    Excerpt from The Geography of Ptolemy Elucidated

    It was after this that the work really began. The idea was - if it may be so described - to get to look over Ptolemy's shoulder while he was at work, and to investigate each succeeding point, until they could be combined into a consistent whole. This led to a rather large and wide amount of preliminary reading, which, however, fully repaid the time it cost.

    The most fitting method of work seemed to be by diagrams. When a subject was selected, the preparatory lines were put in, but nothing was added until it had been thoroughly tested; thus some of these diagrams remained on the board for days, or even weeks, always in view.

    Plates III. And VII. Were among the most troublesome. The error of Alexandria in the former was, for a time, left as unaccountable, until it was reproduced and explained in Plate VI. The difficulty in Plate VII. Was that, however much the data or calculation might be varied, there was constantly an outstanding error of either 5' or When this was found to be the interval between Londinium and Greenwich (see Plate IL), it was welcomed as another verification.

    Thus the work went on. I had no theory to support, and no object to serve. My interest in the subject was my only incentive.
