on the cover the figures had been transposed to 1821, and hence collectors had made mistakes over this volume time out of mind. The coincidence in this case was a double one. There was my purchase in the morning, and then my accidental selection of this volume to carry down to my friend’s house in the evening. Of course I left the volume there.
