Yes that's right but I think that John has abandoned his idea of an analemmatic dial in favour of this suggestion of a conventional horizontal dial but one without a gnomon. Instead of a gnomon he would use a human standing at the correct spot for his height. This person's head would therefore form a nodus whose shadow would fall on hourlines drawn from the dial's origin. Not only would it make it easier to use in low latitudes it would also be easier for use by persons of significant variation in height - both problems with true analemmatic dials. I only know of one such dial in the UK but there may be more in the US. Sorry if we have confused you by our mail Patrick
