Box 77, MORDIALLOC Victoria -3195 Your Department was recommended to me by the Na- tional Meteorology, Brd.Rapp, Paris, as being one of the most qualified in Australia to answer to my request of information. I would be desirous to lQlow your opinion about supposed meteorological-phenomena having created several sets of circles in cornfields of England these last years. These sets of circles have been located by different persons, and according some of them, the first times they were spotted, there were no tracks of paths nor footprints left by persons, what would rule out eventua l hoaxes~ apparentl~. One of my English correspondents, Dr. G.T. Meaden, Bradford-on-Sea, editor of The Journal of Meteorology theory about these sets of circles, relative to whirlwinds crea- ted by thermals in specific topological and climatol0gical ci~: t ances, having a standing anticyclonic VGrticity of short duratwr But in spite of the plausibility of this theory, I remain very dubitative for tne following reasons: 1)-Since five years that these sets of circles are reported in England (Ten cases up to now), so far as I can remember, no case of the same kind has been reported in other countries, in France particularly, but I have not checked in Australia. 2 )-We f"JJ.ow one case of three circles and nine cases of five circles following the symetrical patterns drawn below: Three circles Five circles 3 ) -These circles are always perfects or almost perfects, placed al\oTaYS in a symetrical mannero The set of three circles being on a same axis; the four "satellites of the sets of five circles being placed in a square form, in the corners of thi: figure, the l arger circle being in the centre of this square shapeo Please see the photostat of a picture showing a preci se case, enclosed in my letter. )-The cerea l plants are laid down clockwise, following a spi- ral pattern outvmrds from a central point. Never in the oppo site direction. 5)-The edges of these circles are neatly outlined, without in- dentations, nor disturbed plants l aid dovm in all directions, >r. Director, would you be so kind as to send m~ ' not only your opinion about these cases o.f multiple circles, but' als< a maxluum o.f serious data (Photos, reports ) about possible identical cases having been recorded in your Department ? More, if you know former cases, even before the W. W.IJ any clue concerning themwould be very appreciated. Of course, I am disposed to pay the cost of all the documents that you will be able to send me. The price, for me, is without importance. hope that my letter will be received with .sympathy and honoured without the least difficulty in a positive manner. I am not hurried, consequently, ;you maY take all your time. In advance, thank you very much for the assistance of your Department in my re~earches. Yours very truly, Jean Sider, PS: In the following issues of "The Journal of Meteorology'~, ~ you will find ntl.!il:erous infor-~J "'. mat ions about these sets of circles: .. #,, /~
